Polytek 15-Series Liquid Plastics

Features & Benefits

• Easy 1A:1B mix ratio by weight

• Tough and hard, but not brittle
• Lightweight for mold shells
• Low shrinkage upon cure
• Fast-setting and slower-setting options

Poly 15-Series Liquid Plastics are high-quality casting resins used for decorative objects, production parts, tools, models, patterns, fixtures, duplicate masters, and mold shells. These versatile materials offer excellent detail reproduction and durability, making them ideal for a variety of applications.

Poly 1511, 1512, and 1512X have the feel and density of wood or thermoplastics. When mixed with PolyFiber II, they create tough, lightweight mold shells.

Poly 15-3 and 15-3X are dense, mineral-filled plastics with low shrinkage, making them ideal for rigid applications.

For water-clear, non-yellowing plastics, consider Poly-Optic® 14-Series.

For spray applications, consider the EasyFlo Series.

Curing & Demolding

• Allow castings to remain in the mold until fully cured to prevent deformation.
• Pre-warmed molds can speed up the curing process.
• Thin castings take longer to cure than thicker ones.
