Sika® Primer-790

Solvent-based adhesion promoter for non-porous substrates

Sika® Primer-790 is a solvent-based colorless adhesion promoter, which reacts with moisture and deposits active groups on the substrate. These groups act as a link between substrates and adhesives. Sika® Primer-790 is specifically formulated for the treatment of bond faces prior to application of Sikasil® 1- and 2-component silicone sealants and adhesives.
