Contact adhesive has a wide range of uses, it most often contains two main components. Among them are synthetic rubber and a volatile solvent.
General Description
The principle of operation of the described composition is that after applying the mixture, the solvent begins to evaporate for a short time, while the polymer hardens. This ensures the most durable connection. In the production process, in order to achieve a change in the initial setting and increase stickiness, other components such as rosin and resin are added.
Positive Features
Contact adhesive is quite often used in furniture production for the reason that it does not contribute to chipboard chip swelling. 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, extremely strong and durable bonding of various materials such as ceramics, concrete, wood, leather, fabric and more.
Recommendations forapplication
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 after six hours. Before gluing, the surface must be dedusted, degreased and dried well. For preparation, you can use gasoline and solvents. The composition does not need to be mixed before use. It should be applied in a thin even layer on both parts to be bonded. Contact adhesive will show excellent results if the surfaces to be bonded are held for some time in such a way that they are under some pressure. Strength will depend on the applied impact. The master should be aware that the contact adhesive is flammable, it belongs to class A1.
Varieties of stamps
Contact super glue is available under different brands, each of which has certain characteristics. The basic values are dry residue, viscosity and open time. The more impressive the dry residue, the less solvent was added during manufacture. The greater the dry residue, the lower the volume of solvent and the less odor there will be. The degree of fire safety will depend on the type of solvent that was used in the manufacture, andalso toxicity. The open time is determined by the volatility of the solvents. This parameter represents the period during which the exposed layer of the composition applied to the base is able to maintain its ability to bond.
The most volatile, or rather, easily evaporating, are solvents like hexane or acetone. Their negative features are the low flash point. If the super glue has a large amount of volatile solvent in the room air, then even an accidental spark can start a fire.
Additional Features
PVC Contact Adhesive does not harden after application for several minutes, during this period it remains tacky. This factor allows you to change the position of the product, which is convenient for the final adjustment of the place. The product is convenient in storage, as it is presented in a closed hermetic vessel, in which it does not harden. After its application, the products can be used at high and extremely low temperatures. The operating range varies from -40 to +50 degrees. Plastic contact adhesive is resistant to acid, alcohol, alkali and aqueous solutions.
Characteristics of contact adhesive "Moment Classic"
If you are interested in universal contact adhesives, 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 more. However, this composition should not be used for gluing dishes that are supposed to be used for food.
What is important to know about the classic Moment glue
In everyday life, this adhesive composition is used quite often, as 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 that has been more than 24 months from the date of manufacture. To preserve the original properties, storage should be ensured at a temperature of -20 to +30 degrees. However, if the composition has been subjected to freezing, then it is able to restore its original consistency and property, for this it is important to ensure room temperature conditions.
Description of contact adhesive "Moment Crystal"
This variety is intended for bonding hard and soft PVC, plexiglass, polystyrene, etc. Various combinations of materials mentioned above can be bonded. Among others, it is impossible not to mention cardboard, paper and metal, as well as rubber. The composition is transparent and waterproof. This polyurethane mixture must be applied to surfaces that have previously been sanded. The resulting adhesive line is resistant to heat, weak solutions of alkalis and acids, as well as to aging.
General description of "Moment" for rubber
Designed for bonding all kinds of foam 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 ranges from -30 to +100 degrees.
