Sika Deutschland has introduced a new fire retardant epoxy resin system, Biresin CR134FR, into the composites market.
The company say that the new resin system is especially suited for hand laminating visual carbon fibre components but could be used in other applications as well.
Tested at an independent laboratory against UL94, they say that Biresin CR134FR has been given a V-0 rating.
Compared to many fire resistant epoxy resins, Sika claim that this new system is almost transparent, allowing the fibre structure of high value carbon fibre to be seen. Biresin CR134FR, which has a Tg of ~130°C, does not contain any halogenated compounds which can give off harmful gasses when they burn.
