Consists of white or colored solids suspended in liquid, which when applied to a suitable surface, generally form a continuous solid film by oxidation or evaporation.

is the solid portion of paint, the finely divided solid particles used in paint.

are inert materials which are added to the paint to increase the volume without duly increasing the cost.

in paint, _______ is the media that bind the pigment together in a uniformly dispersed manner to hold the pigments to the substrate with the binder itself to give a protective and decorative finishes.

is the liquid portion of paint.

Is the hard oil soluble class and is made compatible and homogeneous with the oil by means of heat.

The volatile portion of the vehicle includes liquids that actually dissolve nonvolatile ingredients of the vehicle.

Are volatile solvents, it acts as a suspending agent. They cause the paint to flow better, they evaporate when the paint is applied.
