20100016475 | IMIDAZOLE SALTS, METHOD FOR PRODUCING THEM, USE THEREOF AND EPOXY RESINS CONTAINING SAID SALTS - The invention refers to salts of at least one imidazole of the general formula (I), in which R | 01-21-2010 |
20100166971 | CATALYST FOR CURING EPOXIDES - The use of 1,3-substituted imidazolium salts of the formula I | 07-01-2010 |
20100179299 | CATALYST FOR CURING EPOXIDES - The use of 1,3-substituted imidazolium salts of the formula I | 07-15-2010 |
20100184925 | CATALYST FOR CURING EPOXIDES - The use of 1,3-substituted imidazolium salts of the formula I | 07-22-2010 |
20100187715 | CATALYST FOR CURING EPOXIDES - The use of 1,3-substituted imidazolium salts of the formula I | 07-29-2010 |
20120259044 | HYPERBRANCHED POLYMERS FOR MODIFYING THE TOUGHNESS OF ANIONICALLY CURED EPOXY RESIN SYSTEMS - The invention relates to a curable composition comprising one or more epoxy compounds, one or more anionically curing catalysts, and an addition of one or more dendritic polymers, selected from the group consisting of the dendritic polyester polymers, the dendritic polyesteramide polymers, and the dendritic polymers based on 1,3,5-tris-alkanol-substituted cyanuric acid. These dendritic polymers improve mechanical properties, in particular the toughness of the cured epoxy resin. | 10-11-2012 |
20130143984 | PRODUCTION OF CURED EPOXY RESINS WITH FLAME-RETARDANT PHOSPHONATES - The invention relates to curable compositions which comprise epoxy resins, amino hardeners, and a phosphonate of the formula I. Addition of phosphonate of the formula I can give cured epoxy resins which have not only improved flame retardants but also an increased glass transition temperature when comparison is made with the corresponding resins without said addition. | 06-06-2013 |
20140243455 | P-PIPERAZINE COMPOUNDS AS FLAME RETARDANTS - The present invention relates to the use of aromatic P-piperazine-compounds in flame retardant polymer compositions. These compositions are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamines or polyesters and duroplastic polymers, such as polyepoxides. | 08-28-2014 |
20140316032 | P-N-COMPOUNDS AS FLAME RETARDANTS - The present invention relates to the use of aromatic P—N-compounds in flame retardant polymer compositions. These compositions are especially useful for the manufacture of flame retardant compositions based onthermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamines or polyesters and duroplastic polymers, such as polyepoxides. | 10-23-2014 |

20140073467 | BELT DRIVE FOR A MOTOR-DRIVEN TOOL - In order to provide a belt drive for a motor-driven tool with a first, drive-side belt pulley, a second, tool-side belt pulley and a belt that can be tensioned over the first and the second belt pulley, that is characterised by being easier to use, it is proposed that a cam, rigidly connected with a shaft, is arranged in the first or second belt pulley, whereby during a rotational movement of the shaft the belt pulley can be moved from an eccentric arrangement in relation to the shaft into a concentric arrangement by way of a translational movement and a rotational movement of the belt pulley. | 03-13-2014 |
20140230211 | POWER CUTTER - A power cutter includes a housing, a first return pulley borne in a rotating manner in the housing and driven directly by a motor arranged in the housing, a cutting arm connected to the housing has a housing in which a second return pulley is arranged in a rotating manner, and is driven by a tension means guided over the first return pulley and the second return pulley, as well as a cutting tool which can be detachably fastened to the cutting arm, and a method of changing the position of a cutting tool of a power cutter, through which handling during changing the position of the cutting tool can be simplified. For the detachable fastening of the cutting tool, the cutting tool is borne on a shaft, whereby the shaft can be detachable fastened to two opposite sides of the second return pulley. | 08-21-2014 |
20140287857 | POWER CUTTER WITH BELT COOLING - A power cutter with an engine and with a cutting arm on which a cutting tool is received and is driven by the engine by way of a belt is provided. The belt may be received in a belt space formed in the cutting arm, and a fan wheel is arranged on the engine so that an air flow for cooling the engine can be generated. A combustion-air flow is provided to the engine, and the fan wheel provides an air circulation system where an air flow at least flows through the belt space and the combustion-air flow branches off from the air circulation system. | 09-25-2014 |
