Description
GP-214 is a high molecular weight copolymer of silicone and polyol blocks, which is designed to act as a surface active agent in both aqueous and non-aqueous systems. GP-214 contains polyoxyethylene-polyoxypropylene copolymer adducts to a polydimethyl-siloxane backbone, with silicone to polyol segments joined by non-hydrolyzable silicon to carbon bonds. GP-214 is dispersible in water and shows solubility or dispersibility in a wide range of hydrocarbon and chlorinated hydrocarbon solvents. GP-214 contains no functional groups and is chemically inert with a low degree of toxicity. Some of the special properties of GP-214 are listed below:
- High Viscosity
- Non-Hydrolyzable
- Low Freeze Point

Applications
GP-214 is recommended for evaluation as a profoaming additive in plastisol and organosol formulations and in polyether type polyurethane foams. Other suggested applications include:
- Pigment Dispersant
- Wetting agent
- Internal Lubricant (Plastics)
- Thread Lubricant
- Polyrethane Foam (Cell Control Agent)
- Leveling and Flow Control Agent (Solvent Coatings)
- Cosmetics
Processing and Safety Guidelines
GP-214 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.
