Special-purpose coatings include paints for automotive refinishing and for aircraft and marine applications; these meet technical requirements broadly similar to the requirements for coatings for military needs. Other significant specialty coatings are for industrial maintenance, roof coatings, and traffic striping.

Topcoats provide modest protection and can be used without primer for some indoor applications, such as metal file cabinets and shelving. In applications requiring rigorous corrosion protection, primers, usually based at least partly on epoxy resins, are used.

From page 48... ...
High-solids paints are one of two dominant nonpolluting paint technologies in the United States. New binders were developed that allowed convenient paint application at 50 to 80 weight percent solids content, or 1000 to 250 grams of solvent per kilogram of paint solids (1 to 0.25 pounds of solvent per pound of paint solids)

From page 49... ...
In many applications aqueous coatings provide an option for reducing VOC emissions beyond what can be achieved by high-solids coatings. High-solids coatings formulated partly with exempt solvents can, in some circumstances, provide equal or lower VOC emissions than those typical for waterborne coatings.

From page 50... ...
Reducing the solvent content of paints, reusing emitted solvents, and improving transfer efficiency not only yield environmental benefits but also often provide considerable cost savings. Reducing the costs of waste disposal provides additional economies.
