    摘要: The invention relates to a method of producing a stable substantially aqueous silanized colloidal silica dispersion having a silica content of at least about 20 wt %, comprising mixing at least one silane compound and colloidal silica particles, wherein the weight ratio of silane to silica is from about 0.003 to about 0.2. The invention also relates to a dispersion obtainable by the method, and to a stable substantially aqueous silanized colloidal silica dispersion having a silica content of at least about 20 wt %, wherein the weight ratio of silane to silica is from about 0.003 to about 0.2. The invention further concerns the use of the dispersion for coatings applications and as an additive.

    摘要: Micronized perlite filler product, methods of producing the micronized expanded perlite products, and methods of use thereof are provided. The micronized expanded perlite product has, for example, a small median particle size (for example, less than 11 microns), a high blue light brightness (for example, higher than 84) and low oil absorption (for example, less than 70 percent in volume). The micronized expanded perlite product may be used in a variety of applications such as anti-block filler in plastic films and reinforcement filler in polymers.

    摘要: A resin-impregnated porous filler having meso-pores, micro-pores, and macro-pores is obtained by inserting a coupling agent or an inorganic material between layers of a stratified clay mineral to prepare a crosslinked structure between the layers; making the stratified clay mineral three-dimensional; and impregnating the macro-pores with resin.
