    Abstract: The present disclosure provides an inorganic dental filler including a surface treated with at least one silane. Exemplary silanes described in the present disclosure for the surface treatment of the inorganic filler include silanes of Formula I and/or Formula II: (RSi)—(CR1R2)n—(NH—C(O)—O—CH2—CH2)q—N(R5)—C(O)—NH—(CH2—CH2—O)t—CR3R4—CH2-(A) Formula I (RSi)—(CR1R2)n—NH—C(O)—O—CR3R4-(L)q-CH2-(A) Formula II, wherein: RSi is a silane-containing group of the formula —Si(Yp)(R6)3-p, wherein Y is a hydrolysable group, R6 is a monovalent alkyl or aryl group, and p is 1, 2, or 3. Methods of making and using the surface treated inorganic dental fillers are also disclosed.

    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: The present invention is an optically clear, curable adhesive including a polyvinylbutyral, a polyurethane (meth)acrylate, a (meth)acrylate monomer, 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.
