Polytek Poly-Optic® 1730 Urethane Resin
Categories: Polymer; Thermoplastic; Polyurethane, TP

Material Notes: Description: Poly-Optic® 17-Series Urethane Resins are two-component, mercury-free, room temperature curing (RTV) systems that are formulated specifically for applications where optical clarity is a must. These polyurethane systems produce water-clear castings, but can be used in conjunction with PolyColor Dyes and dry fillers (e.g., fine metal powders) to create a myriad of effects. 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. Vacuum and/or pressure casting techniques are recommended for bubble-free parts..

Product Line Features:

  • Non-Mercury Formulas
  • Water clear
  • Reproduces fine detail
  • Can be machined, drilled and sanded
  • Low shrinkage upon cure
  • Low Viscosity
  • Easily accepts PolyColor Dyes and dry fillers
