The main characteristics of silicone glass resin are hardness and transparency, with a visible light transmittance of over 90%. The film insulation performance after film formation is good, and it has the advantages of friction resistance, heat resistance, aging resistance, radiation resistance, low temperature non brittleness, solvent resistance, hydrophobicity, moisture resistance, non toxicity, and strong transmittance. There is no gas release during use, even under 450 ° C, high vacuum, and electron radiation conditions, no gas is produced.It can also improve the moisture resistance, aging resistance, radiation resistance, and impact resistance of the substrate. Wear resistant hardening coatings can be widely used on various plastic and rubber products, mainly as transparent wear-resistant protective coatings for glass, organic glass, polycarbonate, acrylic plastics, polyurethane, polyamide, polyester, polymethyl methacrylate, polystyrene, polyolefin, polytetrafluoroethylene, silicone resin, silicone rubber, chloroprene rubber, lenses, windshields on airplanes and cars, imitation gold crafts, metallized plastics, playing cards, high-end posters, etc.In addition, due to the lower refractive index of glass resin coating compared to any transparent plastic, the transmittance and optical performance can be improved by reducing the background contrast of transparent plastic.
Wear resistant and hardened glass resin coatings can also be used as insulation and moisture-proof protective coatings for electronic and electrical components such as resistors, capacitors, transistors, etc. The resin can be applied to the surfaces of copper, aluminum, iron, steel, etc. to prevent oxidation and maintain the original metallic luster. It can even be immersed in boiling 5% (mass fraction) sodium chloride, 1% (mass fraction) sodium hydroxide, and 1% (mass fraction) hydrochloric acid without damage; Coating it on a glass plate can improve the impact strength of the glass without compromising transparency; Applying it to paper, pottery, and buildings can provide waterproofing and improve glossiness. Non standard resistors, carbon film resistors, ceramic skeleton resistors, phenolic resin skeleton inductor coils, and polystyrene skeleton inductor coils treated with glass resin all have moisture-proof and insulating effects, stable electrical performance parameters, and particularly outstanding high-frequency performance, meeting technical requirements; And the appearance is bright, smooth, clean and beautiful. In addition, impregnating small transformer coils with glass resin instead of epoxy varnish and silicone insulation paint can avoid poisoning and air pollution caused by benzene solvents when using the above two insulation paints.
Glass resin is soluble in ethanol, butanol, ethyl acetate, benzene, xylene, and ketones, with ethanol being the most commonly used solvent. The usage methods of glass resin include spraying, immersion coating, stick coating, brush coating, vacuum spraying, etc. The thickness of the coating is best between 0.1 and 0.3 mil Omil=25. 4Xl0-6m)， Typically, one pound of glass resin can coat 125 to 135 square feet of substrate. Before use, the surface of the coated substrate should be cleaned to remove impurities and oil stains. Cleaning methods include acid washing, alkali washing, water washing, acetone washing, etc. For certain polymer materials, such as organic glass, polycarbonate, etc., specific surface treatments are required.
