SikaForce®-300 Primer is a solvent-based colourless adhesion promoter. The product is specifically formulated for the treatment of bond faces, prior to the application of SikaForce®-301 and SikaForce®-302 plastic repair adhesives. This primer provides good adhesion without previous activation steps on many substrates. Seek manufacturer’s advice and perform tests on original substrates before using the primer on materials prone to stress cracking. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility. SikaForce®-300 Primer has to be applied in a thin and even coat to the surface in short bursts to avoid dripping or running of the primer. If pre-treated area is not bonded within the maximum flash-off time, the pre-treatment process has to be repeated (once only). Consumption and method of application depends on the specific nature of the substrates.
