Fireguard 78PA is a pre-accelerated fire retardant gelcoat designed for applications requiring the highest levels of fire & smoke performance.
This is a halogen-free, intumescent flame retardant gelcoat based on an unsaturated polyester resin formulated for spray application. Due to its unique combination of special flame retarding additives, Fireguard 78PA gives outstanding fire protection properties to composites which are accidentally exposed to fire.
Fireguard 78PA protects the substrate through the intumescence effect and acts mainly in the solid phase. When subjected to heat, Fireguard 78PA forms a protective layer, preventing the access of oxygen to the substrate. This also prevents further polymer combustion and flame propagation.
