Contact adhesive has a wide range of uses; it most often contains two main components. Among them, synthetic rubber and a volatile solvent can be distinguished.
general description
The principle of operation of the described composition is that after applying the mixture, the solvent begins to evaporate within a short time, while the polymer solidifies. This provides the most durable connection. In the production process, other components such as rosin and resin are added to achieve a change in initial setting and tackiness.
Positive characteristics
Contact adhesive is often used in furniture production for the reason that it does not contribute to swelling of chipboard chips. The material guarantees instant bonding due to the short drying time. It contains an organic mixture of polychloroprene, as well as synthetic rubber, which provides stable, maximum strength and long-lasting bonding of all kinds of materials such as ceramics, concrete, wood, leather, fabric and others.
Recommendations for use
Contact adhesive involves the use of one of two methods of application, among them cold and hot technologies can be distinguished. The first provides for the possibility of using the product in a day, while the hot method implies the possibility of operation in six hours. Before gluing, the surface must be dusted off, degreased and dried well. For preparation, you can use gasoline and solvents. The composition does not need to be mixed before use. It must be applied with a thin even layer on both parts to be glued. Contact adhesive will show excellent results if the adhesive surfaces are held for some time so that they are under some pressure. Strength will depend precisely on the applied impact. The master must know that contact adhesive is flammable, it belongs to class A1.
Varieties of brands
Contact super-glue is available under different brands, each of which has certain characteristics. As a base, you can select the dry residue, viscosity and open time. The more impressive the dry residue is, the less solvent was added during manufacture. The more significant the dry residue, the smaller the volume of solvent and the less the smell. The degree of fire safety, as well as toxicity, will depend on the type of solvent used in the manufacture. Open time is determined by the volatility of solvents. This parameter represents the period during which the open layer of the composition deposited on the base, is able to maintain the ability to stick.
The most volatile, or rather, easily volatile, are solvents like hexane or acetone. Their negative features are low flash point. If super-glue has a large amount of easily evaporating solvent, which is saturated with the room air, then even a random spark can cause a fire.
Extra features
Contact adhesive for PVC does not harden after application within a few minutes, during the specified period it retains stickiness. This factor allows you to change the position of the product, which is convenient for the final regulation of the place. The product is convenient to store, as it is presented in a sealed sealed vessel in which it does not harden. After its application, the product can be used at high and extremely low temperatures. The range of operation varies from -40 to +50 degrees. Contact adhesive for plastic is resistant to acid, alcohol, alkali and aqueous solutions.
Characteristics of Moment Classic contact adhesive
If you are interested in contact universal adhesives, we recommend that you select "Moment Classic". It is suitable for gluing materials in various combinations, it can be polyvinyl chloride, wood, leather, felt, plastic, ceramics, porcelain, glass and so on. However, you can not use this composition for gluing dishes, which are supposed to be used for food.
What is important to know about the classic moment glue
In everyday life, this adhesive is used quite often, since it is reliable and versatile. Among other things, it is characterized by resistance to water. You can buy glue in a package, the volume of which varies from 30 to 750 milliliters. You should not buy a product from the date of manufacture of which more than 24 months have passed. To preserve the original properties, storage should be provided at temperatures from -20 to +30 degrees. However, if the composition was subjected to freezing, then it is able to restore the original consistency and property, for this it is important to ensure room temperature conditions.
Description of Crystal Moment Contact Adhesive
This variety is intended for bonding hard and soft polyvinyl chloride, plexiglass, polystyrene, etc. You can glue various combinations of materials that were mentioned above. Among others, cardboard, paper and metal, as well as rubber, should be noted. The composition is transparent and water resistant. This polyurethane mixture should be applied to surfaces that are pre-sanded. The resulting adhesive joint is resistant to heat, weak solutions of alkalis and acids, and also to aging.
General description of the "Moment" for rubber
Designed for bonding all types of foamed and hard rubber. The latter can be combined with hard PVC, wood, concrete, metal and other materials. The composition is characterized by resistance to frost, as well as heat resistance. The mixture can be operated at a wide temperature range, which ranges from -30 to +100 degrees.
