Varnish industry

Because of their wide compatibility and solubility, coumarone resins are used considerably in the paint and varnish industry. The resins also find application as softeners for plastics and rubbers such as PVC, bitumens and natural rubber.

Gas chromatography is widely applied in the paint and varnish industry for analysis of solvents, oils, resins, plasticisers and polymers (by pyrolysis techniques). GC-TCD and GC-FTD on capillary and packed columns are used for direct determination of solvents in paints [143,144], DIN ISO 11890-2 describes an officially approved GC test procedure for solvents in paints and varnishes (VOCs 0.1-15%).

During acid sulfite pulping a-pinene and some monocyclic terpenes are partially converted to p-cymene (Fig. 7-18). Crude cymene can be separated from the digester gas relief condensates and purified by distillation. With spruce and fir the distilled product is 99% p-cymene and only minor quantities of other products, such as borneol and sesquiterpenes, are present. Pine wood contains 3-carene, which affords appreciable quantities of m-cymene besides p-cymene. The crude cymene can be used within the mill as a resin-cleaning solvent. The distilled p-cymene finds use in the paint and varnish industry. 

A most important development in the modem paint and varnish industry has been the introduction of synthetic resins as replacements for natural resins in the manufacture of varnishes and enamels. By using synthetic resins it has been possible to produce a variety of coatings that, in many cases, have important points of superiority over any of those compounded from natural resins. The synthetic vehicles are particularly distinguished by their hardness and durability and their high degree of resistance to the action of water, alkalies, and other chemical agents.

He makes sure that his chemicals, especially the nitroethane, are of a good grade. Nitroethane is widely used in the paint and varnish industry as a solvent for cellulose acetate lacquers, vinyl resins, nitrocellulose, waxes and dyes. If he has the industrial grade, he first distills it before use. Benzaldehyde smells like bitter oil of almonds and should be clear. Benzaldehyde is used in flavorings and perfumes. 

Advanced crack-resistant coatings based on water dispersion of chlorine-sulpho-polyethylene (CSPE, Hypalon ) vulcanized by a Mannich alkali (MA) water solution were obtained. Application of MA as a CSPE structure component makes it possible to produce a vulcanized net of saturated polymer, and thus to develop an ecologically safe, impenetrable crack-resistant coating for any substrata (concrete, metal, plastic, etc.). The coatings can be applied in the aircraft, automotive, shipbuilding, paint, and varnish industries, civil engineering, and so on as a corrosion-resistant material. The optimal coating composition and its mechanical properties have been studied. 

The production of turpentine by distillation of gum from pine trees was the start of the solvents industry in the United States early in the eighteenth century. By 1900 the annual production was 30,000,000 gal and averaged this amount through many years. Turpentine was the solvent of choice for the paint industry, and 80% of the volume in 1922 was used in the paint and varnish industry...

Surfactants are used in the so-called flush process in the dye and varnish industry. Organic and inorganic pigments are transferred from an aqueous medium into an oily medium in this procedure. In addition, surfactants disperse pigments in dyestuffs, emulsify pigments in emulsion dyestuffs and stabilize the formulations of dyes and varnishes.

Furthermore, drying oils can be combined with all kinds of other substances the results obtained with synthetic resins are of extreme importance for varnish industry. 

There are cases where Ter is higher than the boiling point of the solvent, for example in the case of cellulose and water. Then no complete dissolution can be obtained by heating, and chemical means must be introduced. Either the composition of the solvent must be adapted — a procedure much encountered in paint- and varnish-industry — or the constitution of the polymer has to be changed, a method followed in the rayon industry (cellulose cellulose xanthogenate). Such problems will be reconsidered in this book by P. H. Hermans.
