Powder-coated glass products

摘要

A method of manufacturing a powder-coated glass product. The method comprises depositing thermosetting powder on the upper most first surface of the glass substrate and curing the thermosetting powder to form a coating on the first surface. The curing step comprises applying heat via infra-red radiation located below the second surface of the glass substrate and via the second surface of the glass substrate. The source of infra-red radiation comprises a box having an internally-reflective surface and a heat-transmissive lid located below the second surface of the glass substrate. At least one infra-red lamp is located within the box to emit the infra-red radiation into the box, and the infra-red radiation emitted into the box heats the air within the box for conduction of heat from the air through the lid to the second surface across the gap between the lid and the second surface of the glass substrate.
