GENIOPERL® W35
GENIOPERL® W35 is a polymer modifier with a linear structure based on a functionalized silicone. It is used mainly as a toughening additive for epoxy resins and composites.
Properties
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.
Cured thermoset materials containing GENIOPERL® W35 show increased mechanical impact strength and fracture toughness and also much higher resistance to thermally induced stress.
Due to the typically low addition content of GENIOPERL® W35 the viscosity and the curing kinetics of the uncured resin as well as the glass tranistion temperatures of the cured resins remain almost unaffetcted. The modulus of the cured resin is only slightly affected by addition of GENIOPERL® W35.
The addition of GENIOPERL® W35 to e.g. epoxy based coating or adhesion formulations wil improve the adhesion strength as well as the impact resistance of the respective coatings significantly.

Application details
The use of GENIOPERL® W35 in 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.
