Chemlok 238 ID Adhesive
Covercoat adhesive for bonding non-polar elastomers
Chemlok 238 ID adhesive is a versatile covercoat adhesive designed to bond a variety of non-polar elastomers to themselves, Chemlok 205 primed metals, and other rigid substrates. Its formulation consists of a blend of polymers, organic compounds, and mineral fillers dispersed in an organic solvent system, providing excellent adhesion and flexibility.
