F-300 is a two-part casting polyurethane system which cures to form a 65 Shore D semi rigid plastic. This system offers a 10-12 minute working time with a demould within 3-4 hours at typical ambient temperature. Once cured, this system will offer excellent heat stability. The low mixed viscosity of this system enables the reproduction of fine detail and minimises air bubble entrapment. This system cures white in colour. Advantages – Easy to use 1/1 ratio by weight – Ambient temperature curing – Long working time with fast demould – Fine detail reproduction – Excellent heat stability – Pigmentable – Low Toxicity – Paintable when cured
