Poly-Optic 1411 Clear Casting Resin

Polytek

  • $318.00


Poly-Optic 1411 Clear Casting Resin is a two-part, liquid polyurethane resin that cures (RTV) to a water-clear, Shore D80 plastic. This product has a simple 1A:1B mix ratio by volume.

Vacuum and/or pressure casting techniques are recommended for this product. Cure inhibition can occur when casting this resin in tin-cured silicone rubber molds – use a platinum-cured silicone rubber mold if working with silicones.

WARNING: This product contains Phenylmercuric acetate (CAS 62-38-4) chemicals known to the State of California to cause reproductive harm. For more information, go to www.P65Warnings.ca.gov

Notes: 
Demold time varies with thickness of casting and the amount of Poly-Optic Part X Accelerator added. The thinner the casting, the longer the demold time. Shrinkage in polyurethane resins is caused by gelling while hot then cooling. Parts that cure with minimal temperature rise (exotherm) exhibit minimal shrinkage. For additional physical property specifications, refer to the Physical Properties Bulletin.
