Methods for improving the electrostatic charge of powder coatings or powders and their use for surface-coating solid articles

摘要

Process for increasing the electrostatic chargeability of powders, especially powder coatings for the surface coating of solid articles, by incorporating into the powder at least one triarylmethane, azine, thiazine and/or oxazine compound in an amount of from about 0.01 to about 10 per cent by weight until homogeneous, the said compounds being dissolved or dispersed in the powder coating system or powder.
