Infrared reflectors are described. In particular, infrared reflectors with reduced off-axis color are described. Such infrared reflectors may be useful in laminated glass constructions, particularly for applications where the glass may be exposed to water.

High efficiency infrared reflector having reduced color

Articles and laminates include a substrate with a first polyester surface and a second polyester surface, a crosslinked polyurethane-based primer coated on at least the first polyester surface, and an optically clear heat activated adhesive adjacent to the crosslinked polyurethane-based primer. The articles and laminates are prepared by applying a polyurethane-based dispersion and a crosslinker on at least one polyester surface, drying the applied coating, heating while stretching the substrate and the coating to form a crosslinked primer layer on the stretched polyester surface, and applying an optically clear heat activated adhesive onto the crosslinked primer layer.

Primer compositions for optical films

The present disclosure relates to dyed polyester films whose color remains stable after prolonged exposure to UV radiation and to methods of making such dyed polyester films.

Durable extruded dyed polyester films

A roofing shingle may include a substrate, granules and multilayer infrared light reflecting film particles. In some cases, a roofing shingle may include a substrate, granules and a multilayer infrared light reflecting film disposed either above or below the granules. Such roofing shingles may exhibit improved solar reflectivity. An infrared light reflecting mixture may include inorganic granules and polymeric multilayer infrared light reflecting film particles. An existing construction surface may be treated to improve its solar reflectivity.

Energy efficient construction materials

An article for securing a window film to a window frame includes an elongate body having a first end and a second end, a first portion having a first attachment surface extending from the first end to the second end, a connecting portion extending outwardly from the first portion opposite the first attachment surface, and a second portion joined with the end of the connecting portion opposite the first portion. Methods of anchoring an applied window film to a window frame using the article are also disclosed.

Window film attachment article

A durable optical film or element includes a polymerized structure having a microstructured surface and a plurality of surface modified colloidal nanoparticles of silica, zirconia, or mixtures thereof. Display devices including the durable microstructured film are also described.

Durable optical element

A tear resistant solar control multilayer film article is disclosed. The multilayer film article includes an infrared light reflecting multilayer film having alternating polymeric layers of a first polymer type and a second polymer type and the alternating polymeric layers cooperate to reflect infrared light; an infrared light absorbing nanoparticle layer including a plurality of metal oxide nanoparticles dispersed in a cured polymeric binder, the infrared light absorbing nanoparticle layer being adjacent the infrared light reflecting multilayer film, and a tear resistant polymeric film disposed adjacent to the infrared light reflecting multilayer film.

Tear resistant solar control multilayer film

A durable optical film includes a polymerized optical film structure having a microstructured surface and a scratch contrast ratio value in a range of 1.0 to 1.65 or 1.0 to 1.15. These durable optical films can include a plurality of nanoparticles and a rounded prism apexes microstructure.

Disclosed are various fluoropolymer blend combinations and multilayer articles comprising a blend in a first layer and a second layer comprising a polymer bonded to the first layer. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, and a second layer bonded to the first layer, the second layer comprising a partially-fluorinated thermoplastic polymer, a perfluorinated thermoplastic polymer, or a combination thereof. The invention also provides an article comprising a first layer comprising a blend of two or more fluoropolymers, at least one of which comprises a partially-fluorinated thermoplastic polymer, and optionally at least one perhalogenated polymer, and a second layer bonded to the first layer, the second layer comprising an at least partially-fluorinated thermoplastic polymer. The invention also provides processes for preparing blended fluoropolymers and multilayer articles comprising a fluoropolymer layer.

Fluoropolymer blends and multilayer articles

A multi-layer structure includes a fluoropolymer bonded to a substrate. The structure is prepared by heating a bonding composition to form the bond. The bonding composition includes an amino-substituted organosilane. The bonding composition includes non-adhesive materials.
