Polyurethane casting resin which cures straight to white. Has a 150 second pot life but a lower viscosity compared to standard G27

SKU: G27W Category:


PolyCast G27 White Polyurethane Casting Resin is a very low viscosity, fast curing two-part resin which sets straight to white.

Each 2kg Polycast Kit contains 1kg of resin and 1kg of hardener. These are mixed in equal measures and then poured into a mould of an original item. The resin cures, forming a robust and accurate plastic replica of the original coloured white.

Scale model makers use G27 White to create reproductions of masters they have sculpted from epoxy putty or kit parts which have been modified.

Resin artists use G27 White to copy items from original work, including jewellery, figurines and other artefacts. Industrial users replicate machine parts with G27 White, avoiding the repetitive task of fabricating new components or prototypes.

Parts made using PolyCast Casting Resins have very low shrinkage and do not sag or distort with heat. As a result, Polycast Resins are renowned and trusted for their high detail and repeatability.

G27 White has a pot life of 150 seconds, enabling casts to be produced quickly. It has a de-mould time of 20 minutes to 10mm thickness. It has a lower viscosity compared to the standard Polycast G27 Resin which is available in either beige or grey. For further information, please consult the data sheet.

For resin colours other than white, SylCreate have the facility to custom make resins colour-matched to a specific Pantone or RAL colour.

If you require customisation, please contact SylCreate via email with the full Pantone or RAL Colour Reference number for a quote. Alternatively, oil-based or dry pigments can be added by the user to colour the resin.

For those new to the casting and moulding process, you can find instructions in our Showcase article How to make and use a two-part silicone mould for resin casting. There is also a video available under the Videos tab on this product page.

  • Creating multiple copies of original and modified scale model parts
  • Making resin art and pieces of jewellery
  • Reproducing parts as an alternative to individual machining or injection moulding

Can I use pigments to colour my resin?
Yes. Both oil-based and dry pigments should be fine for colouring resins. We recommend that you mix a small amount of resin with your pigments first to test the compatibility. Water-based pigments should not be used.
