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.
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 ...
Lacquer is typically sprayed on, within a spray booth that evacuates overspray and minimizes the risk of combustion. The rule of thumb is that a clear wood finish formulated to be sprayed is a lacquer, but if it is formulated to be brushed on then it is a varnish. Thus, by far most pieces of wooden furniture are lacquered. [citation needed]
This is of particular interest in the area of polyurethane coatings, where light stability is a critical factor and is the main reason that aliphatic isocyanates are used in making polyurethane coatings. When PU foam, which is made using aromatic isocyanates, is exposed to visible light, it discolors, turning from off-white to yellow to reddish ...
Conformal coating spray booth. Spray coating can be completed with a spray aerosol or spray gun and is suitable for low- and medium-volume processing. The coating application may be limited due to 3D effects. The masking requirements have less penetration. This method can be used in spray booths for medium-scale production. [5]

Example of powder coating spray guns. The most common way of applying the powder coating to metal objects is to spray the powder using an electrostatic gun, or corona gun. The gun imparts a negative charge to the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the ...
Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...
