The present invention relates to heat-curable reaction resin mixtures comprising at least one organic polyisocyanate, at least one organic compounds having epoxy rings, and mixtures of certain tertiary amines as reaction accelerators. These reaction resin mixtures are suitable as casting resins for mold making and for the production of various kinds of composites. The curing of the resins takes place in economically reasonable time periods, without excessive evolution of heat, while avoiding shrinkage and the formation of cracks and bubbles.

Heat-curable reaction resin mixtures and the use thereof

The invention relates to a method and a device for producing a solid-forming or foam-forming flowable reaction mixture by metered injection of flowable reaction components into a mixing zone from which the finished reaction mixture is discharged.

Device for producing a solid-forming or foaming flowable reaction mixture

The present invention relates to a method and a device for producing shaped articles from a multi-component reaction mixture which forms, for example, polyurethane, epoxy resin, polyester resin or polyamide, by mixing at least two of the individual components in at least two premixing chambers to form multi-component reaction mixture and these mixtures are subsequently mixed in a single-stage mixing chamber to form a mixture which is introduced into a shaping zone in which it is cured to form the shaped article.
