  • PU3675

    ALCHEMIX PU 3675 is a low viscosity, two component polyurethane system which can be used to produce patterns, moulds, models and prototypes with excellent fine detail replication. ALCHEMIX PU 3675 can be filled with mineral or metallic fillers for reduced shrinkage, and has rapid demould times even when cast in thin sections. Learn More
  • PU3676

    ALCHEMIX PU 3676 is a low viscosity, two component polyurethane system which can be used to produce patterns, moulds, models and prototypes with excellent fine detail replication. ALCHEMIX PU 3676 can be filled with mineral or metallic fillers for reduced shrinkage, and has rapid demould times even when cast in thin sections. Learn More
  • PU368

    ALCHEMIX PU368 is a two component, odourless fastcast polyurethane system to which specific dry fillers can be added. The high flexural strength of this product ensures that parts with thin sections are very strong and not brittle. Extremely high Tg ensures thermal stability at high temperature. Very low and time stable shrinkage. Learn More
  • PU3691

    ALCHEMIX PU 3691 is an unfilled, no odour, low viscosity two component polyurethane system to which specific dry fillers can be added in either the suggested or variable ratios depending on the application and the required thickness of the casting.  Can be used to produce ultra-fine detail in model-making, or as a low viscosity casting resin for pattern-making. Learn More
