• no need for extrusion or melt processing for ingredient mixing
• no need for or alleviation of dusty and energy-intensive size classification
• better compatibilization between resin and ingredients
• single train possibility
• 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.
• producing higher quality coatings
