Product Introduction
BECTRON® Bectron SA 70P9-60 is a high-strength, black silicone adhesive and sealant in paste form, developed for precision bonding and sealing tasks in the electronic industry. It features excellent unprimed adhesion to key materials such as FR4, PBT, aluminium, and copper, ensuring secure and long-lasting assembly integration. Its paste consistency allows for precise, non-sag application across a range of surfaces. With an exceptionally fast tack-free time of just 3 minutes and full cure within 24 hours at room temperature, this product supports efficient production workflows. BECTRON® SA 70P9-60 combines a high Shore A hardness of 60 with moderate elongation of 200% and a strong tensile strength of 2.35 MPa, offering robust mechanical stability in environments exposed to stress and high temperatures up to +200 °C over 20,000 hours.
