The German brand Weiss Cosmofen has conquered the European, American and Asian building materials markets as a supplier of high-quality construction chemicals at an affordable price. Founded in 1815, the German company produces adhesive, combined compositions for cleaning stubborn stains and connecting various objects. The secret to the success of the Cosmofen brand is the constant improvement of the range and monitoring of all consumer needs.
Reference: Chemicals for repair and maintenance of window and door frames, hinged ventilated facades, interior items, and decor, developed at the factories of the German holding Weiss Chemie + Technik GmbH & Co. KG in the city of Haiger in Hesse. The history of the holding began back in 1815 with a small enterprise for the production of leather glue, and by the second half of the last century, the Weiss Chemie brand became one of the TOP adhesive systems recognizable on the world market.
Weiss Chemie + Technik GmbH & Co. KG produces dozens of types of environmentally friendly sandwich panels, elements and structural components of hinged ventilated facades, detergents and cleaning products of the PUDOL brand for cleaning companies. The main direction of the company’s work is the production of adhesive compositions for:
- compounds of polymers, metals, wood;
- repair and maintenance of more than 400 types of surfaces and structures.
The chemicals are sold under the general brand name COSMO. The product catalog includes polyurethane, epoxy, dispersion, diffusion, instant (cyanoacrylates), and hybrid compositions. A separate catalog segment is occupied by biologically based adhesives and cleaning products COSMO Bio-based, which have bactericidal and fungistatic properties that are effective in inhibiting the synthesis of biomaterials (fungi, microorganisms). Cosmofen adhesives, sealants, and cleaners are purchased because they have been used by the world's leading construction organizations and factories for more than 200 years.
Description and scope
When installing plastic windows made of PVC, in most cases it is necessary to install slopes, which help hide defects that arise when the old window is deformed, give the structure a beautiful, harmonious look, and create an optimal level of thermal insulation.
Slopes should be used to protect against dust, dirt, noise, and create a reflective surface, thereby improving lighting. The joint with slopes and other parts must be sealed. For this purpose, you can use Cosmofen liquid plastic.
The products are one-component formulations with low viscosity. They set quickly, so the parts should be fixed correctly right away. The German manufacturer Weiss included special components that provide moisture resistance and ultraviolet protection.
The resulting seam imparts stability to plastic joints and has the following qualities:
- resistance to the influence of negative temperatures;
- low thermal conductivity;
- high resistance to external damaging factors.
The use of window glue is justified for securing any technological seams and attaching auxiliary elements - drains, protective strips, flashings. Using liquid plastic, you can glue products not only from polyvinyl chloride, but also from hard plastic, polystyrene, plexiglass, polycarbonate and some other types of plastic. Liquid plastic can be used to seal plumbing pipes and finally secure advertising banners.
Assortment of liquid plastic
The products produced in the “liquid plastic” line differ in viscosity. This leads to different areas of application, although there are no fundamental differences in the scope of use.
For example, Cosmofen Plus has a medium viscosity; its subtype Cosmofen Plus HV has a higher viscosity, so it bonds plastic surfaces more reliably. The materials in this series cannot be replaced with glue like Cosmo SL 660, 650 for plastic - they have a different operating principle.
Cosmofen PMMA for acrylic
Cosmofen PMMA is a solvent adhesive that is essential for instant bonding of acrylic. Widely used as a material for connecting window profiles with an outer layer of acrylic.
The area of use of liquid plastic is the production of advertising products and acrylic commercial equipment. Cosmofen PMMA is very resistant to solar radiation. The composition contains solvents and a number of polymers.
Main technical characteristics of liquid and frozen film:
- color - transparent, colorless;
- viscosity - 2000 MPa/s;
- film strength - semi-rigid;
- material density - 1.15 g/cubic. cm;
- the working time of the glue after application at room temperature (+20 degrees) and humidity 60% is 45 seconds;
- achieving strength - 16 hours;
- final hardening, distribution of solvent residues - 8 weeks;
- temperature during operation - at least +5 degrees;
- combustion temperature - +321 degrees.
Hardened glue should be removed in strips, tearing them off - the product can be separated from the materials without damaging them.
Cosmofen Plus for PVC
Cosmofen Plus is widely used by companies involved in the manufacture, installation, and repair of plastic windows and other products made of rigid PVC.
Can seal and glue ebbs, slopes, louvres and other additional profiles. Cosmofen Plus is used to connect plumbing pipes, gutters, and glues billboards and banners. It is highly resistant to temperature and ultraviolet resistant. The composition is diffusion adhesive based on vinyl chloride polymers in solvents.
Characteristics of the product:
- film - transparent, colorless;
- properties of the film after hardening - durable, withstands shock loads;
- viscosity - 2200 mPa/s;
- density - 0.99 g/cubic. cm;
- the shelf life of the glue after application at room temperature (+20 degrees) and humidity 50% is 60 seconds;
- functional strength - 2 - 4 minutes;
- curing time - 24 hours, final removal of solvent residues - 8 weeks;
- ignition temperature - +212 degrees.
The product is not used for gluing pressure pipes.
Cosmofen 345 adhesive-sealant
Cosmofen 345 sealant is widely used for sealing seams on parts of plastic windows made of rigid PVC. The resulting compound will be resistant to atmospheric changes, precipitation, and exposure to sunlight.
The glue does not spread over the surface, does not crack, gives minimal shrinkage, and can fill seams up to 5 mm deep. Contains silicone and is absolutely transparent, so it can be used for connecting translucent metal-plastic structures.
Where else can I use Cosmofen 345? The composition perfectly glues products from the following materials:
- tree;
- stone - natural, artificial;
- concrete.
With a surface width of 20 mm, glue is consumed at the rate of approximately 8 g/linear meter.
Cosmofen Plus HV for PVC
Liquid plastic Cosmofen Plus HV is used for quick gluing of solid PVC products. Most often, the composition is used in the installation of plastic windows to attach drains, protective strips, flashings, and a number of closing elements.
In advertising production, adhesive is used for attaching panels, profiles, boxes and banners. The product is widely used in plumbing work, but not for joining pressure pipes.
The glue is one-component, colorless, transparent, looks like a gel, and has high viscosity. The composition of the product is a solution of polyvinyl chloride on tetrahydrofuran. The resulting seam will be highly resistant to ultraviolet radiation, since the composition contains special substances - UV stabilizers.
Main characteristics of the glue:
- viscosity - 4000 mPa/s;
- density - 0.99 g/cubic. cm;
- the shelf life of the glue after application at room temperature (+20 degrees) and humidity 50% is 60 seconds;
- achieving functional strength – 2 – 4 minutes;
- final hardening is a day.
Cosmofen Plus S for PVC
The Cosmofen Plus S liquid plastic product differs from the others in color - this glue is white.
The scope of use is similar - glue is used to connect parts of PVC windows (slopes, ebbs, slats). In plumbing work, glue is useful for rain gutters and pipes (with the exception of pressure pipes). The material is used for the manufacture of advertising products.
The technical parameters of the product are the same as those of other adhesives in the Cosmofen Plus series. If the viscosity of the material is too high, it can be diluted with Cosmofen 380.
Cosmofen glue - a universal assistant
Content
It has long been known that glue is always needed in any household and that it is often impossible to do without it. The fact that today the choice of gluing products is huge is evidenced by the abundance on the shelves of construction markets and repair shops of various sizes. Every owner dreams of always having reliable, universal and inexpensive glue at hand. “Cosmofen” is still considered a new product among home helpers, but it has already gained a reputation as a means, as they say, for all occasions.
What are you talking about
The Weiss Chemie company is widely known not only in its homeland - Germany. Its products are popular on almost all continents of our planet. Advanced technologies and extensive experience allow her to create truly the best examples of finishing materials, industrial adhesives, solvents and more. Quite recently, this German company offered a unique product to the Russian market - Cosmofen CA 12 glue. The new product impressed both professionals and ordinary buyers, but we will try to tell you why and why in this article.
Advantages and disadvantages
Liquid plastic adhesives have a lot of advantages. Despite their recent appearance on the market, they have firmly gained popularity among window manufacturers.
The use of glue ensures diffuse welding (mutual penetration) in the joint area, resulting in the formation of a single part without changes in color or structure. This is achieved due to the fact that the liquid plastic has approximately the same composition as the PVC profiles themselves.
Other advantages of the series:
- resistance to precipitation, light, heat, ultraviolet radiation;
- absence of fungus and mold at the joint, even at high humidity;
- excellent strength, seam strength;
- environmental safety, harmlessness to humans;
- guarantee of color retention for 15 years (the seam will remain white or transparent);
- rapid hardening, the ability to quickly put the product into operation;
- good sealing of seams, protection from cold and drafts;
- no absorption of odors;
- the ability to use detergents;
- resistance to sub-zero temperatures.
The disadvantages include too rapid setting of surfaces. You should immediately position them correctly, since there will be no time to correct the location. Another disadvantage is the need for the product to be completely dry during operation; only after hardening will the joint be resistant to moisture.
The disadvantage is that some adhesives are difficult to separate from surfaces, which requires purchasing a special solvent. Liquid plastic does not work well on porous surfaces and is not suitable for producing elastic, moving seams.
Another serious disadvantage is the easy ignition of materials - you must work with them in strict compliance with safety measures.
Application of Cosmofen glue
Dosed drops, a thin strip or a dotted line, which can be used to apply “Cosmofen” to the gluing zone, will ensure its economical use and also eliminate the fear of staining the item.
Note You can remove excess glue using the cleaner Cosmofen CL-300 or the pharmaceutical preparation “Dimexide”
Alas, preparatory procedures before the process, such as: preparing the composition, choosing containers and bringing the surfaces to be bonded to condition - can curb anyone’s ardor and desire to get down to work. In this regard, glue from Weiss Chemie is close to unique. To work with it, you need basic cleanliness of the gluing areas and this will be enough for success. The cost-effectiveness of the glue will please its customers. Even minimal packaging will be enough to glue a lot of things together, and if there is still some left, you can rest assured that it will work for a long time.
Liquid plastic cosmofen
Note: Once the package is opened, the glue will remain functional for 30 days. Using it after this period does not guarantee the results that fresh (just opened) glue will produce.
Among the important, but least noticeable properties of the new adhesives, we name the following:
- Operating temperature range;
- Seam color;
- Ignition temperature.
As it turns out, not all components of the adhesive formulation are equally sensitive to high temperatures. As a result, the manufacturing company does not recommend using glue where the joint will be exposed to temperatures exceeding 75-80 degrees. For example, a glued spatula for turning cutlets or an outdoor thermometer may not withstand contact with high temperatures.
By the way, according to the product data sheet, the suspension ignites at 460 degrees. This indicator can be attributed to the advantages of the product, since not every glue can withstand such a high temperature.
Depending on the intended work on eliminating and sealing joints, today you can choose liquid plastic cosmofen by color. Today, the manufacturer, meeting the buyer halfway, offers white and transparent colors.
About the disadvantages
The main one is that it contains ethyl cyanocrylate. Note that this composition is obviously designed for small amounts of consumption. And yet, the manufacturer recommends ventilating the room in which work with Cosmofen was carried out.
It is not recommended to heat glued areas above 80 degrees; at this temperature, the glue begins to liquefy and the glued seam is destroyed.
Your desire to repair both this and that thing in the house can also be called an indirect disadvantage. The secret here is not complicated - working with this glue is a pleasure. Awareness of this comes after the first result of its use.
Cosmofen glue is your reliable assistant around the house, at work and when engaging in one hobby or another. European quality is part of our everyday life. By purchasing this product, you receive in return a universal product for gluing any materials under any conditions. Isn’t that what we expect when buying glue?
Note : Epoxy glue , liquid nail glue .
Restrictions on use
Small parts of windows and other small plastic products are set almost instantly. To glue larger items, you will have to wait a longer time.
There are some restrictions on the use of the Cosmofen liquid plastic series:
- if the products will constantly be in contact with a large volume of water, regularly getting wet, it is better to choose other means (liquid plastic can only withstand periodic contact with moisture);
- parts that are too porous should be pre-coated with special products; Cosmofen adhesives should not be used immediately;
- Aluminum products must have special coatings, otherwise the quality of the seam may decrease;
- use on polypropylene, PET can lead to a decrease in the strength of joints;
- if the surfaces have different thermal expansion, there is a risk of liquid plastic peeling off in the future.
Security measures
When working with the material, you should strictly follow the instructions for use and safety precautions. The composition contains dangerous components that are highly flammable. Smoking during work is strictly prohibited, as is working near other sources of fire.
It is recommended to work with gloves, as if the composition gets on your hands it will be difficult to clean. The room must be ventilated when working, since inhaling adhesive vapors is prohibited. Otherwise, it is better to wear a respirator or fabric mask.
Why is cosmofen glue valued?
If you know what you need from what you use to connect certain objects, Cosmofen glue is ready to provide you with all this.
The main ones:
- Speed of formation;
- Connection strength;
- Ease and convenience when working;
- No need for additional training;
- Convenient and practical packaging;
- Versatility.
Of course, few people will like the prohibitively long hardening of the substance with which you are trying to connect two or more objects. Very often, glue is used in emergency situations, which is when speed is critical. Weiss Chemie, which owns the patent for the manufacture of Cosmofen, guarantees a reliable connection within a few seconds after its application.
Only high humidity or low air temperature can increase the period of formation. Thus, deviations from normal humidity (60-65%) and optimal room temperature (+24 degrees) will make you wait 25% longer for guaranteed hardening or even more.
Please note: The manufacturer has established a temperature range for effective use of the fixing agent - from +5 to +75 degrees. This should satisfy almost any situation except extreme ones, in which the glue category will have to be changed to “special”.
The strength of the connection is another property, the importance of which there is no reason to doubt. German glue is ready to offer the highest quality, and with reliability that is comparable to that of the material (part, thing, object) before gluing.
Each of us has our own skills in working with small details. Don’t let miniature objects scare you - the special shape of the tube and the original nozzle will help even a person who is far from neat to glue together what they need without any problems.
Instructions for use
Applying the material is not difficult. It is very important to properly prepare the surfaces, for which they are washed and cleaned of any dirt and grease. The area of the future joint should be degreased (Cosmofen 10 or 60 are suitable) and dried thoroughly.
When wiping the base, it is important to use lint-free rags that do not leave hairs. Next you should proceed as follows:
- squeeze out a little product along the length of the entire seam;
- You cannot rub or smear liquid plastic;
- If possible, the product should be pressed;
- maintain the complete drying time specified in the instructions;
- the position of the parts can only be changed within a few seconds;
- It is necessary to observe the conditions during work - temperature above +5, but not more than 25 degrees, humidity less than 60%.
