High Performance Flame Retardant Sealant Excellent Adhesion for Construction

Description

Flame Retardant Sealant, also commercially known as fire-stop or fire-rated sealant, is a specially formulated high-performance material designed to seal gaps, joints, and penetrations in structures and equipment. As a core product of passive fire protection systems, it plays a critical role in inhibiting the spread of flames, smoke, and toxic gases during a fire, effectively compartmentalizing fire-affected areas and extending evacuation time. Unlike ordinary sealants, it exhibits unique thermal response properties and meets stringent fire resistance standards, making it indispensable in industries where safety and fire protection are paramount.

Specification

Advantage

This flame retardant sealant meets stringent fire safety standards like UL 94 V-0 and GB 23864, effectively inhibiting flame spread and forming a protective carbon layer to curb fire expansion. It bonds strongly to metal, glass, concrete and plastic, sealing gaps tightly against smoke, toxic gas, moisture and dust for stable performance in harsh conditions. With wide temperature tolerance (-5°C to 230°C), it resists cracking or deformation in extreme heat or cold, suiting indoor and outdoor use. Low in VOCs and compliant with REACH and RoHS, it releases no harmful substances, ensuring environmental safety. It also boasts excellent UV, aging, corrosion and chemical resistance, maintaining long-lasting durability under sunlight, rain and industrial fumes.

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.
