Polytek Poly-Optic® 1411 ES7 Low Viscosity, Polyurethane Casting Resins
Categories: Polymer; Thermoplastic; Polyurethane, TP

Material Notes: Description: Poly-Optic® 14-Series Casting Resins are two-part, polyurethane systems formulated specifically for applications where optical clarity is required. Castings are clear like water; however, PolyColor dyes can be added to obtain clear, colored castings. Poly-Optic systems, with low viscosities and long pot-lives, provide for easy mixing, excellent detail penetration, and easy degassing, through vacuum or pressure casting techniques, for bubble-free castings.

Product Line Features:

  • Crystal clear
  • Reproduces fine detail
  • Can be machined, drilled and sanded
  • Tough and hard, but not brittle
  • Long working time
  • Low shrinkage upon cure
