Classification
Polysulfide sealant is a two-component reaction curing material, composed of A and B components. Component A is a milky white or light yellow paste, and component B is a black paste formed by mixing and dehydrating a curing agent and auxiliaries. After curing, it has certain elasticity and adhesion.
