Chemlok 6254 Adhesive
One-coat adhesive for bonding rubber to metal
Chemlok 6254 is a one-coat adhesive designed for bonding rubber compounds to metal substrates in applications demanding heat and oil resistance. The adhesive comprises a blend of polymers, organic compounds, and mineral fillers, all dissolved or dispersed within an organic solvent system. It offers excellent adhesion and corrosion resistance, particularly when used with mechanically or chemically treated cold-rolled steel or aluminum.
