GT-5051Y Organosilicon three-proofing agent
This product is a one-component fluorescent self-drying paint, which is very convenient to use. Good insulation performance. It has good transparency, strong adhesion, fast curing speed, excellent weather resistance and excellent electrical properties. The PCB circuit board has the properties of anti-salt spray, moisture-proof, mildew-proof, weak acid and alkali, alcohol, and strong adhesion. Even if the coating layer is very thin, the coating paint can maintain its good effect. The conformal coating is widely used in the automotive industry, electronic industry, navigation, household appliances and so on. Completely different from the resin three-proofing agent, it does not absorb moisture under high temperature conditions, does not whiten, and the drying time is fast. It can be dried naturally or dried.
The main products include: electronic silicone rubber series, epoxy resin series, electronic three-proofing agent series, thermal conductive silicone grease series, electronic adhesive series, flux, insulating agent and other electronic chemical material series products.
