Patent number: 4716057Abstract: The two components of the putty, one containing the accelerator and the other containing the catalyst, are placed in two separate containers under vacuo. After the preparation is complete the containers are brought first to atmospheric pressure and then to high pressure in order to favor the removal of the two materials from the containers onto the slab to be coated. The two components are then mixed on the slab forming the putty suitable for coating slabs of marble, stone and the like.Type: GrantFiled: September 25, 1986Date of Patent: December 29, 1987Inventor: Marcello Toncelli

Patent number: 4696957Abstract: This invention relates to aqueous "multi-pack" coating compositions, that is, those which comprise at least two discrete components (or "packs") which are mixed prior to application.Prior attempts to provide an aqueous multi-pack composition have failed to provide a suitable combination of the desirable characteristics of adequate "pot-life" (the time for which the mixed components remain workable) and early development of adequate mechanical properties.The compositions of the present invention which provide such a combination consist of a number of components which together comprise a constituent having epoxide groups, a constituent comprising addition polymer in the form of an aqueous dispersion and a constituent capable of reacting with epoxide groups. In an especially preferred embodiment, the aqueous addition polymer dispersion is combined with at least one of the other constituents in the form of a multi-polymer particle dispersion.Type: GrantFiled: July 9, 1985Date of Patent: September 29, 1987Assignee: Dulux Australia Ltd.Inventors: Hilary E. Adeney, Derrard M. Hall
