Sika® Primer-210 is a colorless to slightly yellowish solvent-based primer that reacts with moisture to form a thin layer (film-forming). This layer acts as a bonding agent between the substrate and the adhesive.

Sika® Primer-210 has been specially developed for the pretreatment of bonding surfaces in combination with Sikaflex® adhesives.
