Hermetic glue is used to seal cracks, waterproofing and thermal insulation of various joints. The pastoral composition is used in filling voids, gluing and sealing seams during repair. Different types of sealants are characterized by the properties and sphere of application. Some are suitable for processing glass or wood, heat -resistant are used as seals for fireplaces.
The qualitative characteristics of the material are determined by the properties of the main component. By the degree of readiness, one -component compositions are distinguished, with which you can work at once, and two -component – involving the addition of a certain substance before applying. There are also non -hardening adhesive compounds and hardening, elastic and plastic.
Silicone sealant is best suited for working with glass, enamel, wood, ceramics. Distinguish neutral and vinegar compositions. Neutral sealant is the most popular in sealing seams, does not provoke oxides. Acetic sealant is more often used for work in rooms, in t. h. bathroom, pool, bath. The material is applied to a low -free and dry surface with a gun or from a tube.
Polyurethane sealants are distinguished by high elasticity. Used in sealing and gluing any materials. Polyurethane sealants are characterized by special strength. The composition is resistant to corrosion, quickly hardens even when it comes into reaction with water. Acrylic sealant is characterized by elasticity and resistance to vibrations and temperature extremes.
