KR-220L is a solid silicone resin that crosslinks rapidly upon heating to form cured materials with excellent solvent resistance and no thermal softening. It exhibits near non-combustibility with minimal smoke generation due to its high residual scorching heat. The resin adheres strongly to inorganic substrates such as mica, making it suitable for demanding insulation and coating applications. As a solid resin, users have flexibility in solvent selection, and it can be diluted with organic solvents like toluene, xylene, and alcohol. 

• 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.

• Electronics – Used as a binder and coating resin for electrical components, offering excellent insulation, heat resistance, and flame retardancy

• Industrial – Serves as a high-temperature binder for sintered metal powders and inorganic materials in manufacturing processes

• Powder Metallurgy – Acts as a heat-curable binder in forming molded parts from metal powders, ensuring structural integrity and thermal durability

• Resistor Coatings – Applied in resistor paints to provide thermal stability and reduce smoke generation during operation

• Flame-Retardant Coatings – Used in high-performance coatings requiring low smoke emission and near non-combustibility

• Microwave and Heating Appliances – Suitable as a bonding resin for mica laminates in devices like toasters, irons, and microwave ovens due to its excellent adhesion and heat resistance
