Rubber Cement 

an adhesive obtained by dissolving raw rubber or rubber stock in such organic solvents as gasoline and ethyl acetate.

Practically all types of raw rubber may be used to produce rubber cements. Depending on the temperature at which the adhesion bond is formed during vulcanization, a distinction is made between hot-setting rubber cements, which form at high temperatures, usually over 100°C, and low-setting rubber cements, which form at low temperatures; the latter are also called self-vulcanizing rubber cements.

Rubber cements are prepared by mixing the components in special apparatus called glue mixers. Self-vulcanizing rubber cements are supplied to the consumer in the form of two solutions, which are mixed before the cement is used; one solution contains raw rubber or rubber stock with several ingredients, and the other solution contains a highly active vulcanizing system. The major characteristics of adhesion bonds, which depend mainly on the type of raw rubber used, include resistance to separation, breaking, corrosive mediums, moisture, heat, and frost.

Rubber cement is used in the assembly and repair of rubber and rubberized-fabric items and the production of rubberized fabrics; it is also used to attach rubber to metal, wood, cement, or glass.
