THERMOSET® is a high-performance thermosetting coating for uncoated steel.
Heat Cured With A Harder Coating
Designed for a wide range of applications, Thermoset can be applied over galvanized steel and “black steel” (uncoated steel). Where a heat cured product is desired but a thin coat of a harder coating is needed to allow for architectural definition, Thermoset is the right material.
In Your Choice Of Colors
With Duncan Colorgalv Thermoset, the color range is virtually unlimited. Even small jobs can be given special colors. Download our pdf color chart to see our extensive color selection.
An Ideal Choice For Extreme Corrosion
Where extreme corrosion is a concern, Duncan Colorgalv Thermoset, utilizing the Duragalv® hot dip galvanizing system as a base, is the ideal choice. Where Duncan Thermoset is available for any metal substrate, Duncan Colorgalv Thermoset is designed to be applied over a freshly galvanized surface. Duncan Colorgalv Thermoset is available in a variety of formulations. Ask your Duncan Technical Services representative to recommend the appropriate system for your application.
