南京粉末新材料有限公司

Steel epoxy polyester powder coating contains epoxy and polyester resin. It is developed to provide more heat stability and chemical strength than epoxy powder coating. It has better resistance to acids, alkalis and solvents at room temperature. It is mainly applied where a tough decorative finish is needed such as camping equipment, cookers, domestic appliances, electrical cabinets, garden tools, light fittings, office furniture, partitioning, radiators etc. We can offer gloss and semi-gloss coating types to our customers. Preferred thickness is 60 microns for best results.

These are general purpose coatings where a limited amount of exposure to sunlight is experienced. They have all round generally good properties. Steel epoxy polyester powder coating is based on a combination of polyester and epoxy resins. This chemistry of powder coating finds its target market in a wide range of applications and hybrids perform well in non-weather able applications.
