Poly LiteCast Liquid Plastic

casting plastic with wood-like densityPoly LiteCast is a 1A:1B mix, polyurethane liquid casting plastic for making rigid and lightweight decorative moldings, tools, models, patterns, fixtures, duplicate masters, mold shells and more. It is often used as a lightweight casting alternative to plaster and concrete.

Poly LiteCast has a density similar to wood. It drills, sands and machines very readily (contains no silica fillers).

Features

  • Reproduces fine detail
  • Can be machined, drilled, sanded (contains no silica)
  • Great for millwork/molding, décor, props and more
  • Can be colored with PolyColor Dyes
  • Add PolyFiber II for brush-on or trowel application
  • Lightweight alternative to plaster and concrete

 

For a lightweight, machinable polyurethane plastic with slightly more flexibility than Poly LiteCast, consider Poly Plasti-Flex Casting Resin.
