Everbuild Fire Mate Intumescent Acrylic Sealant White 295ml

Everbuild Fire Mate Intumescent Acrylic Sealant in White, supplied in a 295ml cartridge. This is a one-part, emulsion acrylic-based sealant designed to provide a fire-resistant and acoustic joint seal in a range of fire-rated structures. When exposed to temperatures above 125°C, the material expands to more than 150% of its original volume, forming an insulating char that prevents the passage of fire, smoke, and toxic gases. The formulation is permanently flexible, allowing movement of up to ±7.5% without loss of adhesion, and can be applied to joints up to 50mm wide. Fire Mate maintains its stability and finish in interior applications where both flame resistance and sound insulation are required, delivering a dependable seal with a curing time of 3 to 5 days at room temperature.
