The use of chemically strengthened glass, which was once only found in low volume specialty applications, is growing as a rapid rate as more and more new applications are found for it. Today, it can be found on the screens of hundreds of millions of smart, phones, tablets, and other devices. The high strength, scratch resistance, light weight and optical clarity also make it an especially attractive material for automotive vehicles where it is just starting to find uses. One of the challenges faced when fabricating an automotive laminate with chemically strengthened glass is in the application of the obscuration needed to hide the mounting adhesive and trim. Conventional black frits are not compatible with the chemical strengthening process. Porous frits, on the contrary, which allow the chemical strengthening to take place, have poor aesthetics. The disclosure provides a process for producing a laminated glazing with at least one chemically strengthened glass layer with a glossy black frit obscuration as well as the laminate itself.

Safety glass and method for its obtainment is presented. The safety glass includes a single glass plate with at least one layer of Polyvinyl butyral (PVB) film applied without adhesive over the interior face of the glass plate and at least one layer of Crystallizable PolyEthylene Terephthalate (C-PET) film applied without adhesive over the at least one PVB film layer on the interior face of the glass plate. The safety film optionally includes a safety film layer for shatter-proofing applied over the exterior face of the single glass plate and/or over the at least one C-PET film layer on interior face of the single glass plate.

Resin layers and interlayers exhibiting enhanced adhesion to inorganic surfaces, such as glass, are provided. In some cases, the layers and interlayers may comprise at least one adhesion stabilizing agent for improving adhesion to various surfaces, even in the presence of moisture. Such layers and interlayers may be useful, for example, in multiple layer panels, such as, for example, safety glass used in automotive and architectural applications.

The present invention relates to drying processes for composite films comprising a polyvinyl acetal on a carrier as well as to composite films and polyvinyl acetal films obtained in such processes.

An optical web comprising includes a substrate with an anterior coating applied to the anterior side of the substrate and a posterior coating applied to the posterior side of the substrate. The refractive index of the anterior coating and the posterior coating is less than that of the substrate. A second coating layer may be applied to the anterior coating layer and/or the posterior coating layer, where the second coating layer has a refractive index less than that of the coating layer it is applied to. Additional coating layers may be applied to produce a stack of layers that decrease monotonically in refractive indexes moving outward from the substrate. The optical webs may be laminated together to form tear-off laminated lens stacks.

The present invention concerns a glazing for electric heating, comprising a first glass sheet, a first masking layer around the periphery of the first glass sheet, an aperture in the first masking layer for a sensor, a second glass sheet bonded to the first glass sheet by a ply of interlayer material, a carrier film positioned between the ply of interlayer material and the first glass sheet, an electric heating element on the carrier film, and a second masking layer on the carrier film. The second masking layer positioned on a carrier film causes less stress in the glass sheets during moulding and thus less optical distortion. The invention also concerns a method of manufacturing the glazing and use of the glazing for example as a window for a vehicle.

Due to the increased glazed area of modern vehicles, especially the large panoramic glass roofs, we have seen a substantial growth in the use of anti-reflective coatings. Unfortunately, these types of coatings accentuate fingerprints and smudges. The invention provides an automotive glazing which is substantially resistant to fingerprints, and a method of manufacture thereof through the application of an anti-fingerprint coating based on low surface energy silanes.

A wafer-like semiconductor sensor includes a wafer-like base formed of a plurality of layers of chemically-hardened glass and an electronics module mounted to a recessed pocket in the base and containing a sensor.

An ionomer-based adhesive polymeric interlayer (API) that provides enhanced properties to rigid substrates through the use of polyvinyl acetal-based controlled debonding zone treatments, and rigid substrate-laminates comprising such interlayers.

The present invention relates to an eco-friendly panel and a manufacturing method therefor. Specifically, the eco-friendly panel includes: a waste fiber felt layer molded from at least one selected from the group consisting of polyester, cotton, and other fibers that are classified as waste fibers and cut into predetermined sizes; at least one mucous layer in which at least one powder selected from the group consisting of zeolite powder, bentonite, montmorillonite, briquette ash, volcanic soil, perlite, ocher, charcoal, orthoclase powder, elvan powder, jade powder, germanium powder, and calcined shell powder is stirred in mixture with a mucilage substance extracted from waste algae such as waste brown algae, waste red algae, or waste green algae; and at least one nanocarbon layer in which plate-shaped graphite, graphene, and boron nitride are mixed at a weight ratio of 2:1:0.5, wherein copies of the waste fiber felt layer, the mucous layer, and the nanocarbon layers are sequentially or non-sequentially stacked and hardened through heat compression and cold compression.
