A CONVERTER is a clear coating used as a base for the formulation and preparation of an enamel, be it high gloss or matt. It can be waterborne or solventborne, mono or bicomponent. Depending on the technical and aesthetic characteristics and weather resistances required, it is possible to choose between converters of various nature. They can be acrylic or polyurethane, polyacrylic or polyester, fast drying or synthetic, epoxy, nitro or chlorinated rubber and each one must be added with colored pastes in mixture in an adequate concentration to achieve the desired final color, optimal chromatic coverage and mechanical and outdoor resistances required. They are available in pre-weighed packs, i.e. with a predefined quantity of product inside them according to the percentage of pigmented pastes to be added.
