Crystic 344A

Halogen and Antimony Free, Fire Retardant Polyester Resin


Crystic 344A is a polyester resin, containing styrene and methyl methacrylate. It is designed to be used as a filled system, in the manufacture of fire retardant laminates.


Crystic 344A was developed primarily for use in rolling stock applications. It is, however, suitable for internal applications in other areas of the land transport, marine and building industries where a very high degree of fire resistance and exceptionally low smoke and toxic gas generation is required.

Features & Benefits

Crystic 344A is a halogen and antimony free laminating resin. It can also be applied using established resin spray equipment. It combines minimal burning characteristics with exceptionally low smoke and toxic gas generation.

Whilst the use of a gelcoat will reduce the fire resistance of Crystic 344A laminates, a smooth, resin rich surface can be obtained by the use of a surfacing tissue, and this will not detract from its fire performance characteristics.
