Patent application number | Description | Published |
20090042030 | MINERAL WOOL, INSULATING PRODUCT AND PRODUCTION METHOD - The invention relates to a mineral wool which can dissolve in a physiological medium, comprising fibres having a chemical composition that contains the following constituents in the limits defined hereafter and expressed in percentage by weight, namely: 35 to 75 SiO | 02-12-2009 |
20090054580 | METHOD FOR MAKING A FIBROUS INSULATING PRODUCT, SIZING STUFF AND COMPOSITION - In order to improve the mechanical strength after ageing, particularly in a wet medium, of an insulation product, especially a thermal and/or acoustic insulation product, based on mineral wool provided with a size, a latex is incorporated in the sizing composition which contains especially a phenolic resin. | 02-26-2009 |
20090149624 | Phenolic resin formulation and coatings for abrasive products - A resorcinol-modified phenolic resin composition is formed by reacting a basic catalyst, formaldehyde, water and a benzene-ol to form an intermediate composition to which resorcinol is subsequently added to reduce the presence of free formaldehyde. Optionally, an alkanolamine can be combined and reacted with the resorcinol-modified phenolic resin composition to form a resorcinol-alkanolamine-modified phenolic resin composition. The resorcinol-modified phenolic resin and the resorcinol-alkanolamine-modified phenolic resin compositions can be employed to coat abrasive products having a relatively low free formaldehyde content. | 06-11-2009 |
20090156724 | USE OF GLYCEROL AS ADDITIVE FOR FORMALDEHYDE-FREE AQUEOUS SIZES - The present invention relates to the use of glycerol as additive for formaldehyde-free aqueous sizes based on acrylic or acrylate polymers, which are intended for the manufacture of products based on mineral wool, in order to improve the aging resistance of the products based on mineral wool that are obtained after the size has been crosslinked. The products based on mineral wool bound with such a size, which is environmentally friendly, have the same quality as products conventionally bound with a phenolic resin. The thickness recovery and flexure of the products obtained are improved. | 06-18-2009 |
20090311936 | MINERAL WOOL, INSULATING PRODUCT AND MANUFACTURING PROCESS - One subject of the invention is a process for obtaining mineral wool comprising mineral fibres and an organic binder, in which process said mineral fibres are formed and said organic binder is added on at least part of the surface of said mineral fibres, characterized in that a compound is furthermore added to at least one part of the surface of said mineral fibres, said compound comprising at least one resin acid or resin acid derivative and also a water-repellent agent. The subject of the invention is also a mineral wool that can be obtained by this process. | 12-17-2009 |
20100180512 | GLASS FIBER STRUCTURE DESIGNED TO REINFORCE BONDED ABRASIVE ARTICLES - The invention relates to a structure based on glass fiber coated with a resin composition designed to reinforce bonded abrasive articles, the resin composition being characterized in that it comprises the following constituents in the proportions indicated, expressed in percentage by weight of solid matter:
| 07-22-2010 |
20100252771 | MINERAL FIBRE SIZING COMPOSITION CONTAINING A CARBOXYLIC POLYACID AND A POLYAMINE, PREPARATION METHOD THEREOF AND RESULTING PRODUCTS - The invention relates to a sizing composition intended to be applied to mineral fibers, especially glass or rock fibers, which contains at least one polycarboxylic acid and at least one polyamine. | 10-07-2010 |
20100270495 | LIQUID RESIN COMPOSITION FOR ABRASIVE ARTICLES - The invention relates to a thermally curable liquid resin composition intended for manufacturing abrasives that comprises at least one epoxy resin comprising at least two epoxy groups and at least one reactive diluent, said composition having a viscosity, at 25° C., less than or equal to 7000 mPa.s. | 10-28-2010 |
20100298505 | LIQUID RESIN COMPOSITION FOR ABRASIVE ARTICLES - The invention relates to a liquid resin composition intended for manufacturing abrasives that comprises at least one novolac resin having a glass transition temperature less than or equal to 60° C., at least one reactive diluent and optionally at least one crosslinking agent. | 11-25-2010 |
20130091778 | LIQUID RESIN COMPOSITION FOR ABRASIVE ARTICLES - The invention relates to a thermally curable liquid resin composition intended for manufacturing abrasives that comprises at least one epoxy resin comprising at least two epoxy groups and at least one reactive diluent, said composition having a viscosity, at 25° C., less than or equal to 7000 mPa·s. | 04-18-2013 |
20130338288 | GLASS FIBER STRUCTURE DESIGNED TO REINFORCE BONDED ABRASIVE ARTICLES - The invention relates to a structure based on glass fiber coated with a resin composition designed to reinforce bonded abrasive articles, the resin composition including the following constituents in the proportions indicated, expressed in percentage by weight of solid matter:
