Polycast G28 is a low viscosity casting resin with a pot life of 7-8 minutes and a de-mould time of 2 to 3 hours to 10mm
PolyCast G28 Polyurethane Casting Resin is a low viscosity two-part resin with a longer pot-life which makes it suitable for casting master and core models in medium to large moulds.
PolyCast resins are ideal for reproducing parts from a single master in small production runs, as an alternative to injection moulding or individually machined parts.
Parts made using Sylmasta casting resins have very low shrinkage and do not sag or distort with heat.
As a result, Sylmasta casting resins have been trusted by professional kit builders and industrial users for years for their high detail and repeatability.
They also have a very low odour, unlike traditional polyester resins. Each 2kg Polycast pack contains 1kg of resin and 1kg of hardener. For those wanting to buy in bulk, a 10kg kit featuring 5 x 2kg packs is available.
Polycast G28 cures to a light beige colour (Original). Eight other colours – black, white, red, blue, yellow, brown, green and grey – are available as standard.
For G28 Casting Resin that is custom made to order and coloured matched to a more specific Pantone or RAL colour, please see our G28 Coloured Casting Resin.
We sell a range of accessories which are used in the casting process, including monoject syringes and mixing cups. You can find these in the Casting & Mould Making Accessories section of our website.
