French polish is a process, not a material. The main material is shellac, although there are several other shellac-based finishes, not all of which classify as French polishing. The French polish technique is an effective method to accent exotic wood grain. The finish is softer than modern varnishes and lacquers, and is particularly sensitive ...
A finish made of shellac is UV-resistant. For water-resistance and durability, it does not keep up with synthetic finishing products. [40] Because it is compatible with most other finishes, shellac is also used as a barrier or primer coat on wood to prevent the bleeding of resin or pigments into the final finish, or to prevent wood stain from ...
Often, a final coat of wax is applied over the finish to add a degree of protection. French polishing is a finishing method of applying many thin coats of shellac using a rubbing pad, yielding a very fine glossy finish. Ammonia fuming is a traditional process for darkening and enriching the color of white oak.
The source of shellac resin is a brittle or flaky secretion of the female lac insect, Kerria lacca, found in the forests of Assam and Thailand and harvested from the bark of the trees where she deposits it to provide a sticky hold on the trunk. Shellac is the basis of French polish, which for centuries has been the preferred finish for fine ...
In terms of modern finishing products, finishes based on shellac dissolved in alcohol are often called shellac or lac to distinguish them from synthetic lacquer, often called simply lacquer, which consists of synthetic polymers (such as nitrocellulose, cellulose acetate butyrate ("CAB"), or acrylic resin) dissolved in lacquer thinner, a mixture ...
Japanning is most often a heavy black lacquer, almost like enamel paint. Black is common, and japanning is often synonymous with black japanning. The European technique uses varnishes that have a resin base, similar to shellac, applied in heat-dried layers which are then polished, to give a smooth glossy finish. It can also come in reds, greens ...
Heat-sensitive carbon fiber tubes coated with a UV curable powder coating. Powder coating is a type of coating that is applied as a free-flowing, dry powder.Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). [1]
