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. Lacquers are usually solvent based, which means brushes and spraying equipment need cleaning with white spirit / thinners. 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] Rustins Metal Lacquer is a clear UV resistant lacquer that leaves a film and does not yellow or craze on ageing. It has excellent adhesion on chrome, brass, copper and silver. It keeps the shine on Brass, Copper, Chrome, Silver, Aluminium & most polished metals. How to use Rustins Metal Lacquer. 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.

Compatibility: To prevent incompatibility please remove any old coatings with Rustins Strypit Paint and Varnish Stripper.Metal lacquers provide a protective finish against dirt, debris, and other contaminants. The metals that respond best to metal lacquer finishes include: Types of lacquer vary from place to place but they can be divided into unprocessed and processed categories. a b c Dutton, William S. (1942), Du Pont: One Hundred and Forty Years, Charles Scribner's Sons, LCCN 42011897. 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. In modern techniques, lacquer means a range of clear or pigmented coatings that dry by solvent evaporation to produce a hard, durable finish. The finish can be of any sheen level from ultra matte to high gloss, and it can be further polished as required. Lacquer finishes are usually harder and more brittle than oil-based or latex paints, and are typically used on hard and smooth surfaces. [ citation needed]

A clear lacquer based on polymethacrylic ester leaves a film that does not yellow or craze on ageing as do many cellulose lacquers. Lightly tarnished surfaces should be cleaned with a good quality metal polish, which must then be removed with warm soapy water. 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:Unfortunately, We Cannot Guarantee Next Working Day - you will be notified if we can't fulfill this. 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.

If possible objects such as letterboxes should be removed from the door so that at least one coat of lacquer can be applied to the edges of the reverse side. Many metals suffer from surface tarnishing and even corrosion, if left open to the atmosphere / air. Surfaces can be protected through the application of different finishes, such as paint or powder coating. However, sometimes the surface of metals can be attractive without the need for a coloured coating. This is when lacquer is most useful. Lacquer is usually applied as a clear coating, leaving the surface texture on view. Lacquer forms a protective clear layer on metals and is particularly useful on brass, aluminum, silver and copper, which are often in the form of decorative items. When lacquered, polishing and cleaning will no longer be required. 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. Kimes, Beverly R.; Clark, Henry A.

Has excellent adhesion on Chrome, Brass, Copper and Silver and provides a UV protection. The lacquer should be applied liberally with a flowing action using a soft brush. 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. Kathryn Santner (October 2, 2012). "Writ in Lacquer: A Genteel Courtship on a Mexican Sewing Box".

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.
