Applications
GP-146 is a release agent for the following industries:
- Rubber Molding
- Plastic Molding
- Urethane Molding
- Epoxy Molding
GP-146 is also recommended for use as a textile lubricant.
Processing and Safety Guidelines
For optimum efficiency, GP-146 should be diluted with solvent prior to application to molds. This helps insure that over application of release agent is avoided. Dilution solvents include aliphatic and aromatic solvents (water-free). Recommended application methods include brushing, swabbing, spraying, and dipping. The silicone polymer used to formulate GP-146 can, as with many release agents, cause painting and adhesion problems if over applied, or if not properly cleaned from molded parts prior to finishing operations. If preliminary tests show that finishing problems may result from the use of GP-146, wash parts with solvent or detergent and rinse with clean water before painting or adhesive bonding. For safety information, refer to Safety Data Sheet.
Packaging/Handling/Storage
GP-146 is supplied in 5-gallon (40 lbs.) pails, 55-gallon (440 lbs.) drums and 330-gallon (2640 lbs.) totes. To insure stability, containers must be kept tightly sealed when not in use. GP-146 reacts with moisture. When product is transferred from its original container, be sure it is kept free from water.
