  • Patent number: 10161436
    Abstract: A fastener comprises a threaded surface and an adhesive composition at least partially disposed on the threaded surface. The adhesive composition includes an inorganic compound comprising at least one Group 1 metal and at least one Group 13 element and/or Group 14 element. The inorganic compound is present in an amount of at least about 20 parts by weight based on 100 parts by weight of the adhesive composition. A method of making the (coated) fastener comprises the steps of providing a fastener, providing the adhesive composition, and applying the adhesive composition to at least a portion of the threaded surface of the fastener. A method of joining adjacent elements comprises the steps of providing the adjacent elements, providing the fastener, and disposing the fastener adjacent and/or through the adjacent elements. An adhesive, formed by curing the adhesive composition, has excellent physical properties, including adhesive strength and high temperature resistance.

  • Patent number: 9624399
    Abstract: A method for microencapsulating a core material, such as a blowing agent, in a single shell which has demonstrated to be challenging to microencapsulate as an individual component with a single-shell wall deposition using conventional techniques. Single-shell microcapsules of the blowing agent can be formed, minimizing steps involved in the present microencapsulation technique. Also, microcapsules formed by this method provide increased performance in end-use products, including but not limited to characteristics such as product shelf-life, ease of use, and greater expansion properties. A method of making a coating formulation including the microcapsules is further provided, as well as a fastener including the coating.

  • Patent number: 9404015
    Abstract: A coating composition adapted for application on a fastener, the coating composition composed of a binder component composed of a polymeric resin present in the composition at a concentration between 1.0% and 15.0% by total composition weight, wherein the binder component is composed of at least one of a solvent dispersible compound; a reactive cross-linking component present in the composition in an amount between 1.0% and 80.0%; at least one curing agent; optionally at least one expansion agent, wherein at least one of the curing agent or the reactive cross-linking component are physically and reactively isolated from other components of the composition.

  • Publication number: 20150056394
    Abstract: A coating composition for forming an anti-spatter coating on a substrate is disclosed. The coating composition comprises a ceramic precursor, a curing agent, and optionally a cross-linkable resin. A coated article is also disclosed which comprises a substrate and the anti-spatter coating disposed on a surface of the substrate. The anti-spatter coating is the reaction product formed by curing the coating composition.
