GENIOPERL® W36 improves the impact strength of thermoset polymer systems, 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.

GENIOPERL® W36 contains internal anti-foam additives to reduce foam formation by using the material in vacuum casting processes.

The use of GENIOPERL® W36 in cycloaliphatic epoxy resins or epoxy resins cured by carboxylic acid anhydrides is particularly recommended.

GENIOPERL® W36 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.

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
