Jaguar XK150 in primer

Epoxy primer is used to seal a non-porous finish. It is recommended as the first base coat over any bare steel like on our 1961 Jaguar XK150. These base coats or epoxy primers can be used over fiberglass, plastic or the black iron phosphate coating.

This primer can also be used on cracks and dents. Its bonding capacity is excellent and produces a good surface finish. Epoxy primers not only offer excellent adhesion to metals, but also serve as a proper base for extra undercoat products, top coats and paint.

A two-part epoxy primer contains zinc phosphate, which acts as corrosion-inhibiting pigment. Epoxy primers can be used to waterproof materials that consequently protect the bare metal from oxidation. A dry, very clean surface is needed before applying epoxy primer. Two-part epoxy primer needs to be mixed thoroughly before applying.

Since paints in the automobile and marine industries are very important for resisting corrosion (rusting), epoxy coatings are widely used as primers to improve the adhesion of the metal surface. Epoxy primers are also used in structural steel coatings for high-build thickness with the application of only one or two coats.

A two-part epoxy primer is known as structural steel primer. It needs two components that are cured chemically through cross-linking. This two-part epoxy primer produces a film that is resistant to abrasion, chemicals and moisture. It is very suitable for use on properly prepared steel and concrete. This primer is also recommended for power plants, marine applications, water treatment plants and tank exteriors.

Further advantages of this primer include:

  • Water resistance
  • Corrosion inhibiting
  • Excellent adhesion

Primers are the most common undercoats used when refinishing car body shells.

They are great for building up and levelling areas or surfaces.

They provide a smooth surface for paint and they are great for adhesion as they provide a strong bond between the sheet metal or old paint and the new paint. Primers are rust resistance so they resist the formation of rust where they adhere to the sheet metal. They are able to fill sanding and grinding marks in old paint, sheet metal and fillers and can be sanded smooth or levelled quickly and easily. They act as a protective barrier to prevent the paint from soaking in and a good high-build primer should be ready to sand in as little as 30 minutes.
