Xencast P2 Fast Cast Polyurethane Casting Resin

Xencast® P2 is an easy-to-use fast-cast polyurethane resin system capable of producing highly detailed castings which can be demoulded within around 10-20 mins. Its unique formulation has been developed to offer the best possible results across a wide range of applications including miniatures, figures, models, patterns, sculptures, prototypes and production parts.

P2 has been formulated for maximum reliability and so requires no degassing and no other specialist equipment. Its low viscosity and modified flow properties result in superior surface detail with minimal air entrapment.

Xencast® P2 pu casting resin is compatible with a wide range of mould materials, fillers, pigments and additives making it the perfect all-purpose casting resin whilst the fast cure time reduces waiting and increases productivity.

Whether you're new to casting or a seasoned professional you're sure to get excellent results with this highly regarded resin system.

Typical Uses

In conjunction with a suitable mould, Xencast® P2 fast cast resin can be used to all manner of cast parts including beautifully detailed figurines, RPG miniatures, models, patterns, prototype parts, foundry patterns, sculptures, fishing lures, ornaments and architectural features.

With the addition of ATH filler powder, Xencast® P2 can also be used to reproduce large sculptures, whereas the addition of metal powders and pigments makes it possible to 'cold cast' bronzes and other authentic-looking metallic castings.

Advantages

• Fine surface detail reproduction with minimal air entrapment
• No degassing necessary
• Fast de-mould time (around 20mins)
• Very easy to use - compatible with most mould materials
• Easily pigmented
• Supports a high ratio of filler

How to Buy

The resin is available in a choice of 1kg, 2kg and 4kg kits, each containing the correct ratios of Part A and Part B.

The 2kg kit is also available as part of the Xencast Resin Casting Starter Kit.

Considerations

• Very Short pot-life of just over 2 minutes means you must work quickly
• Not a toughened system so less suitable for more structural applications

Compatibility Information - Dos and Don'ts

Although by no means an exhaustive list, the mould materials, pigments and additives listed below have all been tested and are known to work well with Xencast® P2.

• Compatible Moulds
• Condensation/tin cure RTV silicone rubber
• Addition/platinum cure RTV silicone rubber
• Polypropylene and polyethylene mould 'trays'

• Compatible Pigments
• Polyurethane Colour Pigment (for vivid opaque colours)
• Translucent Tinting Pigment (for less vivid opaque colours)
• PearlEx® powder pigments

• Compatible Fillers
• All dry filler powders
• All metal powders (for realistic cold castings)
• Photoluminescent (glow in the dark) powders

Xencast® P2 should not be cast into latex rubber moulds. Although P2 has a good moisture tolerance it is still recommended to avoid moulds or substrates which may harbour excessive levels of moisture.

Key Processing Information

• Ease of Use
• For hobby or professional use (always follow SDS advice).

• Odour
• P2 is almost odourless.

• Safety Precautions
• Wear gloves and goggles and work in a well ventilated area. Always read the SDS before use.

• Ambient Conditions
• Can be used from 10 to 30°C although pot-life and cure time will be affected significantly. For small or thin-section castings an ambient of 20-25°C is required.

• Degassing
• Not necessary. Low viscosity and special flow profile will result in excellent surface finish and minimal air entrapment without degassing.

• Mix Ratio
• Mix 'Part A and 'Part B' 1:1 by weight. Use digital scales.

• Mixing
• Mix thoroughly by hand for around 1 minutes.

• Pot-Life
• 2 mins 15 seconds. Be sure to pour your casting(s) before this time.

• Exotherm (Over-Heating)
• Resin will heat-up whilst it cures. Large mouldings will require a filler. Once mixed, pour resin immediately.

• Thin Sections
• Suitable for fine detail. Minimum section thickness is 0.5mm.

• Maximum Volume
• Maximum castable volume for unfilled resin depends on mould shape and material but is approx. 6cm³ in the 'thickest' areas.

• Cure Time/Demould
• Larger/thicker castings will heat up more and cure quicker (around 10-15mins). Small castings or thin sections will take longer (around 20mins).

• Pigments and Fillers
• A wide range of pigments and fillers (including metal powders) can be added to change the properties and appearance of castings.

• Shelf Life
• Minimum shelf life is 12 month under room conditions (18 - 25°C), when stored in original un-opened containers.
