Abstract: The present invention relates to a mat of polymer fibers capable of trapping formaldehyde which contains at least 0.5% by weight of an acetoacetamide of formula: in which R1 and R2, which may be identical or different, represent a hydrogen atom, a methyl radical or an ethyl radical. Another subject of the invention is the use of said mat, in particular as a surface covering for thermal and/or sound insulation products, in particular based on mineral wool, polystyrene or on an organic or inorganic foam.

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.

Abstract: The present invention relates to a mat of polymer fibers capable of trapping formaldehyde which contains at least one dihydrazide. Another subject of the invention is the use of said mat, in particular as a surface covering for thermal and/or sound insulation products, in particular based on mineral wool, polystyrene or on an organic or inorganic foam.

Abstract: The present invention relates to a film-forming composition intended to be applied to an inner surface of a building which includes an agent capable of trapping formaldehyde chosen from compounds comprising active methylene(s), tannins and amides. Another subject matter of the present invention is the use of said film-forming composition in reducing the amount of formaldehyde in the air inside a building.

Abstract: The present invention relates to a mat of mineral fibers which comprises an agent capable of trapping formaldehyde present in particular in dwellings or offices and transportation vehicles. The agent capable of trapping formaldehyde is chosen from compounds comprising active methylene(s), hydrazides, tannins, amides, amino acids and sulfites. Another subject matter of the present invention is the processes for the manufacture of said mat of mineral fibers.

Abstract: The present invention relates to a painter's canvas based on glass fibers intended to be applied to an interior surface of a building, which includes an agent capable of trapping formaldehyde chosen from compounds comprising active methylene(s), hydrazides, tannins, amides, amino acids, peptides and proteins. Another subject matter of the present invention is the process for producing said painter's canvas.

Abstract: An abrasive product comprises an abrasive component and a bond component. In one embodiment, the bond component includes a binder and a filler component that includes a cryolite and at least one member selected from the group consisting of sodium oxalate (Na2C2O4), sodium borate (Na2B4O7.10H2O), sodium polyphosphate (NaPO3), opal glass, a hexafluorophosphate, a hexafluoroferrate, a hexafluorozirconate and ammonium tetrafluoroborate. In another embodiment, the bond component includes a binder and a filler component that includes at least one member selected from the group consisting of a hexafluoroferrate, a hexafluorophosphate and a hexafluorozirconate. Alternatively, an abrasive product comprises an abrasive component and a filler component that includes at least one member selected from the group a hexafluoroferrate and a hexafluorozirconate. The abrasive component includes at least one of abrasive particles and agglomerates of abrasive particles.

Abstract: The invention relates to a monolithic polymer material comprising alternating copolymers formed by a radical reaction between a maleic anhydride in the form of a base monomer and ethylene comonomers in the form of electron donors. The invention also relates to a method for preparing said monolithic material consisting in carrying out a radical polymerization reaction of a composition which comprises a base composition containing a maleic anhydride in the form of a base monomer associated with the ethylene comonomers in the form of electron donors and/or with other ethylene comonomers in the form of electron donors or receivers and a mixture of pore-forming solvents, wherein said base composition is optionally supplemented with a thermal initiator or photo initiator.
