STC Gun Grade Polysulfide sealant is a two component polysulphide based sealant for expansion joints. It consists of a `Base' compound and `accelerator' when the two components are mixed together prior to application, a firm, flexible rubber like seal with excellent adhesion to concrete, masonry, wood. It is used for construction, expansion & contraction joint application to seal the joint as it has excellent tensile modulus, elongation, bonding, UV & ozone resistance and waterproofing durability. Theproduct is particularly recommended for sealing horizontal structural expansion joints in most civil engineering structures like building superstructures, subways, basements, floors, etc.
