39 results about "ZINC OLEATE" patented technology

It is a light tan color powder containing about 8.5-10.5% zinc. Zinc oleate may appear as bloom on the surface of oil or alkyd paints when it is formed by the reaction of oleic acid with zinc white pigment. Zinc oleate is also used as a drier in paints, resins and varnishes.

Performance Grade Asphalt Composition and Method of Production Thereof

An asphalt material having improved paving characteristics and processes for its preparation. An asphalt base material is heated in a mixing chamber to a temperature sufficient to melt the asphalt so that it can be stirred. A water-insoluble heavy metal soap is incorporated into the chamber in an amount effective to reduce the PAV-DSR temperature of the asphalt base material by an incremental amount of at least 1° C. Thereafter, the asphalt material is recovered from the mixing chamber to provide an asphalt product containing the heavy metal soap which exhibits a PAV-DSR temperature which is less than the PAV-DSR temperature for the corresponding base material without the addition of the heavy metal soap. The water-insoluble soap is a C14-C18 heavy metal soap such as a C16-C18 zinc- or calcium-based soap including zinc stearate, zinc oleate and zinc palmitate. The heavy metal soap is added to the mixing chamber in an amount within the range of 0.05-3.0 wt. % of the amount of asphalt based material in the mixing chamber. A thermoplastic polymer may be added to the asphalt based material to provide a polymer-modified asphalt blend. An asphalt paving composition comprising an asphalt base material and a water-insoluble heavy metal soap in an amount to provide a PAV-DSR temperature lower than the PAV-DSR temperature of the corresponding asphalt material without the addition of the heavy metal soaps.
