Bei niedriger Temperatur härtbare Einkomponenten-Pulverbeschichtungszusammensetzung

摘要

A mixture of a self-curing epoxy resin having an equivalent weight of from 100 to 700, a melt viscosity of from 200 to 2000 centipoise at 150 DEG C and a low temperature curing agent is extruded as one component at a temperature below 105 DEG C and the extrudate is cooled and pulverized to form a low temperature curable coating powder. The powder cures at a temperature of from 107 to 149 DEG C and produces a coating having an exceptionally smooth surface with either a low or high gloss.
