Sika Primer 209 D Primer Adhesion promoter for Organic Plastics 250ml

Sika® Primer-209 D is a black solvent-based primer that 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 surfaces to be bonded before the application of Sika one-component polyurethanes. This primer may provide excellent adhesion without prior activation steps on certain plastic substrates.

Sika® Primer-209 D is used to improve adhesion on many plastics and painted surfaces such as GRP, epoxy resins, PVC, ABS, PMMA, PC, PS, and acrylics, alkyd/melamine, powder coatings, and baked paints. Due to the wide variety of plastic materials, it is mandatory to conduct preliminary tests on original substrates under production conditions.

Surfaces must be clean, dry, and free from grease, oil, dust, and contaminants. Adhesion on substrates can be improved by adding and/or combining pretreatment processes such as abrasion, cleaning, and activation. Shake Sika® Primer209 D very thoroughly until the mixing ball moves freely. Continue shaking for another minute and apply a thin but covering layer using a brush, felt pad, or sponge. The ideal application temperature and surface temperature is between 15 °C and 25 °C. Sika® Primer-209 D should be applied only once. Care must be taken to ensure that this single application provides sufficiently dense coverage. Consumption and application method depend on the specific nature of the substrates. Seal the container tightly immediately after each use.
