GP-596 is a 30% active epoxy functional silicone polymer in solution. The epoxy functionality in GP-596 allows for rapid cross linking with standard amine curing agents. Selecting the proper curing agent is dependent on application techniques, pot life requirements, cure conditions and physical properties needed. Cured coatings formed from GP-596 exhibit greater elongation, higher impact resistance and more flexibility than coatings formed from standard bisphenol A type resins. This increased flexibility allows for greater adhesion to coated surfaces, resulting in improved durability. In addition to the tough coating properties of GP-596, the presence of the unique silicone-epoxy copolymer imparts non-stick and rust inhibiting characteristics as well. This strongly suggests applications involving protection of ferrous and nonferrous metals exposed to extreme abrasion conditions, or corrosive atmospheres. The following list summarizes some of the special features of GP-596: 

  • Forms Highly Adhesive Flexible Coatings

  • Acts as a Rust Inhibitor
  • Forms Clear, Cured Films
  • Abrasion Resistant
  • Excellent Bonding

Processing and Safety Guidelines

GP-596 may be formulated with pigments, thickeners, dispersants and other additives as needed to yield finished coatings. The technology of formulating is closely related to standard epoxy resin coatings applications. The following is one of the suggested curing systems:


  • 100 parts GP-596 Epoxy Functional Silicone Solution
  •  6.18 parts Ancamine 1617 Curing Agent (Air Products & Chemical, Inc.; Allentown, PA)

This mixture may be applied by spraying, dipping or brushing. Applied films will cure completely in 2 - 7 days at room temperature, or four hours at 105° C. Use proper precautions needed for handling coatings containing flammable solvents. Catalyzed solutions of GP-596 and curing agent have a limited pot life. The handling of GP-596 involves the use of flammable solvents (toluene, isopropyl alcohol), which present certain hazards in use. Consult Safety Data Sheet for additional details.


GP-596 is supplied in 5-gallon (40 lbs.) pails and 55-gallon (430 lbs.) drums. Observe safe conditions common to storing Flammable Materials. Do not store near fire or flame. Moisture Sensitive. Keep containers tightly sealed. Do not weld or cut drums, even when empty.
