  • Patent number: 10385244
    Abstract: The present invention comprises a single-component binder for heat-sealing applications which can be used for the sealing of polyester foils, in particular of polyethylene terephthalate foils (PET foils) with respect to containers made of polystyrene, of PVC, and of polyester. These polyesters can in particular be polyethylene terephthalate (PET) or polylactic acid (PLA). The binders here feature not only good seal seam strengths but also in particular good transparency and excellent application properties. A substantive aspect of the invention is that the sealing can be achieved without addition of adhesion promoters, in particular without addition of adhesion promoters based on polyvinyl chloride (PVC) or on polyester, and that barrier properties and sealing properties achieved in respect of containers made of PS and of PET are nevertheless at least comparable with, and sometimes better than, those achieved with heat-sealing systems already marketed.

  • Patent number: 10071510
    Abstract: The invention relates to a process for producing storage-stable polyurethane prepregs and to moldings (composite components) produced therefrom. The prepregs and, respectively, components are produced by mixing (meth)acrylate monomers, (meth)acrylate polymers, hydroxy-functionalized (meth)acrylate monomers and/or hydroxy-functionalized (meth)acrylate polymers with uretdione materials. Photoinitiators can also optionally be added. This mixture or solution is applied by known processes to fiber material, e.g. carbon fibers, glass fibers or polymer fibers, and is polymerized with the aid of radiation or of plasma methods. Polymerization, e.g. at room temperature or at up to 80° C., gives thermoplastics or thermoplastic prepregs, and these can subsequently also be subjected to forming processes. The hydroxy-functionalized (meth)acrylate constituents can then be crosslinked with the uretdiones already present within the system, by use of elevated temperature.

The reactive or highly reactive polymer composition contains a (meth)acrylate-based resin comprising at least one of a hydroxyl group, an amine group, a thiol group, an initiator and/or accelerator, and a di- or polyisocyanate which has been internally capped, capped with a capping agent, or a combination thereof. The (meth)acrylate-based resin contains from 20% by weight to 70% by weight of at least one (meth)acrylate monomer and from 1% by weight to 50% by weight of at least one prepolymer.

  • Patent number: 9701846
    Abstract: A radiation-reflecting road marking, comprising: metal particles having a diameter of between 0.5-2.5 mm, wherein the metal particles are particles comprising aluminum, magnesium, zinc or an alloy thereof. Also, a method for producing the radiation-reflecting road marking, where the radiation-reflecting road marking is a cold plastic, by mixing components of a two-part system, if necessary, to form a mixture, applying the mixture to a road surface, and adding the metal particles and optionally glass beads during or directly after an application of the cold plastic to the road surface.

  • Patent number: 9433969
    Abstract: A 3D extrusion print process for producing multicolored three-dimensional objects is provided. The process produces mechanically stable, multicolored 3D objects with good color definition. The process according to the invention is based on coating, upstream of the printing head, of the polymer strand used for producing the actual object, and on fixing of the coating upstream of entry of the polymer strand into the printing head. Downstream of the extrusion process in the printing head, the coating remains predominantly at the surface of the extruded strand.

  • Publication number: 20160017151
    Abstract: The present invention encompasses an innovative concept for the marking of trafficways, more particularly roads. The application qualities and lifetime of these new markings are comparable with those of the prior art. The markings also possess properties comparable with those of the prior art in respect of night visibility, back-in-service time, and surface quality. An additional contribution of the markings of the present invention, however, is that they can be used to support modern driver assistance systems and autonomous driving. With this in mind, the present invention relates more particularly to road markings which, building on established systems, are equipped with additional reflection capacity for electromagnetic radiation, more particular for microwaves and/or infrared radiation.
