Chemlok 2332 Adhesive
Covercoat adhesive that bonds rubber compounds to primed metals and other substrates
Chemlok 2332 adhesive is a versatile covercoat adhesive designed to bond a wide variety of unvulcanized or vulcanized rubber compounds to primed metals or other rigid substrates. It also effectively bonds treated textiles to rubber during vulcanization processes. This adhesive is composed of a blend of polymers, organic compounds, and mineral fillers dispersed in an organic solvent system, offering excellent adhesion and durability. Chemlok 2332 is recommended for use over Chemlok 205 or Chemosil 211 primer for optimal performance.

Shelf Life/Storage
Shelf life is nine months from date of manufacture when stored by the recipient below 25 C (77 F) in original, unopened container. Do not store or use near heat, sparks or open flame. Chemlok 2332 adhesive is moisture sensitive. Minimize exposure to moisture by preparing only what is needed for several hours of use.
