|
efflorescence
|
A white alkaline powder deposited on the surface of stone, brick, plaster, or mortar and caused by leaching.
|
|
|
Enamel
|
Broad classification of paints that dry to a hard, usually glossy finish.
|
|
|
Epoxy
|
Extremely tough and durable synthetic resin used in some coatings.
|
|
|
Extenders
|
Ingredients added to paint to increase coverage, reduce cost, achieve durability, and alter appearance. Less expensive than prime hiding pigments such as titanium dioxide.
|
|
|
Flagged bristles
|
split ends
|
|
|
Gloss
|
Luster. The ability of a surface to reflect light. Measured by determining the percentage of light reflected from a surface at certain angles.
|
|
|
Sympsum board
|
Thin slabs of plaster covered with a heavyweight 100% recycled paper covering.
|
|
|
Intumescent
|
A mechanism whereby fire-retardant paints protect the substrates to whcih they are applied. An intumescent paint puffs up when exposed to high temperatures, forming an insulating, protective layer over the substrate.
|
|
|
Reduction
|
Lowering the viscosity of a paint by the addition of solvent or thinner.
|
|
|
Spectrophotometer
|
An instrument used for comparing the color intensities of different spectra.
|
|
|
Substrate
|
Any surface to which a coating is applied.
|
|
|
Surfactant
|
A surface active agent.
|
|
|
Titatanium dioxide
|
A white pigment providing the greatest hiding power of all white pigments. Nontoxic and nonreactive.
|
|
|
Tooth
|
The slight texture of a surface that provides good adhesion for subsequent coats of paint.
|
|
|
Urethane.
|
An important resin in the coatings industry.
|
|
|
Vehicle
|
Portion of a coating that includes all liquids and the binder.
|
|
|
Viscosity
|
The resistance to flow in a liquid. the fluidity of a liquid such as water has a low viscosity and molasses a very high viscosity.
|
|
|
0-25 flame spread
|
Lowest acceptable flame retardant rating for commercial and public buildings.
|
|
|
Fire retardant
|
A coating that (1) reduces flame spread, (2) resists ignition when exposed to high temperature, or (3) insulates the substrate and delays damage to the substrate.
|
|
|
Mils.
|
Measurement of thickness of film. One one-thousandth of an inch. One mil equals 25.4 microns (micrometers).

|
|
|
Hiding power
|
The ability of paint film to obscure the substrate to which it is applied. Measured by determining the minimum thickness at which film will completely obscure a black and white pattern.
|
|
|
Efflorescence
|
A white alkaline powder deposited on the surface of stonek, brick, plaster, or mortar and caused by leaching.
|
|
|
Abrade
|
To scrape or rub off a surface layer
|
|
|
Acrylic
|
A synthetic resin used in high performancy, water-based coatings.
|
|
|
Alkyd
|
Synthetic resin modified with oil.
|
|
|
Binder
|
Solid ingredients in a coating that hold the pigment particlesw in suspension and attacdh them to the substrate. Consists of resins (oils, alkyd, latex). The nature and amount of binder determines many of the nature and amount of binder determines many of the paint's performance properties - washability, toughness, adhesion, color retention, and so on.
|
|
|
Bleed.
|
When color penetrates through another coat of paint.
|
|
|
Calcium carbonate.
|
An extender pigment.
|
|
|
Chroma
|
A measurement of color; the degree of saturation of a hue.
|
|
|
DFT
|
Dry film thickness. The mil thickness when coating has dried.
|
|
|
Coverage according to method of application:
