Description
GP-1070 is a 100% active Nonionic silicone polyol block copolymer consisting of polyoxyethylene blocks (EO) and dimethyl silicone polymer blocks that are joined through non-hydrolyzable silicon to carbon bonds.
GP-1070 is soluble in lower alcohols (EtOH, IPA) and dispersible in water, along with aliphatic and aromatic hydrocarbons. The following list summarizes some of the special features of GP-1070:
- Low Surface Tension
- High Lubricity
- Contains Primary Hydroxyl Groups

Applications
GP-1070 is designed to function as an emulsifier, wetting agent and profoaming additive, especially for use in polyurethane foams, hard surface cleaners and polishes and cosmetic formulations. In addition, GP-1070 contains a primary hydroxyl group at each end of the molecule, allowing for reaction with isocyanates in polyurethane resin systems. This is expected to improve flow and leveling of polyurethane coatings and impart non-stick characteristics to the cured coatings. GP-1070 is an ideal additive to polyurethane systems for increasing hydrophobicity.
GP-1070 can function as a fiber lubricant and fabric softener, exhibiting good adhesion to synthetic threads--especially polyester, making it an ideal choice for textile applications that require the thermal stability and high lubricity that silicones provide. The following are some additional applications:
- Pigment Dispersant
- Glass Cleaner
- Fabric Softening
- Cosmetic Emulsifier
Processing and Safety Guidelines
GP-1070 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.
