Product Introduction
BECTRON® Bectron SA 70P1-34 is a white, paste-type silicone adhesive and sealant developed for demanding electronic industry applications. Its strong unprimed adhesion to widely used substrates such as FR4, PBT, aluminium, and copper ensures dependable bonding and sealing performance without the need for surface priming. The paste consistency allows for easy, non-sag application, especially on vertical or uneven assemblies. With a tack-free time of 15 minutes and full cure in 24 hours at room temperature, this material offers both process efficiency and robust long-term performance. BECTRON® SA 70P1-34 combines a Shore A hardness of 34 with high elongation of 580% and tensile strength of 2 MPa—making it an ideal choice for sealing or bonding where mechanical stress, thermal expansion differences, or vibration are present. The product maintains flexibility and adhesion in high-temperature environments up to +200 °C over 20,000 hours of operation.
