The pits are generally embossed into the substrate (polycarbonate or polymethylmethacrylate) layer by an injection-molding process, and are used to indicate whether a data bit is 0 or 1. An aluminum or silver layer provides a reflective surface, and is protected from corrosion and damage by a radiation-cured acrylate (lacquer) layer, onto which a label is usually printed.197... 

The result was the compact disc (CD). Made from 1.2 mm of polycarbonate plastic, the disc is coated with a much thinner aluminum layer that is then protected with a film of lacquer. The lacquer layer (10) can be printed with a label. CDs are typically 120 mm in diameter, and can store about 74 minutes of music. There are also discs that can store 80, 90, 99, and 100 minutes of music, but they are not as compatible with various stereos and computers as the 74—minute size. 

Instant tack labels find special usage on seals, pleated overwraps, and various header labels. They are not used for bottle or can labeling. Blister and strip packs are classified as part of this category, as we require the temperature of the lacquer to be raised high enough to obtain a permanent bond with the inner surface of the base material. Pressure needs to be applied as well, and usually there will be a knurling implanted onto the mating surfaces. 

The simplest thermometers are bistate/phase change sensors. These low-cost nonelectric sensors can be crystalline solids that change from a solid to a liquid at a particular temperature or can be crayons, lacquers, pellets, or labels over a wide range of temperatures from 38 to 1,650°C (100-3,000°F). They offer a very inexpensive method for visual verification within about 1°F. 

Tamarind preparations shall be packed in tin plate or glass containers which should be sealed appropriately. The tin plate container shall be lacquered with acid-resistant lacquer. Each container should be labelled with the name of the material, name and address of the manufacturer, net mass of the contents of the container in grams, date of manufacture, list of additives and manufacturer s licence number. Requirements for tamarind concentrate and limits of heavy metals are given in Table 20.8. 

Store pesticide containers with the label in plain sight. Costly errors can result if the wrong pesticide is used by mistake. Labels should always be legible. They may be damaged or destroyed by exposure to moisture, dripping pesticide, diluents, or dirt. You can use transparent tape or a coating of lacquer or polyurethane to protect the label. If the label is destroyed or damaged, request a replacement from the pesticide dealer or the pesticide formulator immediately. 

DNA, RNA, or protein, which can then be probed with a labeled sequence or antibody (Western blot assays), microscopy embedding, electrotechniques, skin protectants, microfilters, and others. Nitrocellulose continues to be used in photography, the manufacture of lacquers, patent and natural leathers, artificial pearls, process engraving, and cements. 

Use Optical bleach in textile industry, in coatings for paper, labels, book covers, etc to lighten plastics, resins, varnishes, and lacquers invisible marking agent.

The reflective layer is a thin layer of aluminium, vacuum evaporated onto the disc under clean room conditions (not more than 100 particles of size greater than 0.5 xm in each cubic foot of air). A subsequent lacquer coating is UV cured, then overprinted with the label, further protecting the pits underneath.

The third edition of Tingry (1830) lists alkanet as a dye used to colour lacquers, while in 1860 Ure (giving the species as Anchusa tinctoria) states that it is grown in Montpellier, France and in the Levant. Salter (1869) describes it as the basis of what he calls violet carmine (. v.) and Schweppe (1992) identified a sample from the Deutsches Museum in Munich labelled Karmineviolett as aluminium lake of alkanna. 

Products based on PSAs are protective films, self-adhesive labels and tapes. Protective films are made from flexible plastic material (PP, PE, PVC) coated with PSAs (5-15 g dry m ) and they are used to protect painted or polished metal surfaces, lacquered furniture surfaces, acrylic sheets from scratching and soiling during manufacture, shipping...
