Abstract
308,560. Worldecho, Ltd. March 23, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Sizes.-A solution for coating or impregnating paper or other fibrous sheets or for use as a binder in the manufacture of plastic compositions containing for example sand, asbestos, heavy spar, ashes, sawdust or cotton fibre is made by mixing an alcoholic solution of #-naphthol " or diamine " with phenol or resorcinol, formaldehyde, resins such as shellac, colophony and sandarac, the proportions of which affect the hardness and flexibility of the product, and kerosene or benzene, warming to 50‹ C. and adding sodium sulphite. The mixture is then warmed if necessary to 80‹-85‹ C. and quickly cooled to 30‹-20‹ C. This solution may be mixed with water, milk of lime solution or aqueous solutions of colouring substances. The compositions are moulded in a press at 180‹-200‹ C. Paper to be coated or impregnated is moistened before being pressed.
