Genesee Polymers' GP-219 SILICONE POLYOL COPOLYMER is a 100% active polyoxyethylene modified dimethylpolysiloxane block copolymer.GP-219 is not water soluble because of the low content of polyoxyethylene in the copolymer. The indicated value of HLB (Hydrophile/Lipophile Balance) of 8.4 suggests use of GP-219 as an emulsifier for water in oil emulsions (w/o), or as a pigment dispersant for thermoplastics or solvent-based coatings.GP-219 SILICONE POLYOL COPOLYMER contains no reactive functional groups and is chemically inert. The silicone and polyoxyethylene block polymer components of GP-219 are joined through Silicon to Carbon bonds, insuring resistance to breakdown through hydrolysis.
