CharCoat 1709 is a high-performance, 100% solids, two-component epoxy intumescent coating, tested to UL1709 and designed to provide passive fire protection for structural steel in extreme hydrocarbon fire conditions. It is engineered for both interior and exterior applications, delivering up to 300 minutes (5 hours) of protection while also offering corrosion resistance and chemical durability.
This advanced system uses epoxy intumescent technology that activates at high temperatures to form a protective char barrier, maintaining the structural integrity of critical infrastructure.

Constantly under test
Exterior weather testing
Catalogue projects for further analysis
When exposed to hydrocarbon fire conditions, CharCoat 1709 reacts to heat at approx. 175°C by swelling to many times its original thickness, forming a carbonaceous char. This insulating layer significantly slows heat transfer, keeping steel substrates below critical failure temperatures.
