Abstract
Improved electrostatic coating is obtained by heat-rounding or spheroidizing pulverized resin particles so that 30-80% take on a glossy appearance while the rest remain rough to provide a mixture that is free flowing at ordinary room temperature and would pass through a screen having openings not exceeding 200 micrometers. Preferably each particle of the mixture is a blend of thermosetting resin and curing agent.
