Abstract:
The present invention relates to a mixture containing at least three hardener components a1), a2), and b), wherein the ratio of the hardener component a1) to a2) is in the range of 0.1-10 to 1, and the hardener component b) is present with 5 to 55 weight percent, relative to the mixture, to a method for producing said mixture, to the use of the mixture according to the invention for hardening epoxy resins, to the use of the mixture according to the invention having epoxy resins as adhesives, and to an epoxy resin hardened with the mixture according to the invention.
Abstract:
The production of epoxy resin compositions comprising glycidyl ether with cyclohexyl groups and having a low oligomer content is achieved by the distillation of compositions, which can be obtained by means of core hydrogenation of compounds of the general formula (I) with -X- -CR2-, -CO-, -O, -S-, -SO2-, R being independently of each other H, C1-6-alkyl, C3-6-cycloalkyl, wherein one or more H can be replaced by halogen, R' independently of each other being C1-4-alkyl, halogen n independently of each other being 0, 1, 2, or 3, and the subsequent reaction of the hydroxyl groups with epichlorhydrine, in thin film evaporators or short-path evaporators at a temperature in the range of 150 to 270°C, and at a pressure in the range of 0.001 to 1 mbar.
Abstract:
The invention relates to the use of 1, 3 substituted imidazolium salts of the formula (I), R1 and R3 independently representing an organic group having 1 to 20 C atoms, R2, R4, and R5 independently representing a H atom or an organic group having 1 to 20 C atoms, R4 and R5 also together being able to form an aliphatic or aromatic ring, and X representing a thiocyanate anion as a latent catalyst for curing compositions comprising epoxy compounds.
Abstract:
The invention relates to fungicidal mixtures that contain A) the compound of formula (I), and B) a pyrimidine derivative of formula (II), wherein R represents methyl, cyclopropyl or 1-propinyl, in a synergistically effective amount. The invention also relates to a method for controlling parasitic fungi using mixtures of the compounds (I) and (II) and the use of compounds (I) and (II) in the production of such mixtures.
Abstract:
2-Propylheptanoic acid glycidyl ester, 4-methyl-2-propylhexanoic acid glycidyl ester or a mixture thereof (referred to in summary as glycidyl esters for short).
Abstract:
The invention relates to curable compounds that comprise epoxy resins, amino hardeners and a phosphonate from formula (I). By adding of phosphonate from formula (I), hardened epoxy resins are obtained according to the invention, which hardened epoxy resins have both an improved fire retardancy and an increased glass transition temperature relative to the corresponding resins without said addition.
Abstract:
The present invention relates to a method for producing molded bodies, wherein a blend is used to harden the mold, said blend containing one or more epoxy resins and a mixture, and the hardening component a) in the range of 0.3 to 0.9 amine equivalent per epoxy equivalent of the epoxy resin used is used in the mixture, and the hardening component b) is a compound of the formula I.
