It is perfect for preventing tarnishing on metals which are particularly susceptible to oxidisation during wear such as brass and copper as well as for protecting patinas which you have purposefully applied, such as liver of sulphur. Lacquer-yielding trees in Thailand, Vietnam, Burma and Taiwan, called Thitsi, are slightly different; they do not contain urushiol, but similar substances called laccol or thitsiol. The result is similar but softer than the Chinese or Japanese lacquer. Burmese lacquer sets slower, and is painted by craftsmen's hands without using brushes. 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. 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 of various organic solvents. [2] Although synthetic lacquer is more durable than shellac, traditional shellac finishes are nevertheless often preferred for their aesthetic characteristics, as with French polish, as well as their "all-natural" and generally food-safe ingredients.

a b Franco Brunello (1973), The art of dyeing in the history of mankind, AATCC, 1973, ... The word lacquer derives, in fact, from the Sanskrit 'Laksha' and has the same meaning as the Hindi word 'Lakh' which signifies one-hundred thousand ... enormous number of those parasitical insects which infest the plants Acacia catecu, Ficus and Butea frondosa ... great quantity of reddish colored resinous substance ... used in ancient times in India and other parts of Asia ... From the 16th century to the 17th century, lacquer was introduced to Europe on a large scale for the first time through trade with Japanese. Until the 19th century, lacquerware was one of Japan's major exports, and European royalty, aristocrats and religious people represented by Marie-Antoinette, Maria Theresa and The Society of Jesus collected Japanese lacquerware luxuriously decorated with maki-e. [20] [21] The terms related to lacquer such as " Japanning", " Urushiol" and " maque" which means lacquer in Mexican Spanish, are derived from Japanese. [22] [23] Lacquer sheen is a measurement of the shine for a given lacquer. [8] Different manufacturers have their own names and standards for their sheen. [8] The most common names from least shiny to most shiny are: flat, matte, egg shell, satin, semi-gloss, and gloss (high).

Types of lacquer vary from place to place but they can be divided into unprocessed and processed categories. Asian lacquerware, which may be called "true lacquer", are objects coated with the treated, dyed and dried sap of Toxicodendron vernicifluum or related trees, applied in several coats to a base that is usually wood. This dries to a very hard and smooth surface layer which is durable, waterproof, and attractive in feel and look. Asian lacquer is sometimes painted with pictures, inlaid with shell and other materials, or carved, as well as dusted with gold and given other further decorative treatments. The first practical nitrocellulose enamel Glossy White S.2567, still for interior use, was introduced in 1919 in the UK by Nobel Explosives. [26] In 1923, General Motors' Oakland brand automobile was the first to introduce one of the new fast-drying nitrocellulose lacquers, a bright blue, produced by DuPont under their Duco tradename. [24] :295–301 In 1924 the other GM makes followed suit, and by 1925 nitrocellulose lacquers were thoroughly disrupting the traditional paint business for automobiles, appliances, furniture, musical instruments, caskets, and other products. [24] :295–301 Henry Ford and, in the UK, Herbert Austin were introducing nitrocellulose lacquers at the same time, and soon the market flourished. Coats: 1 coat is normally sufficient. If used on exterior objects, two or three coats is recommended. Drying Time: 2- 3 hours depending on temperature and humidity. Re-coating Time: 2- 3 hours depending on temperature and humidity.

Shellac, a natural resin secreted by the scaly lac insect, has been used in India for centuries as a decorative coating for surfaces.

Main article: Urushiol A Chinese six-pointed tray, red lacquer over wood, from the Song dynasty (960–1279), 12th–13th century, Metropolitan Museum of Art. The basic unprocessed lacquer is called raw lacquer (生漆: ki-urushi in Japanese, shengqi in Chinese). This is directly from the tree itself with some impurities filtered out. Raw lacquer has a water content of around 25% and appears in a light brown colour. This comes in a standard grade made from Chinese lacquer, which is generally used for ground layers by mixing with a powder, and a high quality grade made from Japanese lacquer called kijomi-urushi (生正味漆) which is used for the last finishing layers.The lacquer can be applied by spray and due to its low viscosity it is not normally necessary to thin.

Lacquers using acrylic resin, a synthetic polymer, were developed in the 1950s. Acrylic resin is colourless, transparent thermoplastic, obtained by the polymerization of derivatives of acrylic acid. Acrylic is also used in enamel paints, which have the advantage of not needing to be buffed to obtain a shine. Enamels, however, are slow drying. The advantage of acrylic lacquer is its exceptionally fast drying time. The use of lacquers in automobile finishes was discontinued when tougher, more durable, weather- and chemical-resistant two-component polyurethane coatings were developed. The system usually consists of a primer, colour coat and clear topcoat, commonly known as clear coat finishes. Compatibility: To prevent incompatibility please remove any old coatings with Rustins Strypit Paint and Varnish Stripper. Painting with metal lacquer is not difficult. Start by preparing the metal surface. For metal, it is crucial whether you want to paint untreated metal or metal that has already been painted. In any case, the surface must be clean and free of grease to ensure good adhesion. Roughen the surface with sandpaper. For large metal surfaces, you can use a sander. Tape off all surfaces that are not to be painted and also protect the surrounding area with a suitable cover.

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.

Metal Lacquer Applications

Midas finish seal lacquer is a water-based acrylic lacquer which forms a clear, hard, abrasion-resistant, protective finish to your jewellery and metal pieces. If the surface is not smooth, a nail brush should be used to ensure there is no polish left in the crevices.
