To date, there are a lot of types of sealant, and all of them are classified according to several signs and rules. First of all, you can distinguish a group in which all collected sealants will be completely ready for use:
– One -component (they are ready for use almost immediately). – Two or more component (they require careful and accurate mixing of components before use).
Recently, polyurethane sealants began to be quite popular, and it was they who will now be given attention.
What is polyurethane sealants?
Polyurethane sealants are an elastic adhesive mass created on a polyurethane basis, and it can maintain its elasticity for a sufficiently large amount of time. This sealant can be used for gluing completely different materials, for example, wood, metal, stone, plastic, ceramics and other common materials.
It is worth noting that polyurethane sealants have the most beautiful qualities that provide the opportunity to make this material suitable for use for a long time.
Speaking more accurately that modern high -quality polyurethane sealants are characterized by the following properties:
– They have incredibly good resistance to corrosion. – Polymerization occurs under a certain effect of wet air, but at the same time there is a creation of a strong and high -quality seam, which has excellent sealing. – Materials are completely resistant to ultraviolet radiation, they are not amenable to the effects of salts, acids and various cracks.
