PAINT COMPOSITION AND PAINT SPRAYING APPARATUS WITH PREHEATED PAINT

摘要

This invention describes the development of a novel spray paint High Volume Low Pressure (HVLP) apparatus including a membrane pump to allow for the handling of higher viscosity paint to facilitate high layer−thickness applications (typically in a single paint application) with a marked reduction in over−spray. The apparatus functions by using heated air and allows for heating of waterborne paints and in particular a novel waterborne paint also the subject of this application. This waterborne paint provides for better levelling, drawing and application of the paint product to a desired substrate. The paint product claimed in the invention has a product to a desired substrate. The paint product claimed in the invention has a viscosity profile tailored for use with the spraying apparatus of the present invention. A further aspect of the present invention comprises the combination of the painting apparatus and the sprayable paint product as an effective integrated painting system.
