Key features
Water Resistance –Silicone resins,especially those having methyl groups, form films with excellent water repellency.
Electrical Insulation –high dielectric strength and low conductivity make silicone resin excellent for insulating coatings and electronic applications.
Weather Resistance – Strong resistance to UV, ozone, and oxidation ensures long-term durability outdoors without yellowing, chalking, or cracking.
Heat Resistance – Stable silicon–oxygen bonds allow continuous use at 200–300 °C, with short-term tolerance of even higher temperatures without decomposition.
Chemical Resistance –acids, bases, and many solvents are resisted, maintaining stability in chemically aggressive environments.
Automotive – Used in impact-resistant coatings for car floors and components, offering excellent flexibility, water repellency, and surface durability
Industrial Coatings – Functions as a one-component silicone oligomer coating agent with high gloss and crack resistance, ideal for protective and decorative finishes on metal and inorganic surfaces
Electronics – Can be applied as a surface treatment resin for insulating and moisture-resistant coatings on electronic parts due to its thermal and dielectric properties
Construction Materials – Suitable for water-repellent treatment of concrete, stone, and other porous substrates, preventing staining and improving longevity
General Manufacturing – Acts as a resin modifier to enhance flexibility, weatherability, and heat resistance in various industrial resin systems
