Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity.
A coating is a covering that is applied to the surface of an object, or substrate. [1] The purpose of applying the coating may be decorative, functional, or both. [2] Coatings may be applied as liquids, gases or solids e.g. powder coatings.
Architectural coatings [1] [2] or paints [3] are paints and other coatings used to paint the exteriors and interiors of buildings, often called or external masonry coatings. Clear varnishes and lacquers are generally excluded. [1] Such products are usually designated for specific purposes such as roof coatings, wall paints, or deck finishes. [2]
Lacquer thinner — a combination of alcohols, alkyl esters, ethers, ketones, and aromatic hydrocarbons / arenes; Less common solvents used as paint thinner — like aromatic organic compounds that are more hazardous, so more heavily regulated and restricted in use — but still used in the construction industry include: [4] Aromatic ...
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]
Safe when solvent evaporates, used as food and pill coating Clogs spray equipment. Quick solvent flash time makes brushing difficult. Ox or badger/skunk hair brush recommended. Easy to pad, however French Polish is difficult Completely reversible using alcohol Excellent Nitrocellulose lacquer: Transparent, satin and gloss Reasonable protection
It is distinct from true East Asian lacquer, which is made by coating objects with a preparation based on the dried sap of the Toxicodendron vernicifluum tree, which was not available in Europe. Japanning is most often a heavy black lacquer, almost like enamel paint. Black is common, and japanning is often synonymous with black japanning.
Aircraft dope is a plasticised lacquer that is applied to fabric-covered aircraft. It tightens and stiffens fabric stretched over airframes, which renders them airtight and weatherproof, increasing their durability and lifespan. [1] [2] The technique has been commonly applied to both full-size and flying models of aircraft. [3] [4]
