RTV2 Sealing Silicone Rubber is viscous, transparent liquid with low viscosity, and belongs to two-component addition cure silicone rubber. After mixing the part A and part B at a mix ratio of 1:1, it cures at room temperature or by heating and becomes gel-like elastomer. This silicone rubber is used for the surface of poly-carbonate (PC), PP, ABS, PVC and metal, etc. The curing reaction does not generate heat or any by-products.
Part A: a non-toxic and odorless liquid in transparent color with platinum inside
Part B: a non-toxic and odorless liquid in transparent color.
1.The data are based on the operation under room temperature of 25 °C.
2. The data-sheet of viscosity, hardness, working time, curing time can be adjusted according to your requirements.
D83 Series is tin cure, D82 Series is platinum cure

Electronic potting compounds silicone rubber material is a kind of flowing liquid, and it consists of two components, part A and part B.
1. Preparing: Clean up the coating surface, remove the rust, dust, oil dirt.
2. Pouring: Weigh the silicone part A and part B correctly by 1:1, mix silicone part A and part B thoroughly, pour onto the electronic components/surface after vacuum degassing.
3. Curing: Room temperature cure or heat-up cure are both workable.
4. It should be used up after opening the package, the material must be kept in a cool place sealed well, and it should avoid from contact with moisture in the air.
