FX-100™ is a clear two-part, intumescent coating with a substantially lower activation temperature than other intumescent coatings. This early protection allows the use of FX-100™ on substrates that most intumescent coatings cannot protect, including wood, some plastics, and other combustible substrates with low ignition temperatures. Upon exposure to heat or flame, the FX-100™ coating intumesces, building a foam char up to 100 times the original applied coating thickness. This foam char provides a functional fire barrier, protecting the substrate against both heat and flame.
