  • Patent number: 10493037
    Abstract: Methods for forming multiphasic microparticles by using wettability engendered template self-assembly (WETS) techniques are provided. A template is used that defines wettable regions to polar and non-polar liquids and non-wettable regions to polar and non-polar liquids. A first liquid is applied to the template and forms a solid or semi-solid release layer. A second liquid is applied over the release layer to form a solid or semi-solid first layer and a third liquid is applied over the first layer to form a solid or semi-solid second layer. The first layer and the second layer can be released from the template by removing the release layer from the template with a treatment agent to form multiphasic microparticles. Methods for making the templates and multiphasic micro particles are also provided.

  • Publication number: 20140000483
    Abstract: The invention relates to a method for the surface treatment of inorganic pigment particles with agglomerates of fine primary particles or single crystals of inorganic compounds, particularly of oxides or sulphates. The method is characterized in that the inorganic compounds are first precipitated from an aqueous solution under suitable pH conditions in a separate vessel in the form of fluffily structured agglomerates and/or single crystals. The precipitation product is subsequently added to an aqueous suspension of inorganic pigment particles. The method is particularly suitable for the surface treatment of titanium dioxide particles, in order to achieve high hiding power or high opacity when used in emulsion paints or laminates.

  • Patent number: 8613799
    Abstract: The present invention relates to dispersants containing at least two lipophilic groups (e.g., alkenyl-substituted acylating agent, such as, dodecyl succinic anhydride), and the dispersants contain a hydrophilic component (e.g., alkylene glycol, polyalkylene glycol) present in an amount sufficient to at least partially disperse the amphiphilic compound in aqueous media (e.g., 30 wt % to 80 wt %). The invention further provides for dispersants as phosphate, sulphonate, and phosphite derivatives thereof. The invention further provides for the use of the dispersants in tinter compositions (e.g., universal tinter) and reduced shade paints.

  • Patent number: 8608906
    Abstract: A method to prepare aqueous furnishes useful as feedstock in the manufacture of very high-mineral content products, particularly paper sheets having mineral filler content up to 90% that display the required physical properties for the intended applications; the furnishes comprise fibrillated long fibers/mineral fillers mixed with anionic acrylic binders and co-additives, in presence or absence of cellulose fibrils; the fibrillated long fibers and cellulose fibrils provide high surface area for greater filler fixation and the reinforcement backbone network that ties all of the product components together; the anionic binders allow rapid and strong fixation of filler particles onto the surfaces of fibrils when mixing is conducted at temperatures higher than the glass transition temperature (Tg) of the binder. The aqueous furnish provides excellent filler retention and drainage during product fabrication.

  • Publication number: 20130274400
    Abstract: 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.

  • Patent number: 8535434
    Abstract: It is describes a material in the form of lithium fluoride powder containing color centers and the method for its preparation, by the formation of color centers based on irradiating the powder with synchrotron radiation (light). The method involves mechanically reducing the size of the particles that form the LiF powder and the formation of color centers therein by its exposure to synchrotron radiation. The so activated powder, which maintains the transparency characteristics of the original material if exposed to sunlight, can find wide use as an additive both in common printing inks and in pigments used in the artistic field to be used for the formation of marks on artifacts for anti-counterfeiting/identification purposes.
