Abstract: A hardcoat composition is described comprising urethane (meth)acrylate oligomer having a first functional groups; an acrylic polymer having second functional groups; wherein the first and second functional groups form a hydrogen bond; and silica nanoparticles. The hardcoat composition may be cured by actinic radiation, upon which the acrylic polymer may be removed by solvent extraction. Also described are articles comprising the cured hardcoat described herein disposed on a surface of a substrate and methods of making an article.

Abstract: The present invention is an optically clear, curable adhesive including a polyvinylbutyral, a polyurethane (meth)acrylate, and a photoinitiator. The polyvinylbutyral has a dynamic viscosity of between about 9 and about 13 mPA·s and a polyvinyl alcohol weight percent of less than about 18%. The polyurethane (meth)acrylate includes the reaction product of a diol, at least one diisocyanate, and a hydroxyfunctional (meth)acrylate or an isocyanatofunctional (meth)acrylate. When the optically clear, curable adhesive is placed between two transparent substrates and made into a laminate, the laminate has a haze of less than about 6%, a transmission of greater than about 88% and an optical clarity of greater than about 98% when cured. The optically clear, curable adhesive also has a peel adhesion of at least about 100 g/cm based on ASTM 3330 when cured.

Abstract: Presently described are components of a spray application system. At least one component comprises a liquid repellent surface layer. The liquid repellent surface (e.g. layer) may comprise a porous layer and a lubricant impregnated into pores of the porous layer; a fluoropolymer; a fluorochemical material and an organic polymeric binder; or a fluorochemical material melt additive and a thermoplastic polymeric material component. The component is typically a liquid reservoir, a liquid reservoir liner, a lid for a liquid reservoir or liner, or a combination thereof. In some embodiments, the component comprises a thermoplastic polymeric material. In some favored embodiments, the component is a removable liquid reservoir or liner. In some favored embodiments, the component is a collapsible liquid reservoir or liner. The spray application system typically further comprises a gravity-fed spray gun. Also described are spray application systems, methods of using a spray application system, as well as methods of making a component of a spray application system wherein the component has a liquid repellent surface.

Abstract: An ionic diol has formula wherein R1 represents an alkyl group having from 6 to 18 carbon atoms; R2 and R3 independently represent alkyl groups having from 1 to 4 carbon atoms; R4 represents an alkylene group having from 2 to 8 carbon atoms; and R5 represents an alkylene group having from 1 to 8 carbon atoms. Antistatic polymers are formed by copolymerization of monomers including a diisocyanate, an ionic diol, a polyether diol, and at least one non-ionic diols. Methods of making the antistatic polyurethanes are also disclosed.
