Building and Construction
Fire safety is an essential element in building and constructions. National and international fire standards regulate the reaction to fire (ignition time, flame spread, smoke density, toxicity of gases) of materials used in this industry. In order to meet these fire safety requirements the use of flame retardants is often necessary especially in polymeric types of materials, e.g. in insulation, pipes and cables. The selection of the appropriate products depends mainly on the material and the required fire standard. Intumescent coatings based on PIN flame retardants ensure the stability of steel structures in case of a fire for a defined period of time (fire resistance), because steel can lose its strength at temperatures above 500 °C.
