What is Polyurethane Sealant

Polyurethane sealant is a sealant with polyurethane rubber and polyurethane prepolymer as main components. This kind of sealant has high tensile strength, excellent elasticity, abrasion resistance, oil resistance and cold resistance, but water resistance, especially alkali water resistance is not good. Can be divided into heating vulcanization type, room temperature vulcanization type and hot melt type three. Among them, room temperature vulcanized type has one-component and two-component. It is widely used in buildings, squares and highways as sealing materials for embedded joints, as well as in automobile manufacturing, glass installation, electronic filling, submarines and rockets.

Material characteristics of Polyurethane Sealant
Polyurethane sealant has the following characteristics: excellent abrasion resistance; low-temperature flexibility; wide range of adjustable performance; high mechanical strength; good adhesion; good elasticity, excellent restorability, can be suitable for dynamic joints; good weather resistance, service life of up to 15 to 20 years; excellent oil resistance; biological aging resistance; moderate price.
Classification of Polyurethane Sealant
Polyurethane sealant is generally divided into two basic types, one-component and two-component, one-component moisture-curing type, two-component reaction-curing type. One-component sealant construction is convenient, but slow curing; two-component fast curing, good performance characteristics, but the use of the need to formulate, the process is more complex. Both have their own development prospects.
