Sika® Primer-215 is a solvent-based colourless to slightly yellow primer, which reacts with moisture and forms a thin layer. This layer acts as a link between substrates and adhesives.
Sika® Primer-215 is specifically formulated for the treatment of bond surfaces prior to application of Sika’s 1-component Polyurethanes.
Sika® Primer-215 is used to improve adhesion on many plastics and wood such as GRP, epoxy resins, PVC, ABS and timber.
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-215 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.

Sika® Primer-215 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 of product approx. one month after opening if used frequently or after two months in case of infrequent use. 30 ml cans are for single application only.
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.
METHOD OF APPLICATION
Surfaces must be clean, dry and free from grease, oil, dust and contaminants.
Adhesion on substrates might be improved by adding and/or combining pre-treatment processes such as scuffing, cleaning and activating prior the primer application.
Apply a thin but covering coat of Sika® Primer-215 with a brush, felt or foam applicator.
Ideal application and surface temperature is between 15 °C and 25 °C.
Sika® Primer-215 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.
