Fraunhofer Umsicht
Patrick Masset, Fraunhofer Umsicht, Germany, presented testing of innovative PIN FR solutions as intumescent coatings to protect steel, wood or other materials from heat in case of fire. Homogenous, deep char layers were generated (no holes or cracks), with a low oxygen/carbon ratio and a residual mass of 40% of the coating initial mass. This enabled temperature behind c. 2mm steel to be kept around 100°C after up to 60 minutes for tests conducted 800°C.
These PIN intumescent coatings will be commercialised in coming months.
