Poly-Optic® 1411 & 1411 ES7 Casting Resins

poly-optic-1411-1411-eS7Poly-Optic® 1411 & Poly-Optic® 1411 ES7 are 1A:1B by volume mixes, water-clear, hard, polyurethane casting plastics that are great for making clear parts that look like water or glass. PolyColor Dyes can be added to these resins to produce colored, transparent castings. They can also be filled with a variety of dry fillers to achieve varying looks.

Poly-Optic 1411 ES7 is a very long pour time (~7 hours!) version of Poly-Optic 1411 and is designed for large pours where increased working time and slow gelling/curing is required to minimize part distortion.

Using pre-warmed molds hastens demold time, reduces shrinkage and improves the overall quality of the casting.

NOTES: Vacuum and/or pressure casting techniques are recommended for these products. 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.
