GP-226 is a 100% active polyoxyethylene (EO) modified dimethylpolysiloxane block copolymer. GP-226 is water-dispersible and resistant to breakdown by hydrolysis due to the presence of stable Si - C bonds between silicone and polyol block sections. Some of the special properties of GP-226 are listed below:

  • Low Surface Tension
  • Water Dispersible
  • Non-Hydrolyzable
  • Low Freeze Point
