Genesee Polymers GP-179

Genesee Polymers' GP-179 SILICONE RESIN is a 100% active ethoxy-functional methyl silicone resin, which is suggested for evaluation, as a reactive intermediate, in the synthesis of silicone-organic copolymers for protective coatings.GP-179 will slowly undergo hydrolysis and condensation to a cured resin film when exposed to atmospheric moisture, providing a water repellent protective coating for wood, masonry and metal substrates.When required, GP-179 SILICONE RESIN may be diluted with aliphatic or aromatic hydrocarbon solvents, or with dry alcohols, esters or other solvents.

Safety & Health

Processing and Safety Guidelines
  • GP-179 SILICONE RESIN is combustible (ethyl alcohol is released on contact with atmospheric moisture) and must be handled with all precautions common to handling combustible materials. Use only in well ventilated areas designated for combustible materials handling, and avoid any prolonged exposure to solvent vapors. Make sure no sources of ignition are present.
