Epoxy Primers

Epoxy primer is used to coat steel, aluminum, and composite surfaces before painting. It has superior anti-corrosive properties that exceed one-part zinc chromate primers in all levels of performance. Epoxy primers may be used under enamels, Ranthane polyurethane, and a variety of other topcoat paints. Epoxy primers may be applied directly over old one-part primers like zinc chromate or red iron oxide to provide a solvent-proof barrier coat to protect from fabric cements and dopes.

Epoxy primer comes in two colours: white or dark green; both have identical properties and ingredients and vary only by colour.

Cured epoxy primers are completely solvent resistant and are not wrinkled or lifted by fabric cements or dopes.

White is the easiest colour to use under any colour paint and is always a better choice for aluminum, steel or composites that will be topcoat painted. Dark green is actually white primer tinted green for those who want to simulate the colour of WWII zinc chromate on war birds.

There are three parts to an epoxy primer kit: EP-420 Primer, EP-430 Catalyst, and E-500 Reducer; all are required and cannot be substituted.

 

The Gallon Kits consists of 1 Gallon of the EP-420 Primer, 2 Quarts of the P-430 Catalyst and 1 Gallon of the E-500 Reducer.

 

The Quart Kits consists of 1 Quart of the EP-420 Primer, 1 Pint of the P-430 Catalyst and 1 Quart of the E-500 Reducer.

 

This primer is supplied in a kit of 2½ US quarts (just over 2 litres) or 2½ US gallons (combined volume). Each kit contains paint, catalyst and thinners.
