Powder coating over galvanised items INGALSM3

Polyester powder (PE) coatings are thermosetting resins where a low molecular weight polymers and flows during fusion while simultaneously undergoing a chemical conversion to a thermoset or cross-linked condition. Once cured at temperature, the polymer cannot be re-melted to a plastic condition, as is the case with thermoplastic resins like PVC. The use of polyester powder coatings has been well established since the 1960’s, and the process is well suited to coating large volumes of uniform products.  Polyester powder coating of hot dip galvanized surfaces can be accomplished successfully with proper process and quality controls. There is an opportunity to extend the application of polyester powders to heavier steel sections and fabrications with the attendant cost and performance benefi ts of powder coatings.  Extract from INGAL Specifiers' Manual - 3rd Edition.  Full manual at www.ingal.com.au
