RenCast 6400-3 is ideal for making flexible molds that can be stripped from parts having undercuts or backdraft. This product can also be cast as resilient parts and pads. It is very flexible and offers high tear resistance. This material can be cast up to 2" thick.

RenCast 6400 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.

Formula Change Information:
Due to discontinuation of a raw material, the RenCast 6400-2 formulation has changed to RenCast 6400-3. 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.
