Insoluble in water
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
Non-Hydrolyzable
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
Chemically inert, non-hydrolyzable, active polyoxyethylene modified dimethylpolysiloxane block copolymer. Used as an emulsifier for water in oil emulsions and as a pigment dispersant for thermoplastics and solvent-based coatings. Can be used as a wetting agent, as a leveling and flow control agent and a thread lubricant. Contains low content of polyoxyethylene and no reactive functional groups. Offers low surface tension and very good lubricity.
