CharCoat SC is a high-performance, water-based thin-film intumescent fire protection coating designed for use on structural steel. Engineered to offer up to 120 minutes of fire resistance (BS 476 Part 21), it expands rapidly when exposed to heat, forming a robust insulating char that safeguards steel integrity during fire exposure.
This single-component solution combines aesthetic flexibility, low VOCs, and exceptionally low dry film thicknesses (DFT), making it an ideal choice for interior and semi-exterior applications in architectural, industrial, and commercial settings.

This single-component solution combines aesthetic flexibility, low VOCs, and exceptionally low dry film thicknesses (DFT), making it an ideal choice for interior and semi-exterior applications in architectural, industrial, and commercial settings.
CharCoat SC utilizes intumescent technology—upon exposure to fire, the coating undergoes a controlled chemical reaction, expanding 20 to 30 times its original thickness. This results in a durable char layer that insulates steel substrates against extreme temperatures, maintaining structural stability and preventing collapse.
