Colorless ink. It causes pigmented ink to become more transparent.

A pigment which contributes very little hiding to the system, but does reinforce the film and alter the gloss.

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.

A low-hiding, inexpensive pigment that fills out and extends the high-hiding and coloured 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.

Organic material used to improve polymer properties. Syn. Filler

A less-expensive ingredient than titanium dioxide that fills out and extends the pigment's capabilities. Extender cannot be used without pigment. Some common extenders are clays, calcium carbonate, and silica.

A solid material used as an additive to impart other specific physical properties to a coating; They are often natural minerals such as talc, kaolin, whiting etc. The preferred term is generally “extender”. The term is derived from the term “pigment extender” as they are generally pigment-like in nature but possess poor optical properties. Pigments themselves are generally too expensive to use to modify properties other than colour. An example of a case where both pigmentation and other properties are filled by the same substance would be a red oxide primer. See also See also seale, size, filler, bonding liquid, undercoat.

A pigment of low hiding power, used principally to "extend" or make paint go further and to bind together pigment particles of various shapes. Used because of its physical or chemical properties.

Inexpensive and inert pigment added to paint for bulk and to lower costs.

Pigment which provides very little hiding power but is useful in stabilizing suspension, improving flow, lowering gloss, and providing other desirable qualities; generally low in cost.

Material used to improve polymer properties. Syn. Filler, Reinforcer

A substance added to an ink to improve is working quality or to extend the volume.

Those parts of a letter, which extend above the x-height or below the baseline. An ascender or descender. Also, a substance added to ink that will increase the latter's viscosity. See ASCENDER DESCENDER VISCOSITY

Supplementary fuel derived from sources other than oil and added to petrol.

A material added to a plastic compound used to reduce the amount of resin required per unit volume.

A material used to increase the volume of a coating without thinning and without affecting the properties of the coating other than diluting the color intensity.

A chemical compound add to ink to increase its volume without changing it viscosity.

A very concentrated solution of corrosion inhibitors to be added to used coolant to refortify some of those inhibitors that deplete. An extender does not contain a full complement of inhibitors but only those that are known to deplete. Unlike SCA's and chemical filters, extenders are typically used only once in the life of the coolant, typically after 300,000 miles of service.

Ascenders and descenders are collectively known as extenders. Font: Historically, a font is a typeface in a specific style and point size. Example: Times Bold 12 point is a font. Times Bold is a typeface; Times Bold 12 point is a font, and Times Bold 10 point is another font of the same typeface. Current practice allows font to be used to refer any typeface that can be rendered in a number of different sizes; e.g., someone will say that a piece has been set in the Times Bold font.

The term extender is sometimes applied to resinous materials added to such system as epoxy may be referred to as “diluents”.

A medium added to paint to slow its drying time or make a color more transparent without watering down the color. Also called "retarder".

Descenders and ascender; i.e., the parts of the letterform that extend below the baseline (p, q) or above it (b, d).

An organic material used to increase the volume and lower the cost of a sealant or adhesive.

A material added to a compound to lower cost with minimal degradation of properties.

A substance added to a plastic composition to reduce the amount of the primary resin required per unit volume.

An available or relatively inexpensive compatible material which can be added to a more valuable substance so as to increase the amount of material in useful form. The use of extenders may involve adulteration under some conditions.
