Chemlok 6253 Adhesive
One-coat adhesive bonding elastomers to metals
Chemlok 6253 is a versatile, one-coat adhesive designed to bond a wide variety of elastomers to various metal substrates. Its formulation, comprised of polymers, organic compounds, and mineral fillers dispersed in an organic solvent, ensures strong adhesion and excellent resistance to harsh environments. When used as a two-coat system, it provides even greater protection.
