Sika Primer-207 is a black, moisture curing liquid primer specifically formulated for the treatment of bond faces prior to application of Sika polyurethane adhesives and sealants. This primer may provide excellent adhesion without previous activation step on many substrates. Sika Primer-207 combines reduced flash-off time and fast adhesion built-up. Sika Primer-207 fluoresces under long-wave UV light.
Sika Primer-207 is used to give improved adhesion in adhesive bonding applications on a very broad range of different substrates such as float glass, ceramic-coated glass, plastics, pre-coatings, painted surfaces, E-coats and metals. This product is suitable for experienced professional users only. Tests with actual substrates and conditions, especially boundary temperature conditions have to be performed to ensure adhesion and material compatibility.
