Sika Primer-209 D Black 250ml helps you achieve durable bonds by forming a moisture-activated interfacial layer that links substrates and adhesives. It supports adhesion on a wide range of plastics and paints—including GRP, epoxy resins, PVC, ABS, PMMA, PC, PS, acrylics, alkyds/melamine, powder coatings, and baking varnishes—and is specifically formulated to treat bond faces before applying Sika’s 1-component polyurethanes. In some plastics, it may provide excellent adhesion without prior activation steps. Because performance varies by substrate, always perform substrate-specific tests under actual production conditions and consult Sika for compatibility, especially for materials prone to stress cracking. This product is intended for experienced professional users only.
