The fireproof sealant is a water-based intumescent fireproof sealant free of halogens and asbestos, with a maximum fireproof duration of up to 3 hours. It has good airtightness, water tightness, smokeless toxicity, corrosion resistance and explosion-proof pressure-bearing capacity, and a long-term fireproof performance of 30 years.

● Fire resistance performance ≥ 3 hours

● Expands when exposed to fire, providing good fire protection

● Resistant to acid, alkali, corrosion, water, damp heat, and freeze-thaw cycles

● Free of halogens, asbestos, and volatile organic solvents

Suitable for fireproof and waterproof sealing of various penetrations. It is easy to construct, allows for subsequent addition of new cables and re-coating, and can be easily cleaned with water (before solidification). It is widely used in scenarios such as gaps at penetrations of steel or copper pipes with thermal insulation layers, cable bundles, plastic pipelines (≤50mm), and HVAC ductwork.
