One-component, low temperature curable coating powder |
摘要 |
A mixture of a self-curing epoxy resin having an equivalent weight of from about 100 to about 700, a melt viscosity of from about 200 to about 2000 centipoise at 150° C. and a low temperature curing agent capable of maintaining its own domain during extrusion which is extruded as one component at a temperature below 220° F. and the extrudate is cooled and pulverized to form a low temperature curable coating powder. The powder cures at a temperature of from about 225 to about 300° F. and produces a coating having an exceptionally smooth surface with either a low or high gloss. The powder is particularly useful for coating heat sensitive substrates such as plastics, paper, cardboard and wood.
