GP-219 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. GP-219 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. Some of the special properties of GP-219 are listed below:
- Low Surface Tension
- Excellent Lubricity
- Chemically Inert
Clear to Hazy, Colorless to Straw Liquid

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. Other applications include the following:
- Wetting Agent
- Leveling and Flow Control Agent
- Thread Lubricant
Processing and Safety Guidelines
GP-219 has a very low order of toxicity, but should still be handled with all precautions common to the use of any industrial chemical product. Consult Safety Data Sheet for additional details.
GP-219 is supplied in 5-gallon (40 lbs.) pails, 55-gallon (460 lbs.) drums and 330-gallon (2760 lbs.) totes. Moisture Sensitive. Keep containers tightly sealed. Store below 100° F.
