  • Publication number: 20220348502
    Abstract: An aqueous dispersion and uses therefor. The aqueous dispersion includes a Component (a), Component (b) and Component (c). Where Component (a) is a polymer prepared by the polymerization of monomers comprising a vinyl ester and an ethylene, where Component (b) is an acrylate-based polymer and where Component (c) is water. A film that is formed from the aqueous dispersion has a glass transition temperature of less than or equal to ?7° C. The aqueous dispersion the polymer of the Component (a) has a pot life of longer than or equal to 4 hours after being mixed with cement. Where Component (a) is present in an amount of higher than 35%, based on the total weight of the aqueous dispersion and Component (b) is present in an amount of less than or equal to 20%, based on the total weight of the aqueous dispersion.

  • Publication number: 20130298311
    Abstract: Embodiments herein provide pants with an integrated pants closure system for securing the pants to a waist of a user. The closure system may provide a plurality of points of closure, such as a belt, a fly, and an internal panel closure. The closure system may provide a low-profile for a front portion and/or waistband of the pants. Additionally, the closure system may provide backup points of closure in case of failure. The belt may include a buckle with a finger that extends through a loop in the belt to close the belt. The fly may include a zipper that extends to a top edge of the waistband. The internal panel may include one or more low-profile snaps to secure the internal panel to an inside surface of the pants and/or waistband.
