ELASTOSIL® A 4

ELASTOSIL® A 4 is a carbon dioxide vulcanizing, solventless, one component, curable elastomer designed for silk screen applications. ELASTOSIL® A 4 is a moisture curing material with a very long skin-over time. 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.
