Tno, Huntsman Advanced Materials GmbH and Philips | Date: 2012-04-25

An opto-electric device is presented that comprises an opto-electric element (10) enclosed by a barrier structure (20) for inhibiting a transmission of moisture from an environment towards the opto-electric element. The barrier structure includes a stack of layers comprising at least an inorganic layer (22) and a moisture getter material in a layer arranged between the inorganic layer and the opto-electric element. The stack includes a lateral diffusion layer (26), wherein the getter material is present in a separate getter layer (24) arranged between the opto-electric element (10) and the lateral diffusion layer (26) and/or the getter material is present in the lateral diffusion layer (26).


Patent
Tno, Philips and Huntsman Advanced Materials GmbH | Date: 2012-04-25

An organic opto-electric device is disclosed comprising an opto-electric element (10) and a protective enclosure (20) for protecting the opto-electric element (10) against atmospheric substances. The protective enclosure comprises a multi-layered protective layer (30) in which a first inorganic layer (32), a first organic layer (34) comprising a getter, a second organic layer (36) free from getter material and a second inorganic layer (38) are stacked in the order named, wherein the first and the second inorganic layer encapsulate the first and the second organic layer. The getter is distributed in the first organic layer (34) as nanometer sized particles and the second organic layer (36) has a thickness of at least 10 m.

Polymer based manufactured components for construction applications have been designed, developed and demonstrated in European projects such as HP FUTURE-Bridge, SAFEFLOOR and MEGAWIND. The results are very promising regarding customer requirements, quality, technical and economical feasibility and the favourable impact of using this kind of composite-based components in terms of sustainability, safety and quality of life. However, there is a need to industrialise the whole construction process of the Fibre Reinforced Polymers (FRP) components in order to really achieve these results. Further integration of the entire supply and value chain is needed, as well as the development of a high technology for design and manufacturing of FRP components, to transform on-site construction to off-site manufacturing. The overall objective of the Trans-IND project is to develop a cost-effective integrated construction process that will enable the maximum capability of industrialisation of components for transport infrastructures (road and pedestrian bridges, underpass, containing walls, acoustic and safety barriers) using polymer based materials (carbon fibre, glass fibre ). It will be demonstrated, as a pilot case, for components of a bridge (beams and preslabs) due to a higher complexity in the bridge components manufacturing and assembly compared to other applications.


The invention provides a fabric comprising one or more polyesters optionally with other fibers which is treated with a finish comprising at least one fluorochemical stain repellent agent and at least one fluorochemical stain release agent, wherein the fabric maintains oil repellency and stain release capability after at least five industrial launderings at about 55 0C to about 65<0>C. The invention also provides a method of treating a fabric with a finish to impart oil repellency, water repellency, and stain release which is durable to repeated industrial laundering. The invention further provides textile articles comprising the treated fabric, and a method for industrial laundering of such treated fabric and textile articles.

Patent
Huntsman Advanced Materials GmbH | Date: 2012-07-11

A method of making a seamless model free of bond lines. The method includes the sequential steps of providing a substructure having an exposed outer surface, applying a modelling paste to a structure support in the form of a continuous layer, curing the applied modelling paste, and machining the cured layer of modelling paste to the desired contour. The modelling paste is a low density curable composition prepared from thixotropic epoxy or polyurethane containing microballoons.
