- Product description
Sika® Primer-507 is based on Purform® technology. Purform® technology enables high performance polyurethane products with less than 0.1% monomeric diisocyanate for improved health and safety. Sika® Primer-507 is a black solvent-based primer that reacts with moisture to form a thin layer (film-forming). This layer acts as a bonding agent between the substrate and the adhesive.
