Electro-magnetically activated electrical switch.

A valve operated by a solenoid. Fuel injectors are good examples.

The part of the paint that does not evaporate but stays on the surface to form a film. Usually measured on a weight or volume basis.

Homogeneous liquid or mixture of two or more chemical substances.

The ability of a liquid to dissolve a solid. Measured by the viscosity of a solution at a certain concentration of solid resin. The same solvent may have different solvency for different resins.

A liquid which will dissolve another material, usually resins or other binder components. Commonly organic liquids.

The weight per unit volume of a solvent or solvent mixture.

The particular mixture of liquids (usually true solvents and diluents) that give a paint the desired flow or evaporation properties.

Describes a paint which contains organic solvents rather than water as its primary liquid component.

Bumps or small craters that form on the paint film, which are caused by trapped solvent trying to escape through the drying paint.
