Abstract
Abstract In a composition of a type furnished in two separate parts, which are mixed together just prior to use as, for example, an adhesive, there is provided a first component containing a monomeric base consisting of at least one of the class of vinyl compounds which are available in liquid or solid form, and a metal chelate compound selected from among Beta -diketone chelates and ketoester chelates of various metals. A second component is provided which also includes a monomeric base consisting of at least one of the aforesaid class of vinyl compounds, and a peroxide which, by itself, does not cause the latter monomeric base to harden at room temperature. The first and second components may each contain further a stabilizer and, if desired, a hardening accelerator as additives.
