Abstract: Waxes prepared from hydrogenated plant oils, such as palm and soybean, are used to render cellulosic materials resistant to water. Unlike cellulosic materials rendered water resistant with waxes obtained using petroleum-derived or synthetic waxes, the water resistant cellulosic materials prepared using this composition are recyclable using conventional paper recycling methods; the composition is dispersible in warm water solutions. Such water resistant materials are characterized by enhanced moisture barrier properties. The compositions have a low iodine value (between 2-5), and melting points between approximately 120-165 degrees F. (Mettler Drop Point). The wax comprises a triglyceride whose fatty acids are predominantly stearic acid (C18). The composition is used as an additive in the manufacture of wax coated boxes and adhesive compounds used in boxboard packaging and manufacturing operations.

Abstract: A conductive material for use in interior coating of a cathode ray tube (CRT), which includes an aqueous dispersion medium containing potassium silicate and a dispersing agent; and graphite particles. The potassium silicate of the aqueous dispersion medium has a silicon dioxide (SiO2) to potassium oxide (K2O) mole ratio in the range of 4.5:1 to 6:1, and is prepared by adding hydrosilica gel to a potassium silicate aqueous solution having a SiO2 to K2O mole ratio less than 4.5:1. When the conductive material, which uses potassium silicate dispersed in an aqueous dispersion medium with a SiO2:K2O mole ratio in the range of 4.5:1 to 6:1, as a binder, is applied to form a conductive layer on the funnel of a CRT, adhesiveness of the conductive layer markedly increases. Use of the potassium silicate as a binder decreases the amount of gas released during a hot-evacuation process, and thus shortens evacuation time.
