  • Patent number: 10040970
    Abstract: A structure based on glass strand coated with a resin composition containing, by weight percent of solid matter: from 75 to 98% of a mixture of a first novolac having a glass transition temperature lower than or equal to 60° C. and a second novolac having a glass transition temperature above 60° C.; from 0.5 to 10% of a wax; from 1 to 15% selected from an imine and a modified melamine of formula (I): where R1, R2, R3, R4, R5, and R6 are each independently —H, —CH2OH, —CH2OCH3, or —CH2OCH2OCH3 radical, with at least one of R1 to R6 not being H; and from 0 to 10% of a plasticizing agent. Also, a resin composition for producing a reinforcing structure and bonded abrasive articles incorporating such a structure.

  • Publication number: 20170029631
    Abstract: The present invention concerns an aqueous flame retardant composition for mineral fiber-based mats, in particular glass or rock fibers, which comprises: at least one thermoplastic or thermoset resin; magnesium hydroxide, Mg(OH)2, and aluminum hydroxide, AlOOH, as flame retarding agents; and optionally, carbon black. It also concerns mats treated with said flame retardant composition.

  • Publication number: 20160122911
    Abstract: A luminous woven fabric comprises a woven textile support comprising warp yarns and weft yarns selected from binding yarns and optical fibers capable of emitting light sideways. The binding yarns comprise glass yarns representing at least 50% by weight relative to the total weight of the binding yarns forming the woven textile support.

  • Publication number: 20130111822
    Abstract: The invention relates to a structure based on glass strand coated with a resin composition which comprises the following constituents in the proportions indicated, expressed in percentage by weight of solid matter: 75 to 98% of a mixture of at least one novolac having a glass transition temperature lower than or equal to 60° C. and at least one novolac having a glass transition temperature above 60° C., 0.5 to 10% of at least one wax, 1 to 15% of at least one crosslinking agent chosen from imines and modified melamines of formula: in which R1, R2, R3, R4, R5 and R6, which are identical or different, represent a hydrogen atom or a —CH2OH, —CH2OCH3 or —CH2OCH2OCH3 radical, at least one of the radicals R1 to R6 being other than H, 0 to 10% of at least one plasticizing agent. The invention also relates to the resin composition suitable for producing the reinforcing structure and bonded abrasive articles incorporating such a structure, in particular abrasive grinding wheels.
