An intumescent system is a combination of various compounds that in the event of fire react together as a result of the temperature increase to form a carbon foam. This foam attains a thickness of 10 to 100 times of the originally applied coating and insulates the substrate material through its low thermal conductivity. Clariant has an outstanding range of experience in raw materials for intumescent coatings and in the development of intumescent coating formulations, either water or solvent based.
Intumescent coatings based on our Exolit AP-range provide effective protection for objects such as steel-framed structures in modern buildings, which can lose their structural stability during fires, when temperatures exceed 500 °C, e.g. in airports, hospitals and offices. The Exolit AP products used are fine, white ammonium polyphosphate powders that develop their flame-retardant effect in the condensed phase.
Service for our customers
Clariant has been a leading supplier of phosphorus based flame retardants for more than 30 years. We are very pleased to support our customers to develop suitable intumescent coating formulations. In our laboratory at Knapsack, Germany, we can compare the performance of a range of different formulations using standard fire tests as a basis for evaluating new formulations for meeting new standards and challenges in fire safety requirements.
