The flow rate of a liquid. The addition of solvents and/or diluents will reduce the viscosity or fluidity of the paint. Paint viscosity must be carefully adjusted and controlled to allow proper atomisation and flow-out.
A measure of the change in the flow rate (viscosity) of a liquid with temperature rise. The higher the viscosity index the smaller is the change in viscosity.
A drive coupling that uses a fluid to transmit drive. Also sometimes a fluid coupling.
The measure of volatile organic compounds (VOC's) in solvent-borne paints. Usually measured as the weight in kilos of non-exempt solvent per tonne of paint.
Readily changes to vapour or gas at ambient temperatures.
The tendency of a liquid to evaporate. Liquids with high boiling points have low volatility and vice-versa. Volatility affects flash-off time and fire hazard consideration.
Electromotive force expressed in volts. Potential difference.
The voltage that is lost when an electrical current passes through a resistance.
An electrical or electronic device to maintain a generator output within a narrow voltage range.
