DEFINITION

Classification: 427/189

(under subclass 180) Processes which include treating the particulate coating to make it continuous with no discernible particles.

(1) Note. Flame spraying is excluded from this subclass since it is assumed any particles being flame sprayed are not solid by the time they reach the base. Spraying molten particles is also excluded.

SEE OR SEARCH THIS CLASS, SUBCLASS:

252+, for pack processes wherein a base is adjacent particles which particles are heated to form gas which coats the base.

422, for spraying molten particles onto a base.

446+, for flame spraying.
