Reaction to Fire

Reaction to Fire

Our powder coatings meet strict fire safety regulations

Recent development in the specification of construction materials means that providing comprehensive and up to date information is difficult. The information on this page is for guidance only and must not be regarded as definitive. We have highlighted only the specifications relevant to architectural powder coating which should not be applied to other paint finishes. To support you we provide a list of relevant organisations.

Powder coatings are a dry powder with no solvents and therefore no harmful volatile organic compounds. The fumes, on burning, from powder coatings have very low toxicity and a low rate and density of smoke generation. Thermoplastic (acid modified polyolefin) powder coatings also have high electrical and thermal resistance, suitable for cable conduits around underground rail tracks

Powdertech Wood Finish (PWF) achieves Reaction to fire classification A2-s1, d0. • Architectural powder coating materials meet current fire regulations •

Powdertech powders and products meet A2-s1, d0 specifications

Powder coating is not considered as detrimental to the fire resistance of metals.
