In use, Sika Aktivator-100 Clear enables quick, reliable surface activation where non-porous materials meet primers, sealants, or adhesives, helping achieve strong initial grip and durable bonding over time. Its transparent formulation ensures there is no visual interference with bonded assemblies, making it suitable for applications on glass, screen-printed ceramics, and pre-treated surfaces of older polyurethane systems. Always consult the manufacturer and conduct substrate-specific tests to confirm adhesion and material compatibility.
