GP-675 is a 100% active Nonionic silicone polyol block copolymer with the structure below where the polyoxyethylene (EO) blocks and polyoxypropylene blocks (PO) are random.
The polyoxyethylene-polyoxypropylene copolymer blocks and dimethyl silicone polymer blocks are joined through non-hydrolyzable silicon to carbon bonds. The following list summarizes some of the special features of GP-675:
- Low Surface Tension
- Water Dispersible
- Low Freeze Point
Clear to Slightly Hazy, Colorless to Amber Liquid

GP-675 is designed to function as an emulsifier, wetting agent and profoaming additive for a variety of applications including: polyurethane foams, hard surface cleaners and polishes and cosmetic formulations. GP-675 exhibits inverse solubility versus temperature characteristics, becoming insoluble in water as temperature is increased to approximately 40° C (104° F). This property suggests use as a defoamer for hot aqueous surfactant solutions. The following are some additional applications:
- Pigment Dispersant
- Glass Cleaner Ingredient
- Wetting Agent
- Shampoo Additive
- Thread Lubricant
- Polyurethane Foam (Cell Control Agent)
- Leveling and Flow Control Agent
- Profoaming Additive (Aqueous Systems)
Processing and Safety Guidelines
GP-675 has a very low order of toxicity, but should still be handled with all precautions common to the use of any industrial chemical product. For additional information refer to Safety Data Sheet.
GP-675 is supplied in 5-gallon (40 lbs.) pails, 55-gallon (465 lbs.) drums and 330-gallon (2790 lbs.) totes.. Moisture Sensitive. Keep containers tightly sealed. Store below 100° F.
