Abstract:
Coating compositions that provide hydrophilic and anti-freeze properties are disclosed. The coatings include at least one hydrophilic agent bound to one or more coating components, such as a rheology modifier, a surfactant, a coalescing agent, and a pigment. The hydrophilic agents are attached to the coating components covalently.
Abstract:
Hydrophilic, self-cleaning coating compositions and methods to make and use the compositions are disclosed. The coatings comprise perlite and/or expanded perlite that are activated with hydrophilic agents. The perlites when incorporated in paints provide hydrophilic, self-cleaning and/or biocidal property to the coating.

Abstract:
Paints and coatings that change the coated surface from hydrophobic to a hydrophilic, self-cleaning surface when exposed to atmosphere are described. The compositions include a plurality of boronic acid functionalized polymers, and a blocking agent contacting at least one of the plurality of boronic acid, wherein the blocking agent is configured to be removed by a stimulus to provide a renewable hydrophilic, self-cleaning polymer coating.
Abstract:
A container may have a first component configured to contain one or more articles, and a second component configured to confine the one or more articles contained in the first component where at least one of the first component and the second component have at least a portion made from a material having a negative thermal expansion coefficient.
Abstract:
Functionalized microspheres for being dispersed in matrix materials to reduce the density and weight of the materials may be configured to include a covalently bound surface component which is configured to covalently bond with the matrix material so that when combined with the matrix material a strong, light-weight matrix material may be produced.
Abstract:
Hydrophilic coating compositions and methods to make and use the compositions are disclosed. The compositions include a polymer comprising a plurality of isocyanate groups and a blocking agent contacting at least one of the plurality of isocyanate groups.
Abstract:
Hydrophilic coating compositions and methods to make and use the compositions are disclosed. The compositions include a polymer comprising one or more cyanate groups and a blocking agent contacting at least one of one or more cyanate groups. When exposed to atmospheric water, the blocked cyanate moieties at the surface may hydrolyze to expose hydrophilic groups. Thus, the hydrophobic polymeric surface may change to a hydrophilic surface upon reacting with atmospheric water and moisture.
