Polytek Poly-Optic 1411 Clear Casting Plastic


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.

Mix Ratio: 1A / 1B by Volume 100A: 90B by Weight Shore Hardness: D80
Cured Color: Water Clear
Mixed Viscosity: 600 cP

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 SDS and TDS

Physical Properties
Poly-Optic resins are the plastics of choice for mimicking glass and ice-like features and are widely used to create stunning prototypes (lenses, bottles, containers), as well as unique art, medical models, sculpture and display items.
