DSM Powder Coating Resins

The high energy prices have a large impact on the overall production costs for applying powder coatings to metal substrates which creates an increased demand for more economic powder coating systems.  In addition, the throughput time is an important item to decreasing the production cycle time which leads to better utilization of the production facilities.  This increases the production efficiency and subsequently decreases the overall cost of producing the powder coating.  Not only are costs of importance in the drive for reducing the energy consumption there is also a strong public demand to reduce the energy consumption in general.  A saturated polyester resin has been developed to answer the market demand for a low temperature cure resin suitable for cure with B-hydroxy-alkylamide crosslinkers.  The resin developed by DSM Powder Coating Resins allows for curing at temperatures lower than 160C with standard curing times while maintaining full impact resistance.  The resin also allows for a high degassing limit, excellent smoothness and is non-blooming.
