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

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 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.

1,3-oxathiolane-2-thione compounds

The invention relates to an adhesive containing two components A and B, whereby component A comprises both a functional group which can be polymerized by means of irradiation with UV beams as well as at least one functional group which is able to react with a compound having at least one acidic hydrogen atom and component B comprises at least two functional groups which can be polymerized by means of irradiation with UV beams or with electron beams. The adhesive is suitable for the production of composite materials and exhibits a high flexibility with a good initial bonding.

Polyamides based on reaction products of C-Cdicarboxylic acids and diamines are suitable as molding compositions for the production of moldings in the low pressure injection molding process, and for adhesive sealing or filling in the production of electrical or electronic devices, in particular of plugs, cables, switches, sensors, transponders, modules, printed circuit boards or smart cards. In comparison with conventional molding compositions based in known hot melt adhesives, said polyamides exhibit higher strength values, higher abrasion resistance and higher chemical resistance.

Adhesive systems are useful for bonding wrap-around labels using an overlap adhesive in their application to blown plastic containers, more particularly plastic bottles. The adhesive system includes reactive contact adhesives based on multifunctional macromonomer compounds curable in steps by different reaction mechanisms, which may also be present mixed with one-stage reactive mixture components.

Use of selected adhesive mixtures for overlap adhesion of round labels when applied to plastic bottles

The bondability of a polyolefin, particularly to cyanoacrylate adhesives, is improved by incorporating in the polyolefin a polymerization initiator capable of initiating the polymerization of the monomers constituting the cyanoacrylate adhesive. The polymerization initiator may, for example, be a sterically hindered nitrogen base and may be mixed with the polyolefin at a temperature above the polyolefin's glass transition temperature using, for example, co-extrusion or co-injection methods.
