There are generally three components to a paint: binder, diluent and additives. However, only the binder is absolutely required. The binder is the part which eventually solidifies to form the dried paint film. The diluent serves to adjust the viscosity of the paint. It is volatile and does not become part of the paint film. Anything else is an additive.
Typical binders include synthetic or natural resins such as acrylics, polyurethanes, polyesters, melamines, oils, or latex. Typical diluents include organic solvents such as alcohols, ketones, esters, glycol ethers, and the like. Water is a common diluent. Sometimes volatile low-molecular weight synthetic resins also serve as diluents. Typical additives include pigments, dyes, catalysts, thickeners, stabilizers, emulsifiers, texturizers, adhesion promoters, flatteners (de-glossing agents), and the like.
After application, the paint solidifies and becomes tack-free. Depending on the type of binder, this hardening may be a result of curing (polymerization), evaporation, or even cooling. In oil-based paint, curing takes the form of oxidation, for example oxidation of linseed oil to form linoxin to create a varnish. Other common cured films are prepared from crosslinkers, such as polyurethane or melamine resins, reacted with acrylic polyester or polyurethane resins, often in the presence of a catalyst which serves to make the curing reaction proceed more quickly or under milder conditions. These cured-film paints can be either solvent-borne or waterborne. Other waterborne paints are emulsions of solid binders in water (in fact, such paints are often called simply "emulsions"). When the diluent evaporates, the molecules of the binder coalesce to form a solid film. Such emulsion paints are also known as latex paints because the polymer is formed through an emulsion polymerization through which the monomers are emulsified in a water-continuous phase. The polymer itself is not soluble in water and hence the paint is water resistant after it has dried. Residual surfactants in the paint as well as hydrolytic effects with some polymers cause the paint to remain susceptiable to softening and, over time, degradation by water. Still other films are formed by cooling of the binder. For example, encaustic or wax paints are liquid when warm, and harden upon cooling. Aerosol paint is paint contained in a pressurized aerosol spray can used for spray dispensing. Uses range from simple covering of things such as bare metal, touch-ups on various things to the more in depth graffiti or stencil art. Popular Brands are Krylon, Rust-o-leum, Belton, and Montana (however Montana and Belton Paints are primarily used only for artistic purposes). By using different tips, or valves, the thickness and opacity of the paint can be changed. Furthermore various artistic brands (such as Montana and Belton) produce paints in both the standard high pressure can, which allows for faster and thicker coverage, and in low pressure cans, which provide for more control and some more artistic flexability, although they normally require more coats of paint. Most Aerosol paints have a metal, glass or plastic ball bearing inside of the can, which is used to stir(mix) the paint without touching it. Many street artists, or "taggers" use aerosol paint as an art medium. Many people refer to art using Aerosol paints as a medium as "Graffiti"
