Abstract

524,928. Plasters. LEFEBURE, V., ETRIDGE, J. J., HIMSWORTH, F. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 11, 1939, No. 977. [Class 22] A plaster formed of finely divided anhydrous calcium sulphate such as burnt or unburnt anhydrite or dead burnt gypsum together with accelerators such as potassium and zinc sulphates is rendered more adherent to wood by the addition of animal or fish glue, gelatine or gum arabic or other water-soluble natural gum. The glue &c. may be added as a powder to the dry plaster, or in solution in the gauging water. Specifications 21734/94, [Class 70], and 521,997, are referred to.
