Sika Primer-209D

Sika® Primer-209 D is a solvent-based, black 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 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.  

Usage:

• Sika® Primer-209 D is used to improve adhesion on many plastics and paints such as GRP, epoxy resins, PVC, ABS, PMMA, PC, PS, 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. Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.  

Application:

• Shake the Sika® Primer-209 D can very thoroughly until mixing ball rattles freely. Continue shaking for another minute and apply a thin but covering coat with a brush, felt or foam applicator.
• Ideal application and surface temperature are between 15 °C and 25 °C.
• Sika® Primer-209 D has to be applied once only. Care must be taken to ensure that this single application gives adequately dense coverage. Consumption and method of application depend on the specific nature of the substrates. Tightly reseal container immediately after each use.
