Description
Firecryl FR is a high-performance, fire-resistant acrylic sealant designed to block the spread of flames and smoke through joints and gaps. Upon exposure to heat above 120°C, it expands (intumesces) to form a heat-resistant barrier, making it ideal for enhancing fire safety in interior applications. Easy to apply and paintable once cured, it offers reliable adhesion to most porous construction surfaces and forms a waterproof, flexible seal.
