Thermoguard Thermocoat S is a solvent-based intumescent paint system designed to protect structural steel and cast iron in exterior or exposed environments. It provides up to 90 minutes of fire resistance, forming a heat-activated insulating char that slows steel temperature rise in a fire.
Suitable for hollow sections and bracing, Thermocoat S is ideal for projects where durability and certified fire protection are essential. Use with a compatible decorative topcoat in BS 4800 or RAL colours to match your building’s design.
Fire tested to BS 476 Part 21 and backed by UKAS/EGOLF certification, Thermocoat S is approved for insurance, building control and client records.
