Introduction of polyurethane sealant
Polyurethane sealant is a sealant whose main components are polyurethane rubber and polyurethane prepolymer.
This type of sealant has high tensile strength, excellent elasticity, abrasion resistance, oil resistance and cold resistance, but it has poor water resistance, especially alkali resistance.
It can be divided into heating vulcanization type, room temperature vulcanization type and hot melt type. Among them, the room temperature vulcanization type is divided into one-component and two-component.
It is widely used in buildings, squares and highways as caulking sealing materials, as well as sealing in automobile manufacturing, glass installation, electronic filling, submarines and rockets.

The product I bought is really good. The other ones I bought before have a lot of particles in it. They are not smooth to the touch. I don’t know how to use it, and the beauty stitches I bought make it. I really don’t have to say.

The smell is very small, the gel is translucent, it is smooth to use, and it dries quickly. The anti-mildew effect needs time to test.
