PurColour Color Powder is nonflammable as a dust layer. PurColour Color Powder contains natural food grade fire retardant material and natural non-flammable inert food grade material in a proprietary blend that dramatically reduces the risk of an explosion in a dust cloud at certain concentrations. The product has been manufactured to meet Standard VDI 2263 Dust Fires and Dust Explosions Hazards — Assessment — Protective Measures Test Methods for the Determination of the Safety Characteristic of Dusts meaning the powder has been manufactured and tested to be non-explosive under certain test conditions and concentrations required by the standard, containing ingredients for explosion prevention and protection. “No” (no dust explosibility) is a very far reaching statement which can only be made if either no exothermic reaction is possible owing to the chemistry of the substance or if exhaustive tests on fine dust in a closed apparatus have not shown any characteristic pressure build up.

PurColour has produced demonstrations of flammability testing using the most extreme real life usage situations. The most extreme conditions with the use of PurColour color powder, is a high temperature, high concentration, and a high velocity color powder distribution. This is an atypical and non-expected usage with professional execution and informed usage. The demonstration is an example of extreme conditions.
