Chemlok 289/290 Adhesive
Two-part adhesive system for bonding rubber linings to various substrates
Chemlok 289/290 is a two-part adhesive system designed for robustly bonding rubber linings to a wide range of substrates, including steel, stainless steel, aluminum, titanium, and wood. The system comprises a primer (Chemlok 289) and a covercoat (Chemlok 290), each formulated with a blend of polymers, organic compounds, and mineral fillers dispersed in an organic solvent. This sophisticated formulation ensures superior adhesion and corrosion resistance.
