An examination is made of a European Union directive aimed at limiting emissions of volatile organic compounds arising from the industrial use of organic solvents. Proposed emission limits applicable to the use of solvents in coatings, inks and adhesives manufacture, adhesive bonding and rubber processing are presented. 

An urethane-based pressure-sensitive adhesive composed of a liquid hydroxytelechelic polybutadiene and a polyisocyanate does not require a solvent in coatings onto label sheets. This polymer together with the (polystyrene-co-butadiene) copolymer and a polyisocyanate was applied in steel coatings 239 240>. 

It has been estimated by Doolittle and Holden (T) that, excluding petroleum hydrocarbons, the protective coatings industry in 1933 consumed about 40% of chemicals classified as solvents. By 1949 only 25% of these solvents were used in coatings ( 5), and by 1972 it was estimated by Stewart (6) that only 14% of oxygenated solvents (which include ketones, esters, alcohols, and glycol ethers) were consumed by the coatings industry. The total consumption of these solvents in coatings was estimated at 1.9 billion pounds for 1972. 

Viscosity of Resin Solutions as Related to Solvent Properties. A principal function of solvents in coatings is to reduce the viscosity of the resinous binder so that the coating may be applied to the substrate. The proper application viscosity must be attained... 

Uses Solvent in coatings, inks, electrochemistry, polymer and boron chemistry, physical processes such as gas absorption, extraction, stabilization, industrial prods, such as fuels, lubricants, textiles, pharmaceuticals, pesticides diluent in VC dispersions extractant for uranium ores selective solvent for extraction of gold coupling solvent solvent, carrier, stabilizer in pharmaceuticals Features High-boiling inert... 

The role of eoaleseing solvents in coating formulations, the factors which affect the choice of eoaleseing solvents, and the recent developments in esters of low volatility, low odor and rapid biodegradability for use in coating formulations are discussed.
