KingSeal Primer PU is a low viscosity single component solvent based moisture cure polyurethane primer especially formulated to significantly enhance the adhesion of polyurethane and polysulphide sealants with the most common porous and nonporous construction substrates.
Applications
KingSeal Primer PU is used to enhance the bond between polyurethane and polysulphide sealants and the substrates in the following applications:
High porous substrate such as normal grade concrete, mortar and red bricks
Impervious substrates such as aluminum, steel and glass
Rubber and asphalt surfaces
KingSeal Primer PU should be overcoated with the sealant while still tacky to achieve optimum adhesion strength
Advantages
Significantly improves the adhesion of polyurethane and polysulphide sealants over several construction substrates such as concrete, asphalt, galvanized steel, aluminum and glass
Increases the service life of the sealing system
Easy to use, single component product that does not need mixing
