RJ-8901AB belongs to the addition curing type of silicone liquid adhesive, which is composed of A and B components. Before curing, as a good liquid flow, it can be through dispensing, pouring. After heating curing molding, and form a very soft gel.
RJ-8901AB thermo-curing sealant has excellent electrical performance, resistance to high and low temperature (-50℃~200℃), waterproof and moisture-proof properties, and has the characteristics of light weight and environmental protection, suitable for the sealing and bonding of electronic circuits, plastic or metal structural parts, wire and cable joints.
