Binder

An earlier Microsoft Office workbook file that let users combine related documents from different Office applications. The documents could be viewed, saved, opened, e-mailed and printed as a group. Binder was an ActiveX Documents container, and Office applications were ActiveX Documents servers. The documents were ActiveX Documents objects, formerly known as DocObjects. Introduced with Office 97, Binder was dropped in Office XP. See ActiveX Documents.

binder [′bīn·dər]

(materials)

A resin or other cementlike material used to hold particles together and provide mechanical strength or to ensure uniform consistency, solidification, or adhesion to a surface coating; typical binders are resin, glue, gum, and casein.

binder

1. A cementing material, either hydrated cement or a product of cement or lime and reactive siliceous material, for holding loose material together.

2. A component of an adhesive composition that is primarily responsible for the adhesive forces which hold two bodies together.

3. A binding agent.

4. A soil binder.

5. A binding joist.

6. A binding stone.

7. Any member which binds together components of a framing structure.

Binder 

any of a group of materials that cause cohesion of grains of silica sand or other fillers used in making foundry molds or cores. The binder ensures the necessary strength of the core or mold. The film of binder applied to the surface of the filler grains is hardened either by heating the mixture or by the action of external agents.

Binders fall into three classes: anhydrous organic binders (linseed oil, drying oil), hydrous organic binders (synthetic resins, sulfite residues [liquor], molasses), and hydrous inorganic binders (molten glass, cement, foundry clay). Binders can also be classified according to the type of hardening as those with irreversible hardening (drying oil, ethyl silicate, synthetic resins), intermediate hardening (sulfite residues [liquor], dextrin), and reversible hardening (rosin, foundry clay).

Binders with irreversible hardening produce mixtures that exhibit a tensile strength when dry of more than 0.5 meganewton per sq m (MN/m²), or 5 kilograms-force per sq cm, assuming 1 percent binder in the mixture. Binders with intermediate hardening produce mixtures with tensile strengths in the range 0.3–0.5 MN/m², and mixtures made from binders with reversible hardening have strengths up to 0.3 MN/m².
