  • COATINGS FOR INCREASING COLOUR VIBRANCY AND METHODS OF APPLYING SAME
    Publication number: 20170066934
    Abstract: A coating for application to a natural-coloured substrate is provided that allows for increased colour vibrancy of dye applied to the coated substrate. The coating comprises silica particles and at least one binder solid, and in addition, may comprise siloxane. The coating may comprise a mono or a poly aqueous sol dispersion of silica particles optionally having particle sizes from about 1 to about 150 nm.

  • Method and composition for treating fibrous substrates to impart oil, water and dry soil repellency
    Patent number: 6225403
    Abstract: The present invention relates to a method and composition for treating textile fibers or substrates, to thereby impart oil, water and soil repellency at substantially reduced add on levels of fluorine containing resins based on weight of the textile fiber or substrate so treated.

  • Grip and friction enhancement compositions
    Patent number: 5886089
    Abstract: The gripping characteristics of the contact surface of a sole, a grip, handle, glove or the hand are enhanced by having applied thereto an aqueous mixture of:a) a fluoroalkyl acrylate copolymer emulsion; andb) a silicone polymer micro emulsion;and allowing said applied aqueous mixture to dry thus forming a thin film or a thin treated layer of either a continuous or discontinuous nature which imparts enhanced gripping characteristics to the substrate.
