TABLE OF CONTENTS It is necessary to be familiar with the fundamentals (Weismantel, 1981; Martens, 1974) of paint to understand and intelligently discuss paint or coatings. Like all technologies, paint technology has its own jargon. The terms paint and coatings are sometimes used interchangeably; paint is the older term used before the 1940s (e.g., for painting houses) after which new sophisticated synthesized materials were developed for automobiles and aircraft and called coatings to distinguish them from the vegetable oil-based materials.
A paint is a decorative, protective, or otherwise functional coating applied to a substrate. This substrate may be another coat of paint. Some terms (Gooch, 1993) associated with paint follow:
Dopant (D. doop, adj.). Any thick liquid or pasty preparation used in preparing a surface. Any varnishlike material for water-proofing surfaces.
Paint (M.E., peint, n.). A substance composed of a solid coloring matter suspended in a liquid medium.
Coating (M.E., cote, n.). A layer of any substance spread over a surface; modem synthesized materials, such as polyurethane resins, that replace older paint materials.

The formula lists the ingredients of the paint (Weismantel, 1981): vehicle, solvents, pigmentation, and additives. The basic paint formulation and ingredients are listed in Table 4.1. Amounts are normally stated in units of weight for accuracy.
