Product Overview: White-component molding plus high viscosity thixotropic silicone, can be formed by dispensing the desired shape cofferdam. This product is good adhesion, moderate intensity, and a moisture-proof, waterproof, resistant to ozone, radiation, resistance to weathering characteristics. This product is heat-curing curing methods, the cured product not only with glass, metal and other substrates have good adhesion, while integrated with the COB packaging material with excellent adhesion. COB LED package can be used for wall surface light source, PTC's inner bonding, and bonding of various electronic components, bonding, fixed. Features: 1, strong bonding, ceramics, plates and other materials COB bonding firm, lasting adhesion; 2, moderate viscosity, good thixotropy, smoother interface, after dispensing can do not see the contact; 3, good reliability, no poisoning not curing phenomenon.

Packing: product packaging needles SK-903: 50g / support SK-903: 300g / support Note: 1, recommended that the product cryopreservation, 0-10 ℃ save 4-6 months; at room temperature (25 ℃) can be stored for three months. 2, before the package should stand high temperature dehumidifier properly maintain the cleanliness of the bracket; 3. Do not touch the product of nitrogen, phosphorus, sulfur, ethynyl, more vinyl, peroxide and lead, tin, cadmium and other metal compounds, avoid catalyst poisoning affect the curing effect. 4. Before use, please note read product information, product safety labels and packaging materials for safe use.
