Polyurethane raw materials for environmentally friendly powder coatings
For the formulation of environmentally friendly and high quality coatings systems meeting the VOC directives powder coating systems take their place alongside waterborne systems and high solid systems. As a solvent-free alternative for conventional metal coating systems polyurethane powder coatings are becoming increasingly popular for finishing decorative metal objects and for equipment OEM. They exhibit outstanding mechanical properties and have a number of additional advantages. Any overspray can almost entirely be recycled.
The advantages at a glance:
More than 90% utilization of the raw material depending on the recycling system - highly efficient
40-150µm layer thickness in one work cycle
Fully automated coating with modern equipment and technology
Quality control, finishing and immediate processing of the finished parts after the cooling process
Environmentally friendly technology, compatible with stringent legislation (VOC)
Very good chemical and physical resistance
