Water-swelling sealant is a kind of polyurethane variety non-stereotypes paste which is one-component and solvent-free. So it is also called one-component polyurethane water-swelling sealant. And it is used in the sealing structural joints. It has two sealing and waterproof mechanisms, which make it play a key role in waterproofing. It has the elasticity of rubber and swells encountering water to fill the joint when water enters into the joint. The unique advantages make water-swelling sealant have[...]

Liquid polysulfide rubber as the basic material, adding tackifying resin, vulcanizing agent, accelerant and fortifier makes up the two-component polysulfide sealant (double-component polysulfide sealant). It is a kind of two-component sealant that can vulcanize and crosslink by itself at room temperature. Its appearance is exquisite and even paste or ropy liquid, so it is also called two-component polysulfide sealing paste. It is made up of A component and B component. A component is hoary even paste[...]

Polyurethane rubber and the prepolymer of polyurethane are the main components of polyurethane sealant. Polyurethane sealant can be divided into three kinds: heating curing polyurethane sealant, room temperature vulcanized polyurethane sealant and hot melt polyurethane sealant. And the room temperature vulcanized polyurethane sealant is divided into two kinds: one-component polyurethane and two-component polyurethane sealant. Two-component polyurethane sealant (double-component polyurethane sealant)[...]

One-component polyurethane sealant is a kind of sealant that is one-component and cures at room temperature. The paste state makes it be squeezed out to operation. One-component polyurethane sealant cures by absorbing the moisture in the air. And it reacts with active group in the surface to play the adhesion role. It is not saggy, so it will not flow when used in vertical joints. It can adhere on metal, rubber, wood, cement, ceramic and glass. It has two functions: sealing and waterproofing. And[...]
