Poly 15-Series Liquid Casting Plastics
Poly 15-Series plastics are versatile, two-part polyurethane systems used in countless commercial, industrial, tooling, prototyping, craft, prop and master making applications.
Some of these pourable, room-temperature curing resins mimic the density of thermoplastics (e.g., ABS) or wood. Others are great options for constructing lightweight mold shells, composites, or master models.
Using Poly 15-Series casting resins offer a cost savings up front compared to the expensive tooling costs associated with metal molds required for injection-molded thermoplastic parts.
These plastics can be colored with PolyColor Dyes, mixed with metal powders (e.g., bronze powder) and they can be filled with a variety of inexpensive fillers to conserve cost and reduce shrinkage in large masses.
Poly 15-Series plastics can be cast in PlatSil® and TinSil® silicone molds without any release agent and can be cast in polyurethane rubber molds and latex molds with the proper release agent (e.g., Pol-Ease® 2300 Release Agent).

|Product||Description||Shore Hardness||Mixed Viscosity||Mix Ratio||Pot Life||Demold Time*||Color|
|Poly 15-3 Liquid Plastic||Poly 15-3 has the lowest exothermic temperature when curing which results in the least shrinkage on cure compared to other Polytek plastics. This pre-filled system is also an economical option for master plugs and parts.||D80||2,000 cP||1A:1B by weight||15 min.||12-16 hr.||Tan|
|Poly 15-3X Liquid Plastic||This is the fast version of Poly 15-3.||D80||2,000 cP||1A:1B by weight||5 min.||1-12 hr.||Tan|
|Poly 1511 Liquid Plastic||On cure, this plastic has superior strength properties and the feel and density of hard wood or thermoplastics. When mixed with PolyFiber II, a thickening agent, it is a great option for making tough, lightweight mold shells.||D71||400 cP||1A:1B by weight||10 min.||1-16 hr.||White|
|Poly 1512 Liquid Plastic||On cure, this plastic has superior strength properties and the feel and density of hard wood or thermoplastics. Popular for thin-walled prototype parts molded under pressure.||D71||400 cP||1A:1B by weight||22 min.||1 – 16 hr.||White|
|Poly 1512X Liquid Plastic||This is the fast version of Poly 1512. Very popular option for the construction of brush-on mold shells and casting detailed prototype parts.||D71||400 cP||1A:1B by weight||5 min.||30 min. - 4 hr.||White|
*Demold time varies with thickness of casting and the amount of accelerator used.

|Accelerator||Use Poly 15 Part X Accelerator to increase the speed of curing.|
|Color Dyes||PolyColor Dyes can be used to color Poly 15-Series plastics. They are available in Black, Brown, Blue, Green, Red, Yellow, and a White Pigment.|
|Thickeners||Use PolyFiber II to thicken the liquid mix for application by brush or trowel.|
|Bronze Powder||Create cold cast bronze parts by adding bronze powder at the proper ratio.|
|Neutral-Density Filler||Add PolyFil ND (neutral density) to reduce the cost of 15-Series castings and to help reduce shrinkage in larger castings without affecting density.|
|Product Life Extender||Use PolyPurge Aerosol Dry Gas to extend product life by spraying it into containers before resealing.|
