Our powder coatings meet strict fire safety regulations.
Architectural powder coating materials meet all current fire regulations, including Reaction to Fire Specification A2-s1, d0.
- Polyester 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.
- Polyester powder coating is not considered to be detrimental to the fire resistance of the underlying metal
- Where Reaction to Fire compliance is a project requirement, Powdertech use specific application techniques and an increased number of measurements of the cured powder film thickness which are recorded to provide evidence of compliance to the “Field of application” as detailed in the fire BS EN 13501-1 documentation for the range of powder coating products manufactured by the supplier.
- Powdertech finishes Satellite, Wood finish and Evolution have all been certified A2-S1, d0 in September 2023 in accordance with BS EN 13501-1. Summary documents are in the data sheet records.

Continuing development in the specification and installation 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 have provided a list of relevant organisations to contact for further advice - see above.
