Why choose our Flame Retardant Sealant?

Why choose our Flame Retardant Sealant? Because safety shouldn’t be compromised, and performance shouldn’t be limited. Our sealant meets global fire safety standards like UL 94 V-0 and ASTM E 814, forming a dense, heat-insulating carbon layer when exposed to fire to block flames, toxic smoke, and superheated gases—buying precious time for evacuation and protection. It bonds seamlessly to metal, concrete, plastic, and masonry, even slightly wet surfaces, eliminating gaps that risk fire spread while withstanding ±25% joint movement without cracking. Designed for versatility, it thrives in extreme temperatures (-5°C to 230°C+) and resists UV, aging, and corrosion, performing reliably indoors and outdoors for years. Free of halogens, solvents, and harmful VOCs, it’s eco-friendly and safe for both people and the environment, complying with REACH, RoHS, and LEED standards. Easy to apply with standard tools and paintable to match any surface, it’s the all-in-one solution that combines uncompromising fire protection, durable sealing, and hassle-free use—because when it comes to safety, you deserve a sealant you can trust.
