The following glossary contains terms used commonly in the paint and coatings industry to describe the characteristics, usage and components of paints and coatings. Results for "E"
Ease of application
Characteristics of a paint or caulk that facilitate its application, e.g., spatter resistance, lapping properties, and open time.
Earth Pigments
Those pigments that are obtained from the earth, including barytes, ocher, chalk and graphite.
Earth tones
The natural colors of earth; browns and beiges.
Edging
Act of striping in or painting near the edge of a surface, such as the wall intersection at ceiling, doorway, or window.
Effervescence
An effect in the film caused by rapid solvent release. This "boiling" of solvent causes a pinholed or cratered appearance reducing gloss.
Efflorescence
Whitish powder (salt deposits) that sometimes appears on masonry surfaces; it is carried to the surface by moisture.
Eggshell
An interior paint that has a low lustre, satin-like appearance. Its gloss level is between flat and semigloss.
Elasticity The ability of paint or caulk to expand and contract with the substrate without suffering damage or changes in its appearance. Expansion and contraction are usually caused by temperature and humidity fluctuations.
Elcometer
A trademark and brand name for a magnetic instrument for measuring dry film thickness of coatings applied to steel surfaces.
Electrostatic Spray
The spray application of paint where the particles are charged causing them to be electrically attracted to the grounded surface.
Elastomeric coating
A thick, flexible paint that bridges hairline cracks. It can be stretched repeatedly, and it immediately returns to approximately its original length. It is commonly used on masonry surfaces.
Emulsion
A mixture (usually milky-white) in which one liquid is dispersed (but not dissolved) in another. A latex paint or caulk binder is often referred to as an emulsion, even though it is a dispersion of solid polymer particles in a liquid (water). In Europe, latex paints are often referred to as “emulsion paints.”
Emulsifier
A material which when added to a mixture of dissimilar materials, such as oil and water, will produce a stable, homogenous emulsion.
Embossed paper
Wallpaper with a raised, textured pattern. Embossed wallpapers are useful when installing over imperfect wall conditions, as they will camouflage contours on an uneven wall. Do not use a seam roller on embossed papers because it can flatten or burnish the raised effect and cause a shiny streak to appear.
Embrittlement
Severe loss of ductility of a metal or alloy.
Ending point
The point where the wallpaper stops at an obstacle. Examples include fireplaces, accent walls and kitchen cabinets.
Enamel
Technically, an enamel is a colored varnish, or high gloss paint. Generally, the term is used for high quality, dirt-resistant paints (usually for interior use) that may have a sheen level from satin to glossy. These coatings are used for more demanding applications as in kitchens, bathrooms, etc.
Environmental Protection Agency (EPA)
An agency of the federal government that has the responsibility of protecting the environment.
Epoxy
A two-part compound used to fill holes in damaged wood. Once dry, epoxy patches are very strong and can be sanded, primed and painted.
Epoxy adhesive
Adhesive based on an epoxy (or epoxide) resin or several such resins. They are of limited use in furniture-making but come in handy for quick repairs.
Epoxy Resin
A synthetic resin produced by the reaction of epichlorohydrin and bisphenol. Epoxy resins may be used alone (unmodified) or modified with drying oils (epoxy esters) for coating vehicles.
Erosion
Deterioration of a surface by the abrasive action of moving materials - fluids or particles. This is accelerated by the presence of solid particles or gas bubbles in suspension.
Ester
Compounds formed by the reaction of alcohols and organic acids.
Etching
Scratching or roughening an existing wallpaper surface to prepare it for the application of a wallpaper-removing solution. The etching of the vinyl-coated surface allows the solution to penetrate through the wallpaper and dissolve the old adhesive to aid in the removal of the existing wallpaper.
Evaporation Loss Solvents
A solvent whose volatility is high. Used to reduce the flash-off time of a paint to combat sagging on cool days.
Evaporation Rate
The speed with which a solvent volatizes or evaporates. It is frequently expressed as the time required for 1 cc. of solvent to evaporate after being poured onto filter paper.
Exposure
The intensity, duration and variation in sun, wind and temperature that characterize any particular site.
Extender pigment
A low-hiding, inexpensive pigment that fills out and extends the high-hiding and colored pigments’ capabilities, provides bulk to the paint, and can positively or negatively have an impact on many properties. Some common extenders are clay, calcium carbonate, and silica.
Extender
Ingredients added to paint to increase coverage, reduce cost, achieve durability, alter appearance, control rheology and influence other desirable properties. Less expensive than prime hiding pigments such as titanium dioxide. Examples: barium sulphate, calcium carbonate, clay, gypsum, silica, talc. May also improve coating performance.
Extractives A large number of different organic compounds which can be extracted from wood with polar or non-polar solvents.
External Mix/Atomization
Using air to break up a coating material after it has exited the spray gun nozzle.
Characteristics of a paint or caulk that facilitate its application, e.g., spatter resistance, lapping properties, and open time.
