20090311934 | METHOD FOR PRODUCING A COLOURED MINERAL WOOL PRODUCT COMPRISING THE SAME COLOUR COATING - The invention relates to a method for producing a mineral fibre board which comprises a coloured pigment and whose at least one surface is provided with a non-woven coating made of a substantially black material. The inventive method consists in inserting the coating into a board production device, wherein said coating is embodied in the form of a fabric, which is based on a polyester with appropriate weight per unit square, not precoloured and not impregnated or provided with an additional adhesive agent introduced therein for adhering to fibre pads. A coloured mineral wool product provided with the same colour coating produced by the inventive method is also disclosed. | 12-17-2009 |
20090304919 | FORMALDEHYDE-FREE PHENOLIC RESIN BINDER - The present invention concerns a composition containing: an aqueous dispersion of at least one phenol-formaldehyde resin; at least one amine compound, wherein the molecular mass of the amine compound does not exceed approximately 20 000 g/mole, at least one activated silane, as well as at least one aromatic hydroxyl compound. The composition may be employed as a formaldehyde-free binder for the manufacture of mineral wool. | 12-10-2009 |
20090258776 | COMPOSITIONS FOR MINERAL WOOL - The subject of the invention is a mineral wool, the glass fibres of which have a chemical composition substantially free of boron oxide and comprising the following constituents in the limits defined below, expressed in percentages by weight: 60 to 75 SiO | 10-15-2009 |
