Abstract
The present disclosure involves apparatuses and methods for coating a lapping plate with an aqueous composition. The apparatus can be configured and the aqueous composition can be formulated so that the aqueous composition can flow to a spray nozzle device solely due to gravity in a batchwise manner.
Claims20
A method of coating a lapping plate platen, wherein the method comprises:
- a) providing a first volume of an aqueous composition in a container, wherein the aqueous composition comprises:
- i) a solid resin powder;
- ii) a plurality of solid abrasive particles;
- and
- iii) an aqueous carrier;
- b) providing a spray nozzle device in fluid communication with the container;
- c) spraying a second volume of the aqueous composition onto an underlying lapping plate platen to form a layer of the aqueous composition on the surface of the platen, wherein the aqueous composition has a viscosity so that the aqueous composition can flow from the container to the spray nozzle device due to gravity.
