The reaction to fire classification of Zenova FP on plywood as per BS EN 13501-1 is B – s2, d0.
This demonstration shows the protective charring effect of our Zenova FP Fire Protection Paint on timber. We applied 2 coats of Zenova FP to the timber, then lit and placed a torch just a few inches away, applying concentrated direct intense heat/flame to one spot and started the clock.
As you can see, a black protective char coating forms very quickly, protecting the substrate from heat and swelling further as time passes. This char absorbs the majority of the heat and flame and protects the substrate from being affected by the intense heat of the torch.
After 9 minutes the timber protected with Zenova FP is still very much intact and continues to be a solid piece of timber, unaffected by the intense direct flame.
Also known as thermofoaming paint or Intumescent Paint, ZENOVA FP is a fire-resistant water-based paint that prevents the ignition and spread of fire.
As a result of being exposed to heat, the intumescent paint swells and creates a light char foam, increasing in volume and decreasing in density. The heat transfer from the flames to the substrate is thereby greatly diminished. Treated materials become isolated from elements that maintain fire combustion since the paint turns into an insulating protective membrane.
