Product Introduction
Momentive SNAPSIL™ TSE322 is a one-component, heat-curable silicone adhesive sealant that provides primerless adhesion to many substrates. Available as a light blue (TSE322) or black (TSE322-B) flowable material with self-leveling properties, it offers a long working time at room temperature and cures rapidly at elevated temperatures. Once cured, SNAPSIL™ TSE322 delivers excellent dielectric performance, non-corrosive bonding, low shrinkage and reliable mechanical strength over a wide temperature range.
