Abstract
The invention relates to a thermosetting reactive resin mixture of a) at least one organic compound, which possesses at least two epoxide groups, b) at least one carbamate compound of the formulae I, II, III or IV, such as can be quoted from the claim petitions, c) at least one basic catalyst, and with or without d) other processing aids and/or additives. The thermosetting reactive resin mixture according to the present invention are used for chemically resistant coatings, as cross-linked, no longer soluble and infusible moulded articles, for the production of cathodically precipitable electrophoretic enamels, and for the production of coating powders and automobile paints.
Claims23
A thermosetting reactive resin mixture comprising
- (a) at least one organic compound, which possesses at least two epoxide groups,
- (b) at least one carbamate compound of the general formula I, ##STR10## wherein R.sup.1, R.sup.2 mean a hydrogen atom or a methyl group,
- R.sup.3 means a hydrogen atom, a methyl group or a di- or trivalent aliphatic, cycloaliphatic, aromatic or heterocyclic residue with at most 20 carbon atoms,
- n means 1, 2 or 3,
- and said at least two epoxide groups of the organic compound react with the urethane group of formula I,
- (c) at least one basic catalyst, and with or without
- (d) other processing aids and/or additives.

- R.sup.4 means a hydrogen atom, a mono-, di-, tri- or tetravalent aliphatic, cycloaliphatic, aromatic or heterocyclic residue with at most 20 carbon atoms,
- p means 0 or 1,
- z means 0 or 1, provided that p is greater than or equal to z,
- m means 1, 2, 3 or 4,
- and said at least two epoxide groups of the organic compound react with the urethane group of formula II,
- (c) at least one basic catalyst, and with or without
- (d) other processing aids and/or additives.
