Product characteristics

eCoils > Product > Product characteristics

Usually, we apply a two-coat painting system, even if it is possible to obtain products with a single coat.

The primer is applied directly on the pre-treated surface of the metal.

It generally contains anti-corrosive pigments to help protect the metallic substrate from corrosion.

The second coat of paint, which serves as the “finish”, provides the colour and appearance of the end product, offering significant protection against bad weather and the mechanical characteristics of the systems.

The overall thickness of the finished product is generally between 5 to 15 microns for the primer and 15-30 microns for the finishes.

The thickness is obviously determined by the final requirements of the pre-painted metal product.
