Overview
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
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
