  • Publication number: 20190016935
    Abstract: Adhesive composition including an elastomeric silicone-based copolymer selected from the group consisting of urea-based silicone copolymers, oxamide-based silicone copolymers, amide-based silicone copolymers, urethane-based silicone copolymers and mixtures thereof; and greater than 0% by weight and no more than 20% by weight of MQ resin. In certain embodiments, the adhesive compositions includes less than 10% by weight of MQ resin. In some illustrative embodiments, the adhesive composition is a pressure-sensitive adhesive. In certain illustrative embodiments, the pressure sensitive adhesive is optically clear, self-wetting to the end-use substrate, and stretch releasable. In certain such embodiments, the adhesive article exhibits a 180° PEEL ADHESION to a glass substrate no greater than about 500 N/dm after aging for seven days at 85° C. The pressure sensitive adhesive compositions may be used to form adhesive articles and adhesive assemblies.

  • Patent number: 10160864
    Abstract: Provided are one-part, shelf-stable polyurethane aerosol compositions, and related articles and methods. When sprayed onto a substrate and dried, these compositions provide polyurethane films. These polyurethane films display improved moisture resistance, optical clarity, and weatherability compared to known aerosol compositions, particularly in adverse environmental conditions. The compositions generally include an aqueous polyurethane dispersion containing a urethane moiety obtained by reacting (i) a polyol or thiol having isocyanate-reactive functional groups, (ii) a neutralized water-solubilizing compound, and (iii) a diisocyanate and optionally a silane terminal group; a propellant; and optionally one or more additives.
