Intumescence

 

Intumescent coatings are designed to react and swell to many times their original thickness when exposed to heat. A carbonaceous char is produced which creates an insulating layer protecting the material or equipment the to which it is applied.

Intumescence

​

  • Simultaneously Solid coating converts into a highly viscous liquid

  • endothermic reactions are initiated that release moisture, and inert gases

  • Char radiates 80 - 90% of the heat back into the fire. WHAT IS CHAR?

  • Result: the protected E.S.D.S’s temperature is controlled so that functionality is maintained

  • The coating continues to react in a sacrificial manner until all of its components are used up
