14-Series plastics are specifically designed for applications where optical clarity is a must. Castings will be water-clear; however,PolyColor Dyescan be added to obtain clear, colored castings. In addition, Poly-Optic systems can be filled with metal, marble and many other fine powders to achieve myriad 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.

There isNEW Mercury-Free Formulationnow available:Poly-Optic®1490 Clear Casting Resin

NOTES:Vacuum and/or pressure casting techniques are recommended for these products (pressure casting or vacuum casting equipment is required for Poly-Optic®1490).Cure inhibition canoccur when casting thisresin inTinSil®tin-cured silicone rubber molds use aPlatSil®platinum-cured silicone rubber moldif working with silicone mold rubbers.Polyurethane mold materialscan also be used, but a release agent is required (e.g.,Pol-Ease®2300 Release Agent).

Two-part, aliphatic polyurethane resins

Easily acceptsPolyColor Dyesand dry fillers

Can be machined, drilled and sanded

Non-yellowing formulas (except Poly-Optic

14-70); however, not recommended for long-term exterior use. Can be sealed with a UV-stable clear coat and/or UV Additive can be added to the lqiuid mixture for longer outdoor use.

This casting resin cures to a water-clear, virtually unbreakable Shore D80 plastic. Cure Poly-Optic 1410 at room temperature, and for optimum physical properties, post cure at 150F.

Poly-Optic 1411 cures to a super strong, water-clear, D80 plastic. Poly-Optic 1411 develops hardness and can be demolded sooner than Poly-Optic 1410. It also has a higher heat deflection temperature, which is useful in certain prototyping applications.

1411 Casting Resin designed for thicker/larger volume castings.

Poly-Optic 1412 is a high-strength, higher heat resistant temperature, fast-curing, rapid-prototyping, clear plastic designed for casting in heated molds.

This casting resin cures to a tough, impact- and heat-resistant, water-clear plastic that can be polished and machined. For strong plastic, heat cure at 150-180F. A brittle, glass-like, breakaway material can be made for special effects applications when left to cure at room temperature (only recommended for casting thicknesses of 0.5).

This casting resin cures to a firm, water-clear rubber with a Shore hardness of A70. Blend Poly-Optic 1410 and Poly-Optic 14-70 to achieve any hardness between Shore D85 and Shore A70

with an easy 1A:1B mix ratio by volume (100A:90B by weight). Must be pressure cast or used with vacuum casting equipment (not vacuum degassing).

*Demold time varies with thickness of casting and the amount of accelerator used.


UsePoly-Optic 14 Part X Acceleratorto increase the speed of curing.

AddPoly-Optic 14 Part R Retarderto slow the cure of Poly-Optic products. Recommended when casting over 0.5 thickness.

PolyColor Dyescan be used to color Poly-Optic 14-Series plastics. They are available in Black, Brown, Blue, Green, Red, Yellow, and a White and Fleshtone Pigment.

UseUV Additiveto help reduce the onset of chalking and pitting of Poly-Optic products for exterior applications.

UsePolyPurge Aerosol Dry Gasto extend product life by spraying it into containers before resealing.
