Sika Primer 207 AGR 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 207 AGR 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 many substrates. Sika Primer 207 AGR fluoresces under long-wave UV light for a limited period of time. This feature is used for in-process control. For professional use only.
