Abstract: Pressure sensitive adhesives and tapes having flame-retardant properties include a substrate layer and a layer of pressure sensitive adhesive disposed on the substrate layer. The pressure sensitive adhesive is a UV-cured composition of a curable composition. The curable composition includes a polymerizable (meth)acrylate-based mixture, a polymerizable aromatic (meth)acrylate oligomer, a liquid flame retarding agent, and at least one UV initiator. The UV-cured composition is an optically clear pressure sensitive adhesive with flame retarding properties.

Abstract: Structured surfaces are described. In one embodiment, the structured surface comprises a plurality of structures having complement cumulative slope magnitude distribution (Fcc) such that at least 30, 40, 50, 60, 70, 80 or 90% of structures have a slope greater than 10 degrees; and less than 80% of the structures have a slope greater than 35 degrees. In other embodiments, the structures comprise peaks and valleys defined by a Cartesian coordinate system such that the peaks and valleys have a width and length in the x-y plane and a height in the z-direction and at least a portion of the peaks and/or valleys vary in height in the y direction and/or the x-direction by at least 10% of the average height. Articles and methods are also described.

Abstract: An adherable film includes a substrate that is substantially free of a flame retardant material and has a top major surface and a bottom major surface. An adhesive layer disposed on the bottom major surface of the substrate has a continuous pattern. The adhesive layer is made of an adhesive that is substantially free of a flame retardant material. In a plan view, the continuous pattern defines a plurality of discontinuous non-adhesive portions of the substrate without the adhesive. Each discontinuous non-adhesive portion is completely surrounded by the continuous pattern. The adherable film including the adhesive layer having the continuous pattern exhibits an improved flame retarding characteristic relative to a discontinuous adherable film having a substrate with a same material composition as that of the substrate of the adherable film and a discontinuous adhesive layer with a same material composition as that of the adhesive layer of the adherable film.

Abstract: Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

Abstract: The present disclosure provides a radiative cooling article including a white diffusely reflective microporous layer and a non-white color reflective mirror film having first and second optical layers. The white diffusely reflective microporous layer has a solar weighted reflectivity at normal incidence of electromagnetic radiation over a majority of wavelengths in a range of 350 nanometers (nm) to 2500 nm of 0.8 or greater, 0.85, 0.9, or 0.95 or greater. The non-white color reflective film is disposed adjacent to a major surface of the white diffusely reflective microporous layer and the non-white color reflective film reflects a wavelength bandwidth of at least 30 nm within a wavelength range of 350 nm to 700 nm. The non-white color reflective film can be tuned to reflect light of a specific color (e.g., blue light, green light, or red light). The radiative cooling article may be useful for applications including commercial graphics located outdoors (e.g., on vehicles or buildings). The present disclosure further provides a composite cooling article including the radiative cooling article attached to a vehicle or a trailer. Also, the present disclosure provides a multi-surface passive cooling article including first and second elements in which at least one of the elements includes the radiative cooling article.

Abstract: Methods and kits including writable and cleanable articles, wherein in one embodiment, a method of replenishing a hydrophilic surface on a writable and cleanable article is provided. The method comprising: providing a writable and cleanable article that includes a hydrophilic overcoat that has an at least partially depleted (i.e., at least partially exhausted) hydrophilic surface; and applying a cleaning and protecting composition to at least a portion of the hydrophilic overcoat; and drying the cleaning and protecting composition to provide a dried surface having a replenished hydrophilic surface. The writable and cleanable article includes: a base member having a front surface; a facing layer comprising a cured polymeric matrix and a plurality of inorganic nanoparticles dispersed in the polymeric matrix, wherein the facing layer is disposed on at least a portion of the base member front surface; an optional primer layer disposed on at least a portion of the facing layer; and a hydrophilic overcoat bonded to the facing layer and/or the optional primer layer through siloxane bonds, thereby providing a hydrophilic surface that is writable and cleanable. The cleaning and protecting composition includes: a hydrophilic silane; a surfactant; and water.
