Sika Primer-210 is a colorless and 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-210 is specifically formulated for the treatment of surfaces to be bonded prior to the application of one-component Sika polyurethanes.i.
FIELDS OF APPLICATION
Sika Primer-210 is used to improve adhesion on many metals such as aluminum, steel and non-ferrous metals. This primer could also be used to improve the adhesion of Sikasil sealants and adhesives. Seek manufacturer's advice and perform tests on original substrates before using Sika Primer-210 on materials subject 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.li.
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-210 using a brush, felt pad, clean lint-free cloth or sponge. Sika Primer-210 exhibits thermoplastic behavior up to 3 days after application, therefore high temperatures or initial stresses on the surface to be bonded must be avoided. The ideal application and surface temperature is between 15 C and 25 C. Sika Primer-210 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.izzo.
