Cast Epoxy vs Thin Film Intumescent

With well over 20 years experience in the intumescent fire protection industry we've had the opportunity to see the long term results of using cast epoxy intumescent in contrast to thin film intumescent from a practical and aesthetic frame of reference. Below we present anecdotal evidence for our findings.

Now let's look at thin film intumescent paint.

Thin film intumescent applied to columns
can develop problems over time

They receive superficial repairs
but to what specification?

Even after expensive repairs
water ingress reappears
After expensive repairs were carried out by the paint manufacturer, the problem of water ingress reappeared, and so we understand that a complete secondary cladding system has recently been installed, at great expense, to conceal and protect the fire protection coating.

Problems at the base of columns
due to poor maintenance, corrosion and flaking often occur

can mean major disruption to the public
Conclusion
Whilst cast epoxy is initially more expensive and takes longer to install, in the long run, time and money are saved for the client, and the results are far superior to thin film paint. And let's not forget the fire protection period provided is longer with cast epoxy.

Designers May Fear New Fire Test

Designers may fear using suspension rods as part of the feature of their project because of the new testing regulations. You could speculate that there will be no interest from raw materials manufacturers of intumescent epoxy to fire test to this new standard. You could speculate that the testing bar has been raised unreasonably so to deter interest. Interact, with their partners Akzo Nobel were the only companies to test specifically some years ago. Interact has since tested again in anticipation of the impending BS EN 13381-10 and is currently negotiating to retest now that BS EN 13381-10 entered into law on 20 June 2020.
