Abstract: What is disclosed is a process of improving the transparency of cured abrasion resistant coating compositions when basic dispersions of colloidal silica are used. The process involves adding organic acid to either basic dispersions of colloidal silica prior to combining with a mixture containing a Michael adduct or to a mixture containing a Michael adduct prior to combining with basic dispersions of colloidal silica.

Abstract: POROUS MATERIALS HAVING TWO DIFFERENT REACTION SURFACES Porous materials having a dual surface are disclosed. Also disclosed is a method for their preparation. An example of such a material is a silica gel reacted with a reactive silane intermediate such as (CH3)2Si=O and then, with a reactive silane such as to give a dual treated material having -((CH3)2SiO)XH on the exterior surface and on the interior surface of the pores.

Abstract: The present invention provides methods for separating one or more componentsof interest from a sample containing particulates and soluble materials. The methodcomprises the steps of: (a) filtering a sample through silica filter media whose surfacesilanol groups have reacted with one or more silanes, and (b) simultaneously capturingparticulates and binding a soluble component to the silica filter media. The boundsoluble component of interest is subsequently eluted from the silica filter media. In oneembodiment of the invention, unwanted soluble materials are captured by the treatedsilica filter media and desired component of interest is recovered from the flow-through. In another embodiment of the invention, different components of interest are recoveredfrom both the eluate and the flow-through. Preferred treated silica filter media aresilane-treated rice hull ash or diatomaceous earth with functional quarternary ammoniumgroup or functional sulphonate group. Particulates suitable for the present invention, forexample, are microorganisms.

Abstract: Modified silica fillers are prepared by contacting silica with blends or mixtures containing diorganodihalosilanes and tetrahalosilanes in weight ratios of 1:0.1 to 1:2, respectively. While dialkyldichlorosilanes and tetrahalosilanes such as dimethyldichlorosilane and silicon tetrachloride, respectively, are most preferred, the blends or mixtures may also comprise compositions containing other silanes such as mercaptopropyltriethoxysilane.

Abstract: Silica surfaces are contacted with compositions containing organosilicon compounds to prepare modified silica fillers. The compositions contain only organosilicon compounds which are monomeric dichlorosilanes and trialkoxysilanes. The treating compositions may be (i) mixtures or blends of dialkyldichlorosilanes, and trialkoxysilanes free of hydrocarbon or organofunctional groups reactive with silica surfaces, or (ii) mixtures or blends of substituted dialkyldichlorosilanes in which the substituted dialkyldichlorosilanes are free of hydrocarbon or organofunctional groups reactive with silica surfaces, and trialkoxysilanes free of hydrocarbon or organofunctional groups reactive with silica surfaces. These mixtures and blends contain dialkyldichlorosilanes and trialkoxysilanes in a weight ratio of 1:0.1 to 1:2, respectively.

Abstract: Fluorescent organopolysiloxane compounds which bear two or more reactive silicon-bonded sites are useful as durable markers in curable silicone compositions. Having more than one reactive site the compounds participate in the curing reaction of the curable composition and thus do not adversely affect its curing behaviour. The resulting fluorescent curable compositions are particularly useful in the preparation of adhesive-release coatings.

Abstract: The present invention relates to coating compositions containing multifunctional acrylate monomers, organic compounds and colloidal silica. Silanes are absent from these coating compositions. Transparent, abrasion resistant coatings result from the cure, either by ultraviolet light or electron beam radiation, of these compositions.
