Contact adhesive: description and application

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 isolated.

general description

The principle of operation of the described composition is that after application of the mixture, the solvent begins to evaporate for a short time, while the polymer solidifies. This provides the most durable connection. In the production process, in order to achieve a change in the initial grindability and increase of tackiness, other components are added by the type of rosin and resin.

Positive characteristics

Contact glue is often used in furniture production for the reason that it does not promote the swelling of chipboard chips. The material guarantees instant gluing due to the short drying time. It contains an organic mixture of polychloroprene, as well as synthetic rubber, which provides a stable, maximum durable and durable bonding of all kinds of materials such as ceramics, concrete, wood, leather, fabric and other.

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 the possibility of using the product in a day, while the hot method implies the possibility of operation after six hours. Before gluing, the surface must be dust-free, degreased and well dried. For preparation, you can use gasoline and solvents. Composition is not required to be mixed before use. It should be applied in a thin, even layer on both glued parts. The contact adhesive will show an excellent result if, for some time, the glued surfaces are held in such a way that they are under some pressure. Strength will depend precisely on the applied impact. The master should know that the contact glue is flammable, it belongs to class A1.

Varieties of brands

Contact super-glue is produced under different brands, each of which has certain characteristics. As the base one can distinguish dry residue, viscosity and open time. The more impressive is the dry residue, the less amount of solvent has been added during manufacture. The more significant is the dry residue, the smaller the volume of the solvent and the less odor. From the type of solvent that was used in the manufacture, the degree of fire safety, as well as toxicity, will depend. The open time is determined by the volatility of the solvents. This parameter is the period during which the open layer of the composition applied to the substrate is able to maintain the ability to bond.

The most volatile, more precisely, easily evaporated, are solvents like hexane or acetone. As their negative features is a low flash point. If the super-glue has a lot of easily evaporating solvent, which is saturated with room air, even an accidental spark can cause a fire.

Additional features

Contact adhesive for PVC does not harden after application within a few minutes, during this period it retains stickiness. This factor allows you to change the position of the product, which is convenient for final position adjustment. The product is convenient in storage, since it is presented in a closed sealed vessel, in which it does not solidify. After its application, the product can be used at a high and extremely low temperature. Range of operation varies from -40 to +50 degrees. The contact adhesive for plastic is resistant to acids, alcohol, alkali and water solutions.

Characteristics of contact glue "Moment Classic"

If you are interested in contact universal adhesives, then we recommend choosing "Moment Classic". It is suitable for bonding materials in various combinations, it can be PVC, wood, leather, felt, plastic, ceramics, porcelain, glass and so on. However, you can not use this compound to glue the dishes that are supposed to be used for food.

What is important to know about the classic glue "Moment"

In everyday life, this adhesive composition is used quite often, since it is reliable and versatile. Among other things, it is resistant to water. You can buy glue in a package, the volume of which varies from 30 to 750 milliliters. Do not buy a product, from the date of manufacture which has passed more than 24 months. To preserve the original properties should be stored at a temperature of -20 to +30 degrees. However, if the composition was frozen, then it is able to restore the original consistency and property, for this it is important to ensure the conditions of room temperature.

Description of contact glue "Moment Crystal"

This kind is intended for gluing hard and soft polyvinylchloride, plexiglass, polystyrene, etc. You can glue various combinations of materials, which were mentioned above. Among others, one can not help but mention cardboard, paper and metal, as well as rubber. The composition is clear and water resistant. This polyurethane mixture should be applied to surfaces that are previously sanded with a sandpaper. The resulting adhesive seam exhibits resistance to heat, weak alkali and acid solutions, and to aging.

General description of the "Moment" for rubber

It is intended for gluing all varieties of foamed and hard rubber. The latter can be combined with rigid 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 is from -30 to +100 degrees.
