摘要: 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 mixture free flowing at ordinary room temperature and would pass through screen having openings not exceeding 200 micrometers. Preferably each particle of blend thermosetting curing agent.
