Abstract: Biocidal roofing granules are prepared by providing a mineral core and at least one biocidal photocatalytic metal oxide. A gel-forming inorganic coating medium is prepared and used to coat the mineral core to form a coating layer having a porous network on the mineral core, and the at least one biocidal photocatalytic metal oxide is disposed in the porous network.

Abstract: The invention relates to biocidal granules composed of a mineral core coated with at least one porous inorganic layer including at least one organic compound capable of limiting or preventing the growth of microorganisms, in particular of algae. The invention also relates to a sol-gel process for the preparation of the biocidal granules and to the use of these biocidal granules in building materials, in particular shingles and siding coatings.

Abstract: The invention relates to a substrate comprising at least one photocatalytic compound active under the conditions of illuminating an interior of a building or transport vehicle, intended to neutralize the microorganisms with which it comes into contact, and also to its preparation processes and its uses as glazing or another substrate for disinfection, filtration, ventilation, etc.

Abstract: A method of coating an optical fiber includes a step of coating the fiber with a curable coating composition and a step of curing the composition, which contains an unsaturated compound having a double bond and an oxidation catalyst. The curing step includes an in-line first phase consisting in exposing the coated fiber to UV radiation for a time shorter than the time needed for complete curing followed by an off-line second phase consisting in placing the coated fiber in an oxidizing medium in order to complete curing.

Abstract: In a thin conductor cable configured as a flat ribbon cable and surrounded by a common exterior sheath, the plurality of thin conductors are adhesively grouped together using an emulsion polymer.

Abstract: Method of production of a coating composition useful for covering glass fiber by means of a polymeric composition consisting of an aqueous suspension or emulsion of a polymer. The coating composition is deposited on the glass fiber and, next, the assembly is submitted to a curing process that is carried out at very high temperature and during a very short period of time.

Abstract: Coating for an optical fiber and method of manufacturing thereof, the coating comprising at least one partly crosslinked polymer having a level of crosslinking which increases according to a radial distance as one moves from the internal surface (3) of the coating (4) which interfaces with a cladding section (2) to the external surface of the coating (4). The coating comprises a single resin which is composed of a volatile, multifunctional and moderately reactive monomer dissolved in a fast curable oligomer, having a low modulus when polymerized.

Abstract: The filamentary elements are of a diameter that is less than or equal to 1 millimeter. The support comprises longitudinal channels each intended to house a respective filamentary element, each channel being defined by two longitudinal walls interconnected by a web and defining a longitudinal channel opening, the width of said longitudinal opening being variable by elastically deforming the longitudinal walls between an access configuration giving access to the channel enabling a filamentary element to pass through said opening and a retaining configuration for retaining a filamentary element in the channel. The filamentary elements are selected from optical fibers and electrical coaxial cables.
