Paint and Coatings

One of the earliest forms of comparison. The pigment/binder ratio is the weight ratio of the sum of the pigments (pigments and fillers) to the binder solids.

The point where there is just sufficient binder present within a paint to cover each extender particle with a thin layer and fill all voids between particles.

One of the earliest forms of comparison. The pigment/binder ratio is the weight ratio of the sum of the pigments (pigments and fillers) to the binder solids.

The ratio of the volume of pigment to the volume of total nonvolatile material present in a coating. The figure is usually expressed as a percentage.

Paint consists of four basic components: Resin Pigment Solvent Additives The performance of a coating is influenced by the selection of these components and the relationship between them. Several rations play an important function in the overall performance of a coating.

The Theoretical Spread Rate or coverage of a coating is a function of the coating's solids content. This value is useful in comparing coatings systems. In actual applications, there are losses. The practical spreading rate accounts for these losses. Losses result from application technique, losses to wind and environment, application equipment, and type of the substrate to be coated and substrate surface profile.

Density, boiling point, evaporation rate, and flash point of common solvents

Common Terms used in the paint and coatings industry.

The grind gauge is an instrument that indicates the fineness of grind or the presence of coarse particles and agglomeration in a dispersion. It is commonly used to determine how finely ground the particles of pigment are dispersed in a sample of paint.
