Sika® Primer-209 N
Sika® Primer-209 N is a solvent-based black primer, which reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesives.
Sika® Primer-209 N is specifically formulated for the treatment of bond faces prior to application of Sika’s 1-component Polyurethanes. This primer might provide excellent adhesion without previous activation step on certain plastic substrates.
