thermoset powder coatings

The functional thermoset powder solution.


The functional thermoset powder solution.

The Protech Group’s EF-SERIES™ is the ideal coating solution for high corrosion and chemical resistant requirements. These powders can be used as a one-coat protective application or as the base coat in a three-coat system. EF-SERIES™ powders are formulated to provide a flexible yet extremely durable finish. These epoxy powders have also proven to provide superior adhesion properties and superior resistance to delamination and cathodic disbondment. EF-SERIES™ conforms to ASTM 775-86 and ASTM 775-89 and has been approved by the U.S. Federal Highway Administration for the protective coating of shotblasted reinforcing bars. EF-SERIES™ is also an ideal application for metal packaging used in the cosmetic, pharmaceutical, chemical and food industries. The powders are completely impermeable prevent-ing the metal packaging from coming into contact with the enclosed contents. EF-SERIES™ coatings are 360º powders which allows a consistent application to the entire inner area of the substrate. They are totally inert powders compliant with global regulatory agencies such as the FDA. EF-SERIES™ demonstrate excellent abrasion and chemical resistance.
