A binder is a material used to bind together two or more other materials in mixtures.

Its two principial properties are adhesion and cohesion. Adhesion is the molecular attraction exerted between bodies in contact. ... In computer programming, cohesion is the degree to which each part of a module is associated with each other part, in terms of functional relation. ...

Rocket fuel is the propellant which is burned to produce thrust in rockets. ...

In composite materials, epoxy, polyester or phenolic resins are common. In reinforced carbon-carbon, plastic or pitch resin is used as a source of carbon released through pyrolysis. Transite used cement as a binder. Epoxy or polyepoxide is a thermosetting epoxide polymer that cures when mixed with a catalyzing agent or hardener. Most common epoxy resins are produced from a reaction between epichlorohydrin and bisphenol-A. The first commercial attempts to prepare resins from epichlorohydrin occurred in 1927 in the United States. ...
