Flame Retardant Powder Coating

DESCRIPTION Flame retardant powder coating is often required to protect a wide range of products of both flammable and nonflammable against fire. It is an oldest, most efficient, and easiest method to apply any surface without modifying the intrinsic properties of materials. Moreover, the initial phase of fire always occurs on the surface by ignition, and hence, it is important to concentrate on the surface protection of a material. Being an organic nature of conventional surface coating will burn easily and generate smoke and toxic fumes, which may not be suitable for application where fire protection or fire prevention is required. Reaction-to-fire and/or resistance-to-fire are to be considered for assessing both flammable and non-flammable material by using fire retardant and fire resistant or fire protective coatings. The degree of fire retardation mainly depends on the coating thickness, substrates, and efficiency of formulations. This chapter explains briefly the fire retardation of wood by using flame retardant powder coating.
In general, conventional organic surface coating is easily ignitable, melts, drips, and it may cause severe injury and damage to the substrates in the event of fire. Therefore, flame retardant powder coating that is designed to formulate should not contribute a significant amount of fuel to the fire and, at the same time, limit the flame spread and smoke development. Fire retardant coating is one of the easiest, oldest, and most efficient ways to protect the materials against fire. This approach does not cause chemical modification of the substrate, but rather the formation of a protective layer which alters the heat flux to the substrate and can inhibit its thermal degradation, ignition, or combustion. The ideal fire retardant coatings should have minimum flame spread, negligible or low release of smoke and/or toxic gases, be easy to apply, show good wear resistance, adhere to the underlying substrate and offer low cost. Typically, they are based on chlorinated alkyds or brominated epoxy resin and filled aluminum hydroxide or a combination of chlorinated paraffin and antimony oxide system. However, the wide range of flame retardants in the form of reactive or additive and different classes (halogen, phosphorus, nitrogen, minerals, oxides, intumescent, and nanofillers) are available commercially that are incorporated into coating formulations to inhibit or retard the burning of materials. The selection of flame retardants can be tailor-made for a specific polymer binder in coating formulations. Fire retardant coatings look like architectural paints and mainly available in solvent form and are applied by conventional methods, brush, roller, and spray.
