Organic Silicone
Silicone resin is bonded by silicon-oxygen bond with high bonding energy (Si -O-Si), the layer has various properties such as heat resistance, weather resistance, electrical insulation, and water resistance.
Methyl silicone resin: It is a silicone resin whose organic substituent is completely composed of methyl groups. It can form a coating with very high hardness, moisture resistance, insulation, water resistance and mold release
Methyl/phenyl silicone resin: It is a silicone resin whose organic substituent consists of methyl and phenyl. Can form a coating with excellent heat resistance, mechanical strength and gloss.
Organic resin modified silicone resin: it is a silicone resin mixed with other organic resins. Coating with resin characteristics.
Apply
(1) Heat-resistant coating: silicone resin, using its heat resistance, Adopted as a paint in a temperature range (200°C or higher) that cannot be used with general organic resin-based paints. In addition, because of its excellent weather resistance and water resistance, it has the characteristics of strong resistance to outdoor deterioration and high affinity with ordinary inorganic pigments. Heat-resistant coatings come in a variety of products depending on their application, material, temperature range, etc. Among them, silicone resin is widely used in many products.
Extended use: iron, rice cooker, pot, oven, water heater, kettle, Around the engine, heating device, exhaust muffler, plant equipment
(2) Weather-resistant coating: The deterioration of the external coating is caused by ultraviolet light, high temperature , water and other reasons, luster weakening and weathering will occur. Silicone resin is not decomposed by ultraviolet light, high temperature, water, etc., so it has extremely excellent weather resistance compared with ordinary organic resins, and is used as a letdown for exterior paint.
(3) For resin modification: silicone containing a large number of phenyl groups The resin has excellent compatibility with other organic resins and can impart various silicone properties. For example, flame retardancy can be imparted by adding KR-480 or the like during kneading for producing polycarbonate. From the standpoint of environmental protection and safety, it is attracting attention as a material replacing conventional antimony-based, halogen-based, and phosphorus-based materials.
(4) Electrical insulation coating layer: Silicone resin at room temperature ~200℃ It maintains a high level of volume resistivity above 1X10^13 Ω·cm in a wide temperature range, showing excellent electrical insulation properties with small temperature dependence. In addition, due to the direction of the methyl group on the surface of the coating, it has excellent low water absorption, and these features are widely used in the protection of various electronic components
(5) Adhesives for heat resistance and electrical insulation: use of silicone resin It is excellent in heat resistance and electrical insulation, and because it is not softened by heat, it is used as a binder for moldings such as metal powder. Recently, with the popularization of solar cells and HV and EV vehicles, the demand for its use as an adhesive in coil molding is also increasing.
