GENIOPERL® W35 is a polymer modifier with a linear structure based on a functionalized silicone.
GENIOPERL® W35 improves the impact strength of thermoset polymer systems like epoxy- or vinylester resins, especially at low temperatures. We recommend additions of 2 - 8 wt. % for thermosets, in each case relative to the unfilled resin/curing agent or polymer system.
Due to the typically low addition content of GENIOPERL® W35 the viscosity of the uncured resin as well as the glass tranistion temperatures of the cured resins remain almost unaffetcted.
The use of GENIOPERL® W35in cycloaliphatic epoxy resins or epoxy resins cured by carboxylic acid anhydrides is particularly recommended.
GENIOPERL® W35 is incorporated into polymer systems by dispersion in monomer or resin blends prior to curing at temperatures between 50 °C and 80 °C. We recommend processing temperatures of at least 50 °C for optimum dispersion. We also recommend the use of rotor-stator systems or simple blade like stirring systems.
