Product Introduction
Momentive SNAPSIL™ TN3305 Silicone Adhesive Sealant is a one-component, low volatile siloxane silicone that cures at room temperature under atmospheric moisture. Supplied as a flowable material in clear, white or black, it develops primerless adhesion to many substrates and cures to an elastic rubber with good electrical insulation properties. With fast tack-free behavior, low odor and non-corrosive performance, SNAPSIL™ TN3305 is suitable for a wide range of electronic and industrial sealing and bonding uses.
