Polycraft FC-6620-C cures water clear, it is ideal for rapid prototyping or where fast pot life and demould times are required. Due to the shore pot life recommended casting thickness is between 1 - 7 mm , casting thicker may result aire bubbles trapped in cast.
FC-6600 / FC-6620 / FC-6630 / FC-6666 Polyurethane resins are not suitable for use with condensation cure silicones such as the GP-3481, these resins must be used with addition cure mould making silicone rubber.
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.
