Binders lacquers

Polymers are only marginally important in main memories of semiconductor technology, except for polymeric resist films used for chip production. For optical mass memories, however, they are important or even indispensable, being used as substrate material (in WORM, EOD) or for both substrate material and the memory layer (in CD-ROM). Peripheral uses of polymers in the manufacturing process of optical storage media are, eg, as binder for dye-in-polymer layers or as surfacing layers, protective overcoatings, uv-resist films, photopolymerization lacquers for repHcation, etc. 

EthylceUulose [9004-57-3], a cellulose either (qv), as prepared commercially, ie, of high DS, is thermoplastic and has alow density (1.14 g/cm ). It forms films of good thermostabiUty and excellent flexibiUty and toughness. EthylceUulose is used in lacquers, inks, and adhesives and is combined with waxes and resins in the preparation of hot-melt plastics. It is also used as a pharmaceutical tablet binder.

In the manufacture of coating materials, paints, varnishes, lacquers, dyestuff pigments, binding materials, and binders, surfactants are of great importance. Most of the systems used in these fields are dispersed. Therefore surfactants can accelerate the preparations of dispersions and improve their stability. For rewetting processes, like the so-called flush process, besides other anionic surfactants sulfosuccinates are also used. 

Modern lacquers with a low organic solvent content are widely formulated as stable lattices. Such a modified latex is useful as a coating for substrates such as paper, wood, and metals, and as a binder in aqueous systems. 

Used industrially in the manufacture of pharmaceuticals, textile chemicals, adhesives, binders, petroleum refining chemicals, fuels, lubricants, coating resins, varnishes, polymerizations, lacquers, agricultural chemicals, cosmetics, ion exchange resins, photographic chemicals, surfactants used in the paper industry and as a flocculation aid. 

A safety match requires for its ignition a rubbing on a "striking strip" which is covered with mixture such as consisting of red phosphorus 53, Sb sulfide 42 charcoal 5% in a binder such as NC lacquer, animal glue, dextrin, casein, plus hardener. Sb sulfide and charcoal serve as extenders to the phosphorus.

Oxidized carbon blacks may contain up to 15 wt% oxygen. They are strongly hydrophilic. Some of them form colloidal solutions spontaneously in water. In polar printing ink systems, lacquers, and coatings, a better wettability and dispersibility is achieved through surface oxidation [4.26], thus reducing binder consumption.

Nail polish consists of flexible lacquers, pigments such as organic dyes, iron or chromium oxides, and ultramarine blue along with drying agents and binders or vehicles such as ethyl acetate that evaporate on drying. Nail polish remover is usually an organic solvent such as acetone or ethyl acetate. 

The earliest binders were those which were already well known, either in adhesives or paints. They included corn syrup, glycerol, ethylene glycol and dextrose (all dispersed in water), asphalt-based varnish (in naphtha), and silicone varnish (in xylene). The range of binders which has been studied has since been extended enormously, to include lacquers, polymers, soluble salts, fused salts, fusible oxides and fluorides, ceramics and metals, and a number are listed in Table 11,1. 

The binders generally contains organic solvents which is not good for health, and are not always recommended. Paints, lacquers, varnishes or binders must be used so that they do not damage the function of firework pieces.
