Polycraft FC-6630 is a water clear semi flexible polyurethane potting and casting resin which cures to a Shore A 55 rubber. It is ultra low viscosity has been specially formulated for potting, for rapid prototyping or embedding of any type when clear casting is required without vacuum. It can be easily pigmented with suitable polyurethane pigments. UV stable.
FC-6600 / FC-6620 / FC-6630 / FC-6666 Polyurethane resins must be used with addition cure mould making silicone rubber and are not suitable for use with condensation cure silicones such as the GP-3481.
This is a professional polyurethane casting system and as such certain procedures must be adhered to to ensure successful curing. The resins and moulds must be used at a temperature of 20°c - 25°c , if used at temperatures below this cure may be inhibited. Brittle casts and uncured amounts of resin are all indicators that the resin and moulds have not been at correct temperature. We always recommend purchasing a small kit for testing before purchasing larger amounts.
Applications include :
Clear casting, embedding, model making, resin casting, jewellery making.
