Title Minimum ignition energy of coating powders for electrostatic coating
Original title Die Mindestzündenergie von Pulverlacken für die elektrostatische Pulverbeschichtung [in German]
Bibliographic information 1993, Vol.103, No.4, p.329-333. Illus. 5 ref.
Abstract More than 40 coating powders were tested to determine their minimum ignition energies, which depend on the specific surface area of the powder calculated from the particle size distribution. In addition, the chemical composition of the powder, the amount of resin, and the tendency to agglomerate have an influence. The lowest ignition energy, 1.7mJ, was obtained for transparent epoxy coating powders with particle diameters below 25µm. There is no fire or explosion hazard with these powders if they are applied with hand-held spray guns according to EN 50050.
