STABLE MIXTURES OF COLLOIDAL SILICA AND A FILM-FORMING POLYMER |
摘要 |
Binder compositions are disclosed that include silica aquasols having silica that is metal-modified to include a monolayer or less of a metal such as aluminum, tin, zinc or lead, and deionized to a pH of 2,5-7.0 and a water soluble polymer such as poly(vinyl alcohol). An adhesive that includes a silica aquasol, an oxygen-moiety containing polymer, and clay, the surface of the silica being modified to include a metal, and the silica aquasol being deionized to a pH of 2.5 to 7. |
