Paints industry

Colloid mills are used in the paint industry, and in the pharmaceutical and food-processing industries. 

The aromatic extracts have been used in the paint industry to partially replace linseed oil. They are still used for producing printer s ink. In addition, they are finding a variety of applications as plasticizers in the rubber industry or for the manufacture of plastics such as PVC. 

The properties of the polymers may be modified by mixing abphatic acids or anhydrides with the phthalic anhydride. Many alkyd resins find application in the paint industry. 

Chemical bleaching is never used on oils intended for edible use because it oxidizes unsaturated fatty acids to cause off-flavors. However, it does find wide usage for specialty linseed oil, for the paint industry, and fatty chemicals such as sorbitan esters of fatty acids and sodium stearoyl lactylate. Residual peroxide is destroyed by heating above its decomposition temperature.

Whereas the worldwide production of 2inc oxide [1314-13-2] is estimated to be around 500,000 t aimuaHy, only about 75,000—100,000 t are used for pigmentary appHcations by the paint industry. About 250,000 t are consumed by the mbber industry, and the rest is used in the production of plastics, paper, cosmetics, pharmaceutical products, ceramics, and glass (see Zinc compounds).

The white cast irons and their low alloys have good abrasion resistance properties [2,3]. White cast irons are used for grinding balls, segments for mill liners and slurry pumps. In the ceramic industry they are used for muller tyres and augers in the pulp and paper industry for attrition mill plates and chip feeders and in the paint industry for balls for grinding pigments. 

Synthetic resins form the heart of the paint industry. The tw o main types of synthetic resins are condensation polymers and addition polymers. Condensation polymers, formed by condensation of like or unlike molecules into a new, more complex compound, include polyesters, phenolics.. iniino resins, polyurethane, and epoxies. Addition polymers include polyvinyl acetate, polyvinyl chloride, and the acrylates,...

Safety No year goes by without some widely used chemical being declared suspect on toxicity grounds. The paint industry has responded rapidly to eliminate toxic chemicals from coatings or to show how they can be used safely in an industrial environment. Examples are the elimination of specific ether-alcohol solvents and the introduction of air-fed hoods for spraying isocyanates. Of particular interest in corrosion prevention is the current pressure to eliminate chromate pigments. Currently there are no equally effective alternatives and the emphasis has had to be on safe usage. The search for replacements continues. 

It is used largely in die plastics and paints industries and, when used at the 5% level in acrylic resins, it imparts the ability to hold printing inks. It is sold as the free add in two grades industrial grade or die purer, more expensive, refined grade. 

Although hardness is a somewhat nebulous term, it can be defined in terms of the tensile modulus of elasticity. From a more practical side, it is usually characterized by a combination of three measurable parameters (1) scratch resistance (2) abrasion or mar resistance and (3) indentation under load. To measure scratch resistance or hardness, an approach is where a specimen is moved laterally under a loaded diamond point. The hardness value is expressed as the load divided by the width of the scratch. In other tests, especially in the paint industry, the surface is scratched with lead pencils of different hardnesses. The hardness of the surface is defined by the pencil hardness that first causes a visible scratch. Other tests include a sand-blast spray evaluation. 

Alcohol ether sulfates with different number of moles of ethylene oxide are also used in emulsion polymerization and in the paint industry as dispersing agents. A particular use of alcohol ether sulfates is as foamers in low- and medium pressure drilling for water, oil, and gas. The foam produced by the surfactant reduces the pressure of the water column as water is replaced by air. 

Chain reactions are used to prepare a variety of high molar mass polymers of commericial importance and in practice may take one of four forms, namely bulk, solution, suspension, and emulsion methods. These four methods are described in the sections that follow, together with the loop modification which has become of commercial importance recently in producing latexes by emulsion polymerisation for the paint industry. 

Best Paint is a small Seattle company dedicated to producing safe paint products with a minimum of VOCs. Located in my neighborhood, this gem of a resource is owned and operated by co-founders John Pruitt and John Todd, two men who became chemically sensitive while working in the paint industry. Best Paint is advertised almost solely by word of mouth, and is carried only by a few retail outlets in Seattle special orders are shipped to environmentally ill consumers nationwide. The two owners are always busy making paint...

The effect of European REACH legislation, which will cover all chemicals used in the European countries, on the paint industry is discussed and proposals made for a possible solution. REACH is the abbreviation for Registration, Evaluation and Authorisation of Chemicals. A case study involving vehicle refinish paints is described. Recommendations made by the industry for an improved REACH are considered. 

The effect of environmental concerns on future developments in the paint industry is discussed. Particular attention is paid to volatile organic compound regulations, developments in powder coatings, and radiation-curable coatings. Tabulated information is presented on applications, backbone type and typical mechanical properties of Incorez W830 series PU dispersions and Incorez W2000 series uiethane/aciylic hybrids. 10 refs.

Organic pigments are used to color a variety of media. It is useful to distinguish between three primary fields of application the coatings and paints industry, the printing inks industry, and the plastics and fibers industry. Besides, organic pigments are used for special purposes, for instance in office materials and in the mass coloration of paper. 

Emulsion paints are based on aqueous synthetic resin dispersions, which afford a lacquer-like paint film. The resin dispersions which are commonly used by the paint industry contain water as the carrier phase. A large number of such dispersions are available, based on different resins such as poly(vinyl acetate), which may be employed as a copolymer with vinyl chloride, maleic dibutyl ester, ethylene, acrylic acid esters, polyacrylic resin, and copolymers of the latter with various monomers, as well as styrene-butadiene or poly(vinyl propionate). These disper-...
