Abstract:
Free flowing resin powder which upon striking a heated article fuses, flows and hardens to provide a protective coating, which powder consists of a mixture of rough and rounded particles, the rough particles having a granular appearance as a result of being pulverized and the rounded particles having smooth, glossy, spheroidized surfaces as a result of being briefly heated to a temperature above the softening point. Preferably each particle of the powder is a blend of thermosetting resin and curing agent.
