Abstract: Improved coating formulations containing silica based matting agents in the form of a blend of low pore volume silica particles and high pore volume silica particles are disclosed. The matting formulations are useful in waterborne coating compositions to provide exceptional properties to a coated substrate. Films resulting from the coating formulations containing silica-based matting agents on a substrate unexpectedly provide improved chemical resistance to the surface of the substrate, in particular wood or plastics. Methods of making and using the silica-based matting formulations are also disclosed.

Abstract: A method for synthesizing small crystals of silicoaluminophosphate-34 (SAPO-34) molecular sieves with high structural purity. The method includes first forming a slurry comprising monoisopropanolamine. Then, the slurry is aged to form an aged slurry. Finally, crystallization of silicoaluminophosphate molecular sieves comprising the SAPO-34 molecular sieves is induced from the aged slurry.

Abstract: The present invention is directed to an improved catalyst support and to the resultant catalyst suitable for treating exhaust products from internal combustion engines, especially diesel engines. The support of the present invention is a structure comprising alumina core particulate having high porosity and surface area, wherein the structure has from about 1 to about 40 weight percent silica in the form of cladding on the surface area of said alumina core. The resultant support has a normalized sulfur uptake (NSU) of up to 15 ?g/m2.
