A clear lacquer based on polymethacrylic ester leaves a film that does not yellow or craze on ageing as do many cellulose lacquers. Surface Preparation - Surface must be clean and free from all traces of wax, grease and metal polish. a b c d Webb, Marianne (2000). Lacquer: Technology and conservation. Oxford: Butterworth-Heinemann. p.3. ISBN 978-0-7506-4412-9. There are a number of forms of urushiol. They vary by the length of the R chain, which depends on the species of plant producing the urushiol. Urushiol can also vary in the degree of saturation in the carbon chain. Urushiol can be drawn as follows:

Lacquers are usually solvent based, which means brushes and spraying equipment need cleaning with white spirit / thinners. A maki-e and mother-of-pearl inlay cabinet that was exported from Japan to Europe in the 16th century. Unfortunately, We Cannot Guarantee Next Working Day - you will be notified if we can't fulfill this.The lacquer can be applied by spray and due to its low viscosity it is not normally necessary to thin.

Materials to be lacquered, must have a clean surface, with all dirt / grease removed. Lacquer should be applied in a dust free environment, with workers wearing appropriate protective clothing and breathing mask. Usually, the spray can version of lacquer is the easiest to apply, as the product can be sprayed lightly, allowing plenty of time between coats. If however, brush marks are left on the article when dry place the article on a hot radiator or in the oven at a low temperature, the brush marks will then disappear.

(1996), The Standard Catalog of American Cars 1805–1942, Kraus Publications, ISBN 0-87341-428-4 p.1050 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. [1]The problem with using nitrocellulose in lacquers was its high viscosity, which necessitated dilution of the product with large amounts of thinner for application, leaving only a very thin film of finish not durable enough for outdoor use. This problem was overcome by decreasing the viscosity of the polymer (the term actually post-dates the empirical solution, with Staudinger's modern structural theory explaining polymer solution viscosity by length of molecular chains not yet experimentally proven in 1920s) with heat treatments, either with 2% of mineral acid or in an autoclave at considerable pressure. [25] The trees must be at least ten years old before cutting to bleed the resin. It sets by a process called "aqua-polymerization", absorbing oxygen to set; placing in a humid environment allows it to absorb more oxygen from the evaporation of the water.
