Fastcast Unfilled Resin

Category Archives: Fastcast Unfilled Resin

Alchemix Unfilled Fastcast Polyurethane Resins offer the customer the ability to use the resin without filler or allows you to add a filler powder at a ratio to suit a specific application. The benefit of this is that it reduces the cost of the overall mix. There are also slowcast versions available for casting bulk items.

Description
PU 3604
ALCHEMIX PU 3604 is an unfilled, no odour, low viscosity two component polyurethane system to which mineral and metallic fillers can be added at variable ratios depending on the application and the required thickness of the casting. ALCHEMIX PU 3604 has excellent physical properties, most notably excellent impact resistance. ALCHEMIX PU 3604 is available as a standard cure speed version (7 - 9 minute pot life) or as a fast cure speed version (2 - 3 minute pot life). The product is pigmented black, but is available in other colours on request.
PU 363
ALCHEMIX PU363 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.
PU 364
ALCHEMIX PU364 is a two component, low odour, fastcast polyurethane system which is designed for thin sections or casting to 20mm thick. The material has a very quick demould time and is designed to be used unfilled.
PU 3641
ALCHEMIX PU 3641 is an odourless two component polyurethane system which is designed for thin sections, or castings up to 20mm thick that require quick demould times. ALCHEMIX PU 3641 is ideally suited for use in rotocasting applications.  
PU 3641S
ALCHEMIX PU 3641S is an odourless two component polyurethane system which is ideally suited for use in rotocasting applications. ALCHEMIX PU 3641S is designed for thin sections, or castings up to 20mm thick that require quick demould times.  
PU 3642
ALCHEMIX PU 3642 is an odourless two component polyurethane system which is designed for thin sections, or castings up to 20mm thick that require quick demould times.  
PU 365
ALCHEMIX PU 365 is an unfilled, two component polyurethane system to which specific mineral and metallic fillers can be added at variable ratios depending on the application and the required thickness of the casting. ALCHEMIX PU 365 can be used to produce patterns, moulds, models and prototypes. ALCHEMIX PU 365 can be cast into dental alginate.
PU 3652
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.
PU 3670
ALCHEMIX PU 3670 is an unfilled, no odour, low viscosity two component polyurethane system to which mineral and metallic fillers can be added in either the suggested or variable ratios depending on the application and the required thickness of the casting. ALCHEMIX PU 3670 can be used to produce ultra-fine detail in model-making, or as a low viscosity casting resin for pattern-making.
PU 3672
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.
