Fire retardant coatings under climatic stress
Fire retarding coatings provide the fire protection for flammable substrates. Under heat exposure a thick fire-resistance char barrier is formed in an intumescence process. This thermal insulation helps to prevent the substrate from ignition or deformation. The protection of materials against fire has become an important issue in the construction industry. Intumescence coatings play the key role for fire retardant strategies. Nevertheless, there is a demand for significant improvement of their properties and performance. At WKI new high performance fire retardant coatings with improved waterproofing performance suitable for outdoor application were developed. A waterborne coating was used as a model system. The individual components contained in the intumescent coatings were investigated in reference to the water resistance of the obtained coating. Significant changes in waterproofing performance were achieved by the modification of the composition of the intumescence mixture using commercial products. Additionally innovative encapsulated materials with low wettability were prepared. The designed particles were produced by combining commercially available micrometer- and nanometer particles during hybridization process. The results are compared and discussed.
