Sika Primer-209 D
Sika Primer-209 D 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-209 D 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 certain plastic substrates.
- Gives improved adhesion to paints and plastics
- Low viscosity
Sika Primer-209 D is used to improve adhesion on many plastics and paints such as GRP, epoxy resins, PVC, ABS, PMMA, PC, PS and acrylics, alkyds/melamine, powder coatings, and baking varnishes.
Due to the wide variety of plastics, it is mandatory to perform preliminary tests on original substrates under production conditions. Seek manufacturer’s advice and perform tests on original substrates before using Sika® Primer-209 D on materials prone to stress cracking.
This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.
