| Abstract | Abstract- The objective of the study is to develop a Poly sulphide –Epoxy resin based halogen free novel flame retardant coating which forms an insulating layer in the event of fire and its flame retardancy properties on wood based panel products and bamboo composites.The coating formulation was optimized by poly sulphide based epoxy resin as binder, ceramic material, carbohydrate and halogen free fire retardant which forms an insulating layer on the surface and blowing agent. In order to evaluate the flame retardancy properties the optimized coating was coated on the surface of plywood and bamboo composites and flame retardancy properties was carried as per both IS/BS Specifications. The data revels that the excellent flame retardancy properties like flame penetration, flammability was achieved, however the rate of burning was satisfactorily when tested as per IS: 5509. A Flame of LPG was allowed to play on the surface of coated and uncoated specimen to test Ignitability.and surface spread of flame.Result shows excellent flame retardancy properties compare to conventional flame retardant coating used.From physical observation it was observed that Thick coatings insulate the treated material against high temperatures. the coating melts under the action of heat, covering the treated material with an impermeable insulating crust that deprives the wood of oxygen. However the study reveals the generation of some gases on event of fire though there was no halogen and ammonium gases and coating was intumscent in nature.
