    Abstract: Chlorhexidine gluconate is a commonly used disinfectant that is soluble in aqueous solutions. Because it is a common disinfectant, chlorhexidine gluconate is often used in alcohol solvents, but chlorhexidine gluconate is not soluble in C 2 -C 5 alcohol solvents. Also, a chlorhexidine gluconate containing solution can be susceptible to spontaneous calcium gluconate crystallization when formulated with high levels of solvent such as alcohol. These calcium gluconate crystals appear like glass shards. It is desirable to inhibit the formation of these crystals without affecting the antimicrobial potency of the solution. The disclosed chlorhexidine antimicrobial composition includes a chelating agent to inhibit formation of this salt or reverse crystal formation.

    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.

    Abstract: Waterborne suspensions include surface treated silica particles, a water dispersable binder resin, at least one surfactant, and an aqueous solvent. The surface treated silica particles have a mixture of hydrophobic and hydrophilic silane surface treatment agents, where the ratio of hydrophilic silane surface treatment agent to hydrophobic silane surface treatment agent is greater than 1. The waterborne suspensions can be coated and dried to form nanostructured tie layers, especially tie layers to silicone or (meth)acrylate layers.
