Pigmented, solvent based primer for paints and plastics 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 viscous
|
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 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. Advantages - Gives improved adhesion to paints and plastics
- Low viscous

Technical Information IMPORTANT NOTE Sika® Primer-209 D is a moisture reactive system. In order to maintain product quality it is important to reseal the container with the inner plastic liner immediately after use. Once the surface pre-treatment operation is completed, the cap has to be screwed on.
Dispose the product of approx. one month after opening if used frequently or after two months in case of infrequent use.
If gelling, separation or a significant increase in viscosity is noted, discard the primer immediately.
Never dilute or mix this product with any other substances.
If used on transparent or translucent substrates such as plastics, etc., an adequate UV protection is mandatory.

Application Information METHOD OF APPLICATION Surfaces must be clean, dry and free from grease, oil, dust and contaminants.
Adhesion on substrates may be improved by adding and/or combining pre-treatment processes such as scuffing, cleaning and activating. 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. |
