Description
GP-58 is a 100% active organo silicone wax copolymer. This unique product is recommended for use as a lubricant, mold release agent and internal lubricant for plastics. When combined with aliphatic solvents, such as mineral spirits, GP-58 forms a dry, colorless film on substrates. This film is stable and will not break down in the presence of water. The lack of any dimethyl silicone removes the problems of orange peel, fisheyes, or similar effects normally associated with dimethyl silicone. GP-58 has the following special features:
- Acts as an Antiblocking Coating when Applied to Uncured Rubber Product
- Unique Silicone Copolymer Provides Excellent Metal on Metal Lubrication
- Acts as a Rubber and Plastic Mold Release Agent Lubricant

Processing and Safety Guidelines
GP-58 may be converted to a solvent based product by first melting the wax, and with stirring, adding to a solution of mineral spirits. A stable 10% active product can be made this way. Note - use caution with flammable or combustible materials. GP-58 may also be blended with other Genesee Polymers' silicone fluids for use as internal processing aids in the rubber manufacturing industry. For safety requirements, refer to Safety Data Sheet.
Packaging/Handling/Storage
GP-58 is supplied in 5-gallon (16 kg.) pails and 55-gallon (177 kg.) drums. No special storage is required.
