SiSiB® SR8040

SiSiB® SR8040 is a solvent-free, pure-methyl silicone resin that blends seamlessly with organic resins. It delivers exceptionally high hardness, superior mechanical resilience, and excellent chemical and weather resistance. Its high SiO₂ content also produces far less smoke during initial heating compared with resins containing higher levels of organic substituents.

Application


  • SiSiB® SR8040 is a pure methyl silicone resin that is easily soluble in organic solvents and quickly gels upon heating to form a low smoke, high ash network structure with excellent thermal stability, weatherability and electrical insulation.


  • SiSiB® SR8040 can be used as a powder coating binder/co-binder, an impregnant for porous substrates or a tack-free prepreg matrix in a wide range of applications from high temperature electrical appliances and exhaust pipe coatings to insulating composites for aerospace and electrical applications.

Packing and Storage


SiSiB® SR8040 is available in 20Kg or 50Kg fiber drum.


SiSiB® SR8040 can crosslink or self-condense in the presence of moisture, making it essential to avoid moisture exposure before final application.


SiSiB® SR8040 Silicone Resin has a shelf life of 12 months from the date of manufacture when stored in its original, unopened containers at or below 25°C (77°F). After opening, containers should be tightly sealed to prevent contamination and moisture from entering the product.
