New developments in low bake matte powder coatings

摘要

The increasing demand for reducing carbon footprint(CFP)of coating systems is also related to the existing curing temperatures used for powder coatings.This sustainability improvement creates an increased demand for low temperature curing(LTC)powder coatings without adverse effect on the curing times which is equally important for lowering manufacturing costs.Additionally,LTC powder coatings can also be used at higher curing temperatures for a shorter time.Using LTC powder coatings also allows a wider range of parts to be coated.In the case of parts of a similar type,for example with very thin or very thick substrates,the lower peak temperature needed for powder coatings of this kind makes it possible for the coating to keep its nice appearance.Lower cure temperatures also open up new applications for the powder coating process.Metal substrates which,for functional reasons,cannot be exposed to high temperatures or complete assemblies which also have restrictions on their peak temperature can be coated using these LTC powder coatings.
