Polyurethane Resin
Polyurethanes are versatile materials that can be tailored for many different applications. A wide variety of hardness, cure speeds, viscosities, mechanical and thermal properties are possible. Alchemie manufacture an extensive range of two component polyurethane systems for applications such as vacuum casting, RIM casting, clear casting, model making and tooling.

PU363
ALCHEMIX PU 363 is a two component, low odour fastcast polyurethane system which contains no hazardous solvents with a quick demould time, good flow properties, and excellent surface detail and finish. Learn More -
PU365
ALCHEMIX PU 365 is an unfilled polyurethane casting system for the manufacture of patterns, moulds, models and prototypes. ALCHEMIX PU 365 can be cast against wet or damp substrates such as dental alginate and can be filled with mineral or metallic fillers for reduced shrinkage. Learn More -
PU3652
ALCHEMIX PU 3652 is an unfilled two component polyurethane system, which has no odour and very low viscosity. Mineral and metallic fillers may be added to it in variable ratios depending on the casting thickness. This economical casting resin can be used to produce ultra-fine details in model making or as a low viscosity casting resin for pattern making. ALCHEMIX PU 3652 is recommended for use in open moulds.

PU3672
ALCHEMIX PU 3672 is an unfilled, no odour, low viscosity two component fastcast 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 -
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 -
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 -
PU3720
ALCHEMIX PU 3720 is a machine-mixed polyurethane paste system that is particularly suitable for the manufacture of design / styling models, master models or parts requiring high strength combined with low density. The product is thixotropic and cures quickly, allowing the rapid build-up of layers and the printing of parts with overhanging sections. The cured material can be easily machined or worked with hand tools to give a smooth surface finish. Printing parts using ALCHEMIX PU 3720 gives a significant reduction in waste when compared to traditional methods. Learn More
