Popular Specifications

800 cps | 85-90A Shore Hardness

Formerly RenCast 6403-3. Ideal for durable parts such as impellers, rollers, gears and wheels. Features low viscosity, fast cure, high tensile strength and good load recovery. Cast thickness is limited to 0.5.

Please note that two 5 gallon pails of hardener are required per each 5 gallon pail of resin to provide the correct mix ratio.

Due to discontinuation of a raw material, changes have been made to the old formula. Information on this change can be found here. Our testing has found the new version to be functionally identical. Please contact our technical services department for further information or clarification.

NOTE: May be thickened to use as a surface coat using Freeman 1060 Hardener as a third component. Please see the Technical Bulletin "Procedure for Surface Coat Application" for instructions.
