Abstract:
Coating compositions, methods and articles of manufacture comprising a nanoparticle system employing same to impart surface modifying benefits for all types of soft surfaces, and in some cases, hard surfaces, are disclosed. In some embodiments, dispersement of nanoparticles in a suitable carrier medium allows for the creation of coating compositions, methods and articles of manufacture that create multi-use benefits to the modified surfaces. These surface modifications can produce long lasting or semi-permanent multi-use benefits that, in some embodiments, may include at least one of the following improved surface properties: cleaning, wettability, liquid strike-through, comfort, stain resistance, soil removal, malodor control, modification of surface friction, reduced damage to abrasion and color enhancement, relative to the surfaces unmodified with such nanoparticle systems.
Abstract:
Metal pigment particles are treated with a product resulting from the reaction between an organic phosphonic acid with an amine having at least one organic group containing at least six carbon atoms to inhibit their reactivity to water. The treated metal particles can be used in coating and ink compositions. Additionally, the treated metal particles can be used to formulate pastes and dispersions that are provided to a coatings manufacturer.
