Advanced Powder Coating Technology

A novel powder coating manufacturing process has been developed based on the advanced supercritical fluid technology for material processing. The new process developed has several advantages over the conventional technology, viz.:

  • no need for extrusion
  • no need for or alleviation of dusty and energy-intensive size classification
  • better compatibilization between resin and ingredients
  • single train
  • lower temperature blending, thus ensuring no precuring of materials
  • better pigment dispersion, thus ensuring excellent color match, resulting in cost saving
  • better control of molecular weight distribution of resins (ideal for powder coatings) by a proprietary polymer synthesis process
  • excellent color match capability
  • small batch capability
  • environmentally friendly
  • applicable to a variety of polymeric resins as base resins including acrylics, polyester, epoxy, etc.

Key U.S. patents were issued and others are pending.
