The present invention relates to a method for producing a cured composition, which has at least one oxazolidinone ring and at least one isocyanurate ring and is crosslinked thereby, starting from a liquid reaction mixture comprising: (a) at least one liquid, aromatic epoxy resin; (b) at least one liquid, aromatic polyisocyanate; and (c) a catalyst composition; relative to the at least one polyisocyanate, the at least one epoxy resin is used in amounts such that the molar equivalent ratio of epoxide groups to isocyanate groups is at least 0.4; and curing the reaction mixture to give a cured polymer composition comprising at least one oxazolidinone ring and at least one isocyanurate ring, and also to the cured compositions obtainable by these methods.

Oxazolidinone- and isocyanurate-crosslinked matrix for fiber-reinforced material

The present invention relates to a one-part curable adhesive composition, in particular, a one-part adhesive composition having excellent initial and aged lap shear strength as well as low viscosity, and to the use thereof.

One-part curable adhesive composition and the use thereof

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.
