Shin-Etsu KE-3450 One-Component Flame Retardant Liquid Silicone Rubber Adhesive Sealant
Shin-Etsu KE-3450 is a one-component room-temperature curing liquid silicone rubber adhesive sealant developed by Shin-Etsu Chemical. It uses a one-component condensation curing system, which reacts with moisture in the air after dispensing and cures at room temperature without heating equipment. KE-3450 provides excellent flame resistance (UL94 V-0), electrical insulation, heat resistance, cold resistance and weather resistance. It is suitable for fixing and sealing electronic components such as circuit boards and power adapters. The product reduces low molecular weight siloxanes that may cause electrical contact problems. It also provides excellent adhesion to various substrates and is non-corrosive to metals, making it suitable for reliable electronic and electrical applications.
