Recent developments in flame retardant polymeric coatings

This paper reviews the recent developments (last decade) in flame retardant polymeric coatings that mostly work by formation of conventional char (condensed phase) and or radical species in gas phase. Advancements in the method of application of such coatings on various substrates, problems of existing flame retardant coatings and new technological developments in terms of flame retardant chemistry are briefly discussed. This review focuses on various approaches in development of flame retardant coatings on various substrates i.e. incorporation of reactive and non-reactive organic compounds and organic/inorganic compounds (hybrid systems) based on metal, Si, P, N and halogens in suitable polymeric matrices and evaluation of their flame retardant characteristics using various analytical techniques.
