    摘要: A hydraulic dental cement composition which comprises a mixture of a dental cement powder having silicon oxide for its essential constituent and a setting agent powder having polyacrylic acid for its essential constituent is disclosed. This composition is of high compression strength due to the silicon dioxide contained therein, and its own pulverulence makes it excellent in workability because it has only to be kneaded with water to be placed into a useable form. Addition of zinc oxide or the like enhances the resistance to deterioration of the composition.

    摘要: Double fluid hardening resion compositions are hereby offered which contain a hardening resin base composed of bisphenol A epoxy resion and paraoxybenzoic glycydylester-ether epoxy resin and a hardening agent constituted by a complex of a polybasic carboxylic ester derived from an alcohol having a cyclic ether linkage in its molecule and boron trifluoride. These compositions are capable of very quick setting of resin and their hardened form possesses excellent physical properties, so that they are useful for urgent repairs of pipings, tanks, etc.
