  • Patent number: 12203006
    Abstract: Improved silica-based matting agents are disclosed. The matting agents are useful in waterborne coatings composition to provide exceptional properties to a wood based substrate. Films resulting from the silica-based matting agents on a wood substrate unexpectedly provide improved chemical resistance and/or film clarity to the surface of the wood substrate. Methods of making and using the matting agents are also disclosed.

  • Patent number: 11643481
    Abstract: The present invention provides polymer compositions having improved corrosivity, color stability and clarity. Also disclosed is a process of preparing the polymers. The process may comprise incorporating into the polymer an acid neutralizing amount of an amorphous aluminum silicate. The amorphous aluminum silicate may be present in the polymer in an amount such that the polymer composition having a Corrosivity Index of less than 6. A refractive index of the amorphous aluminum silicate may be the same or substantially the same as a refractive index of the polymer.

  • Publication number: 20220298365
    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.

  • Patent number: 10137428
    Abstract: Disclosed are silica bound zeolite adsorbent particles which possess high volumetric gas adsorption capacity for the adsorption and/or desorption of gases. The adsorbent are highly effective as a gas source in volumetrically constrained applications. The silica-bound zeolite adsorbents possess a relatively high zeolite content simultaneously with a relatively low intra-particle pore volume as compared to the clay bound zeolite aggregates heretofore used as a gas source in volumetrically constrained environments, e.g. instant beverage carbonation processes, devices or systems.
