A latent curing agent obtained by the reaction of a coumarin compound of the general formula (1), where X and Y can be independently H, an alkyl group, a heteroalkyl group, an aromatic group, a heteroaromatic group or an acetyl group and Z can be H, OH, an alkyl group, a heteroalkyl group, an aromatic group, a heteroaromatic group with an amine of the general formula (2), 

Latent curing agent and epoxy compositions containing the same

The present invention relates to a curable composition, comprising at least one benzoxazine compound, and at least one sulfonic acid ester having a cyclic structure. In particular, the invention relates to the use of at least one sulfonic acid having a cyclic structure as a heat-activatable catalyst for curable composition, comprising at least one benzoxazine compound.

Curable compositions

A method for production of an N-carboxy amino acid anhydride with efficiency is provided. The method for production of an N-carboxy amino acid anhydride includes a step of reaction of an amino acid organic salt compound with a carbonic acid diester.

Method for production of N-carboxy amino acid anhydride and amino acid carbamate compound

The present invention relates to a catalyst, which is an organic component with electron withdrawing substituents and to compositions with such catalyst and at least one benzoxazine component, and the use of such compositions in adhesives, sealants and coatings.

Benzoxazine-containing formulations polymerizable/curable at low temperature

Polymerizable combinations, comprising at least one first component selected from the group of benzoxazine monomers and at least one second component selected from the group of aromatic esters are described. Further on the use of aromatic esters as additives to benzoxazine monomers as well as methods of coating a device by heating the above mentioned combination, and a device, coated by that way is explained.

Benzoxazine-formulations with reduced outgassing behaviour

The present invention provides a process for producing an amino acid N-carboxyanhydride, which comprises reacting an amino acid or a derivative thereof with a compound represented by the following formula (1): wherein Rand Rrepresent the same or different electron-withdrawing substituents and each independently are an optionally substituted acyl group, an optionally substituted alkyloxycarbonyl group, an optionally substituted perfluoroalkyl group, an optionally substituted perchloroalkyl group, a cyano group, a halogen atom, or a nitro group; and a and b are the same or different and each are an integer of 1-5.

Process for producing amino acid N-carboxyanhydride

The present invention relates to adhesion-improved, curable compositions comprising a cyclic ether, a cyclic thiocarbonate, an amine and a carboxylic acid. A method of making such compositions and their use in adhesives, sealants and coatings are also provided.

Curable compositions having improved adhesion performance

The present invention relates to compositions comprising an epoxy resin; a reagent selected from the group of cationic compounds or compounds which are capable to form cationic compounds or mixtures of those; at least one compound with two aromatic rings and at least one central cyclic oxygen bridged ring and the use of such compositions in adhesives, sealants and coatings.

Low shrinkage epoxy-cationic curable compositions

The present invention relates to 1,3-oxathiolane-2-thione compounds of the general formula (I): wherein Rand Rare the same or different, each of which denotes a straight-chain or branched alkoxy residue with 1 to 6 carbon atoms or an aryloxy or aralkyloxy residue, Ris different or the same as Ror Ror an aliphatic residue, an amino residue, a halogen residue, an aromatic or heteroaromatic residue, or an araliphatic or heteroaraliphatic residue, Ris a bridging group selected from the groups consisting of aliphatic, heteroaliphatic, araliphatic, heteroaraliphatic, aromatic and heteroaromatic groups and Ris hydrogen, an aliphatic, heteroaliphatic, araliphatic, heteroaraliphatic, aromatic, heteroaromatic, cycloaliphatic or heterocycloaliphatic group or Rand Rform a cycloaliphatic, cycloheteroaliphatic, aromatic or heteroaromatic residue, which is optionally substituted with an aliphatic, heteroaliphatic residue serving as a bridging group to the silicon atom and X and Y are different and selected from oxygen and sulfur and mixtures of such compounds.
