ELASTOSIL® A 4

ELASTOSIL® A 4 is a carbon dioxide-vulcanizing, solventless, one-component, curable elastomer designed for silk screen applications. It is a moisture-curing material with a very long shelf life. Once ELASTOSIL® A 4 is in place on the substrate, the cure may be induced by exposure to a combination of carbon dioxide and moisture. Adhesion may be improved by mildly preheating the substrate.

Brand: ELASTOSIL (230 products)

Product Type: 1K (1 component) Adhesive, Solvent free (100% Solids) Sealant
