Poly 1512, 1512X, 1511 Casting Resin - All Kit Sizes

  • $75.00

Important! Polytek is discontinuing a lot of resin formulas and 1511 is one of them. That said, 1512X and 1512 are sure to follow. Here are some offsets that work as well or better:

  • TC-804 - 6-7 Min. Work Time, may be used instead of 1512X or 1511.
  • TC-808 - ~2 min. Work Time, may be used instead of 1512X.
  • BR-75D - 10-12 Min. Work Time, Brushable Resin For Mother Molds.

Poly 1512 is a 1:1 mix, low viscosity, polyurethane liquid casting plastic with exceptional strength and impact resistance. Cured 1512 exhibits similar properties to ABS plastic. 1512 resin is great for casting tough, thin-walled parts, coating Styro-foam, and creating light-weight mother molds.

1512 is available in 3 set times:

  • 1512X - 5 Min. working time and ~1 Hr. demold
  • 1511 - 10 Min. working time and 4-5 Hr. demold
  • 1512 - 20 Min. working time and 16-20 Hr. demold

Poly 1512 can be poured to produce decorative objects, production parts, prototype parts, tools, models, duplicate masters, patterns, and more. The high physical properties of this plastic make it ideal for making models and prototype parts that simulate thermoplastics such as ABS and polypropylene. White in color. Can be accelerated for faster demold using Poly 15 Part X catalyst. Can be color cast using PolyColor Pigments.

Important! Slow formulas, like 1512 and 1511 are more susceptible to contamination by ambient humidity. Slow formulas wotk best in very dry areas and climates. 1512 is not recommended for use in very humid areas as the moisture in the air can cause bubbles in the cured resin.

For professional use only. Use in a well ventilated area.

Poly 1512 can also be mixed with PolyFiber II thickener to create a thixotropic (paste-like) consistency for making lightweight plastic mother molds or mold shells. You can find 15X, PolyFiber thickener, and PolyColor pigments in our polyurethane additives section.
