Sika Primer-215 is a colorless to slightly yellow solvent based 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 treating surfaces to be bonded prior to the application of one-component Sika polyurethanes.i.
FIELDS OF APPLICATION
Sika Primer-215 is used to improve adhesion on many plastics and wood such as GRP, epoxy resins, PVC, ABS and wood. Due to the wide variety of plastics, it is mandatory to carry out 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 only suitable for experienced professional users. To ensure adhesion and material compatibility, it is necessary to perform tests with the substrates under real conditions.i.
METHOD OF APPLICATION
Surfaces must be clean, dry and free from grease, oil, dust and contaminants. Adhesion to substrates can be improved by adding and / or combining pre-treatment processes such as abrasion, cleaning and activation prior to primer application.
Apply a thin but covering layer of Sika Primer-215 by brush, felt pad or sponge. The ideal application and surface temperature is between 15 C and 25 C. Sika Primer-215 only needs to be applied once. Care must be taken to ensure that this single application gives sufficiently dense coverage. Consumption and method of application depend on the specific nature of the substrates. Hermetically reseal the container immediately after each use.zzo.
