RAL1007 daffodil yellow pure powder coating for garden furniture
Epoxy coatings are used wherever a hard, electrical insulating coating is required to provide protection over a wide temperature range.
Depending on the particular epoxy selected, these coatings can be used up to 150C or higher.
Epoxy powder coatings have dielectric strength of up to 1200 volts / mil., in thicknesses over 10 mils
They are, therefore, ideal as functional electrical insulators as well as a protective coating.
