  • Patent number: 8758854
    Abstract: To obtain a sugar-plum shaped composite particle, a reaction vessel with 300 parts by weight of water placed therein is charged with 30 parts by weight of polymethyl methacraylate resin particles of 2 ?m average particle diameter, and ultrasonic waves are applied to the mixture for 1 minute to obtain a particle dispersion liquid. Subsequently, 15 parts by weight of methyltrimethoxysilane is added to the dispersion liquid to obtain methyltrimethoxysilane hydrolyzates in the dispersion liquid. Thereafter, 10 parts by weight of 1 weight % aqueous ammonia is added thereto and agitated. One minute later, the agitation is discontinued, and the mixture is allowed to stand still for 10 hours to effect maturation. The resultant mixture is filtered and dried to obtain sugar-plum-shaped particles provided on their surfaces with polyorganosiloxane projections.

  • Patent number: 8741432
    Abstract: Coated particles comprise a core of fumed or precipitated inorganic metal oxide having a surface area of about 50 to about 500 square meters per gram and a shell consisting of an array of fluoroalkyl molecular chains at a density of at least 1 chain per square nanometer, joined to the core by covalent chemical bonds and with a total organic content of at least 9.9 percent by weight. These particles are formed by the chemical attachment of fluoroalkyl-alkylsilanes after exposure to an alkylamine and followed by an extraction to remove any organic material not covalently bound. The dense packing of molecular chains in the fluoroalkyl shell combined with a mesoporous structure imparts a very low surface energy, a very high specific surface area, and surface texture over a wide range of length scales. Such features are highly desirable for the creation of, for example, superhydrophobic and superoleophobic surfaces, separation media, and release films.

  • Patent number: 8685159
    Abstract: An adhesion bond strength enhancer for cementitious adhesive mortar is disclosed. The adhesion enhancer improves bond strength between the mortar and relatively hydrophobic plastic material, such as extruded polystyrene boards and expanded polystyrene boards of the type generally employed in Exterior Insulation Finishing Systems (“EIFS”). Preparation of non-caking, free-flowing, solid dialkyl sulfosuccinate compositions for use as the adhesion enhancer is also disclosed. The adhesion enhancer is attractive for large-scale application in mineral mortar dry-mixes or other solid construction materials. The invention can be used to improve the strength of an adhesive bond between a) gypsum based plaster or stucco and concrete or bricks, b) tile adhesives and concrete, and c) mineral mortars on polystyrene boards, among others.
