Alkoxy neutral one part translucent middle viscosity rtv silicone sealant glue SK-781C for electronics
SK-781C is a good leveling and RTV one-component neutral silicone sealant. It exhibits good adhesion properties to most materials, suitable for electric and electronic devises sealing. At room temperature, curing process is fast and does not generate heat neither corrosive acids by-product. The cured product exhibits wide service temperature range, good electronic properties.
It exhibits the following features1. Release neutral alcohol, no acids.2. Good leveling, Fast tack free.3. Easy to operate; pre-mixing or heating is not required.4. Good adhesion properties to multifarious materials. 5. Good chemical resistance and water-proof.6. Good electronic properties.7. Green environmental materials.
