URETHANE PLASTIC - Rigid Plastic

Fastcast / Smooth Cast / Others

• Fastcast Polyurethanes
  The Fastcast series of rigid polyurethane plastics are low viscosity and cure with minimal shrinkage. They have an easy to use 1:1 mix ratio. Fastcast resins are suitable for making negatives, moulds, masters and vacuum forming tools. Fastcast resins can be filled with mineral filler (to limit exotherm and improve machining) or aluminium powder (to improve thermal conductivity).
  
  F16 – fill to 150%, 3 minute pot life
  F18 – fill to 180%, 4.5 minute pot life
  F19 – fill to 360%, 6-7 minute pot life

• Smooth Cast 300
  The Smooth Cast 300 Series of liquid plastics are ultra-low viscosity casting resins that yield castings that are bright white and virtually bubble free. Vacuum degassing is not necessary. They offer the convenience of a one to one mix ratio. These resins readily accept fillers and can be pigmented. Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for Smooth-Cast Liquid Plastics include reproducing small to medium size sculptures, cold cast bronze castings, making prototype models, special effect props and decorative jewelry.

• Smooth-Cast ROTO
  Smooth-Cast ROTO is a low viscosity liquid plastic that gradually becomes thicker, making it ideal for rotational casting applications. Castings will be hollow and lightweight but have the appearance of being solid, allowing you to use less material to attain the same finished look and substantially lowering your material costs. Fully cured castings are semi-rigid and exhibit good impact resistance. Castings resist moisture and mild solvents and can be machined, sanded and painted. ROTO can also be cast solid. So-Strong colour pigments can be used to tint the white plastic.

• Rapid Prototyping Plastics
  This range of specialized urethane resins are designed for prototyping and castings that require plastic type properties.
