Formulated with specialized fire-retardant additives and acrylic emulsions, ASMACRYL-55 is engineered to deliver reliable fire protection in building joints subjected to moderate movement. It applies easily and cures to form a durable, partially flexible seal that expands when exposed to temperatures above +120°C, helping to block the passage of fire, smoke, and toxic gases. Capable of delivering up to 4 hours of fire resistance, it is ideal for sealing joints between construction elements in residential, commercial, and industrial buildings where fire safety is critical. Its gun-grade consistency ensures precise application, making it a practical and efficient solution for both new constructions and retrofitting fire-rated joints.
