Polya FR345 Unsaturated Polyester Resin
Polya FR345 Unsaturated Polyester Resin is a halogen-free, unsaturated polyester-based brushable resin. It has thixotropic (thickening) and flame retardant properties and is pre-accelerated.
This gelcoat is safely used in many applications requiring high flame retardant properties. Some of its common applications include the production of urban furniture, modular cabins, prefabricated houses, automotive and train parts, as well as the production of interior parts in the shipbuilding industries, where high resistance to Flame retardant.
Unsaturated polyester resin PULYA FR345 allows the production of composite parts that meet the requirements of the EN 45545 standard (HL-1 R1 and HL-2 R10 for specific requirements). It should be noted that according to this standard, manufacturers of composite parts must perform the relevant tests on the final part to ensure compliance with the requirements.
