  • Patent number: 10689476
    Abstract: The present invention relates to a method for producing a cured composition, which has at least one oxazolidinone ring and at least one isocyanurate ring and is crosslinked thereby, starting from a liquid reaction mixture comprising: (a) at least one liquid, aromatic epoxy resin; (b) at least one liquid, aromatic polyisocyanate; and (c) a catalyst composition; relative to the at least one polyisocyanate, the at least one epoxy resin is used in amounts such that the molar equivalent ratio of epoxide groups to isocyanate groups is at least 0.4; and curing the reaction mixture to give a cured polymer composition comprising at least one oxazolidinone ring and at least one isocyanurate ring, and also to the cured compositions obtainable by these methods.

  • Publication number: 20130033773
    Abstract: The invention relates to a reflector (1) for electromagnetic radiation in the wavelength range of 100 nm to 1 mm, having high resistance against weather and corrosion effects, comprising a metal reflector body (2) having a reflecting surface (3), or a reflector body (2) on which a reflective layer (9) is deposited, and a transparent cover layer (4) made of polysiloxane formed in a sol-gel process. In order to maintain the known advantages of sol-gel protective coatings and achieve a technologically more advantageous production method, according to the invention, the cover layer (4) is made of a cross-linked polycondensate product of at least one silicic acid ester and at least one cyclic siloxane oligomer comprising, alkyl, vinyl, and/or aryl groups.

  • Publication number: 20120270023
    Abstract: A composite material including a carrier g of aluminum, an optically effective multi-layer system applied to a side (A) of the carrier. The system having at least 2 dielectric and/or oxidic layers, namely an upper layer and a lower, light-absorbing layer. The lower, light-absorbing layer contains a titanium-aluminum mixed oxide TiAlqOx and/or a titanium-aluminum makes nitride TiAlqNy and/or a titanium-aluminum mixed oxynitride TiAlqOxNy, while the upper layer is an oxidic layer made of titanium, silicon or tin of the chemical composition TiOz, SiOw, or SnOv, where the indices q, v, w, y and z each denote a stoichiometric or nonstoichiometric ratio.
