20080242548 | Method of microencapsulating an agricultural active having a high melting point and uses for such materials - A method of producing a controlled release form of an agricultural active material includes the provision of an organic liquid composition in which the active is present, but where the liquid composition is free from aromatic solvents and is maintained below the normal melting point of the active. The liquid composition is formed into small droplets and the droplets are enclosed by a non-water soluble shell to provide microcapsules, the shell of which is designed to release the agricultural active at a pre-selected controlled rate when the microcapsule is exposed to natural environmental conditions. Controlled release forms of agricultural actives are also provided. | 10-02-2008 |
20090275699 | Starch containing formaldehyde-free thermoset binders for fiber products - Binder compositions are described that include a carboxyl-containing polymer, a cross-linking agent, and a starch compound having a molecular weight greater than about 10,000 g/mol. In addition, fiber products are described that include mineral or polymeric fibers and a binder prepared from an aqueous composition that includes a carboxyl-containing polymer, a cross-linking agent, and a starch having a molecular weight greater than 10,000 g/mol. | 11-05-2009 |
20100286343 | Surfaces containing coupling activator compounds and reinforced composites produced therefrom - The invention relates to products and processes employing coupling activator compounds represented by the following formula I: | 11-11-2010 |
20110180957 | SURFACES CONTAINING COUPLING ACTIVATOR COMPOUNDS AND REINFORCED RESINS PRODUCED THEREFROM - The invention relates to products and processes employing coupling activator compounds represented by the following formula I: | 07-28-2011 |
20130040108 | MODIFIED FIBERS FOR USE IN THE FORMATION OF THERMOPLASTIC FIBER-REINFORCED COMPOSITE ARTICLES AND PROCESS - A surface-modified fibrous material is provided for incorporation in a thermoplastic matrix to form a fiber-reinforced composite article. Good binding between the fibrous material and the thermoplastic matrix is achieved through the presence of finely roughened surfaces on the fibers of nanoparticles of an inorganic material. Such nanoparticles are provided from an alkaline aqueous size composition containing the nanoparticles dispersed therein (as described). The fibrous material may be provided in continuous or discontinuous form. In a preferred embodiment glass fibers are initially provided in continuous form followed by cutting into discontinuous lengths and drying with the retention of the nanoparticles on the surfaces of the fibers. The surface-roughened fibrous material is incorporated in a thermoplastic matrix as fibrous reinforcement with the application of heat whereby the thermoplastic matrix is rendered melt processable. In preferred embodiments injection or compression molding is utilized. Improved long-fiber thermoplastics also may be formed to advantage. | 02-14-2013 |
