Sika Primer-206 G+P Black Bonding Primer

Sika® Primer-206 G+P is a pigmented, solvent-based black primer that reacts with moisture to form a thin layer linking substrates and adhesives. It is designed for experienced professionals treating bond faces before applying Sika's 1-component polyurethanes.

This easy-to-apply primer improves adhesion on substrates such as float glass, ceramic-coated glass, pre-coatings, painted surfaces, and some plastics and metals. As with Sika's other primers, preliminary tests on original substrates under production conditions are recommended, especially on materials prone to stress cracking.
