r/V r UNION CARBIDE ASBESTOS T-135 OPACIFYINe AGENT APPLICATION BULLETIN PLAINTIFF'S EXHIBIT ASBESTOS T-135 OPACIFYING AGENT UC-2564 a highly efficient opacifying agent now in mill use. Excellent performance in both dry and waxed or oiled opacity make it useful in offset, envelope, map, book, glassine, pouch, and saturating papers. a unique UNION CARBIDE development, a specially titanated high purity asbestos fiber on which T1O2 is fixed in finely divided form along the filament. It max imizes the light scattering power of Ti02 by achieving unusually high retention in the dispersed state without agglomera tion^ Kubelka-Munk tests show T-135 more than doubles the scattering power of Ti02 in the sheet over a broad range of addition. ff/ectron photomicrograph (5,600 X} of Asbestos T-J35 showing omform distribution of Ti02 on asbestos fiber. positively charged, the most highly re tained pigment known. low cost, less than 70 per cent that of Ti02 per pound. Direct substitution in quality paper grades can save up to $15 per ton of product paper. Economic amounts can be used to improve opacity/ ash ratios in sheet where T1O2 costs are prohibitive. avaifable commercially in carload quan tities, in a convenient dust-free pellet form.

Add T-135 pellets to the beater; the energy requirement to repulp T-135 pellets is less than to defiberize pulp lap. Reduce, or preferably eliminate, organic retention aids: T-135 performs this secondary function. T-135 can be used in both acid and alkaline systems. 8 2 UCC 023284 r' ASBESTOS T-135 OPACIFYING AGENT SOME TYPICAL T-135 MILL PERFORMANCE T-135 has proved itself in more than 40 mills. Examples of mill data tabulated below, indicate the savings using improved T-135 based pigment-filler systems to produce specification grade paper. In some cases specifications were exceeded, indicating opportunity for further cost optimization.

Often yields wax pick increase for starch-sized sheets. Markedly improves solids recoveries in the saveall, reducing loss in mill effluent. . 3 UCC 023285 ASBESTOS T-135 OPACIFYING AGENT TYPICAL PROPERTIES OF T-13S Ash.............................
