Patent number: 9955700Abstract: Antimicrobial chemical compositions comprise an aluminum phosphate (AlP) solid dispersed within a binding polymer, wherein one or more bioactive materials are disposed within AlP forming a bioactive-AlP complex. The complex may comprise the bioactive material chemically bonded with the AlP, physically combined with the AlP, or a combination of both. The complex may be formed according to precipitation, condensation and sol-gel methods of forming. The complex is engineered to provide a controlled delivery of the bioactive material or a constituent thereof upon exposure to moisture to give a desired level of antimicrobial resistance to a film or composite formed from the composition of at least about 30 ?g/m2, and may also provide a desired degree of corrosion resistance through the release of passivating phosphate anion.Type: GrantFiled: October 13, 2015Date of Patent: May 1, 2018Assignee: BUNGE AMORPHIC SOLUTIONS LLCInventor: Raymond E.

Patent number: 9611147Abstract: APs are made by binary condensation via base-to-acid or acid-to-base routes. In the base-to-acid route, an aluminum hydroxide slurry is added to phosphoric acid that reacts to produce an aluminum phosphate condensate. In the acid-to-base route, phosphoric acid is added to an aluminum hydroxide slurry that reacts to produce an aluminum phosphate condensate. In an alternative base-to-acid route, an acidic aluminum phosphate is first made by adding phosphoric acid to a first amount of aluminum hydroxide slurry, and such acidic aluminum phosphate is added to a remaining amount of aluminum hydroxide slurry to react and produce an aluminum phosphate condensate. The reactions can be controlled to form an in-situ layered aluminum phosphate. So-formed APs can be amorphous, crystalline, or a combination thereof, and have low oil absorption and surface area, making them particularly useful in such end-use applications as extender pigments in coating compositions, replacing up to 70 wt % of TiO2.Type: GrantFiled: April 16, 2012Date of Patent: April 4, 2017Assignee: Bunge Amorphic Solutions LLCInventors: Raymond E.
