Claims
- 1. A process for the production of a coating composition which is crosslinkable at room temperature, comprising the steps of (i) applying a layer of a coating composition comprising:
- A) one or more resins having amino-reactive groups;
- B) one or more polyamine curing agents;
- C) one or more aminourethanes comprising reaction products of
- C1) oligomeric or polymeric compounds which contain at least one terminal 2-oxo-1,3-dioxolane groups (cyclic carbonate groups), and
- C2) amines containing at least one primary amino group, the ratio of numbers of functional groups in C1) and C2) being from 1:1 to 1:10; and
- D) optionally, pigments, fillers, one or more organic solvents, water and conventional additives
- to a substrate,
- wherein a chemical compound is formed from a reaction between the aminourethane C) and the polyamine curing agent B) prior to the following step (ii) and
- (ii) curing the coating layer, wherein said reaction between said aminourethane C) and said polyamine curing agent B) is selected from the group consisting of
- (a) mixing the aminourethane C) with the polyamine curing agent B), and then reacting this mixture with an emulsifier D);
- (b) reacting the aminourethane C) with an emulsifier D), and then adding the amine curing agent B); and
- (c) reacting the amine curing agent B) with an emulsifier D), and then adding the aminourethane C),
- wherein the emulsifier D) is an adduct of polyepoxides and polyalkylene ether polyols in a ratio of numbers of functional groups of from 2:0.1 to 2:1.5.
- 2. The process as claimed in claim 1, wherein said reaction between said aminourethane C) and said polyamine curing agent B) comprises the steps of:
- 1) mixing said aminourethane C) and said polyamine curing agent B) to produce a mixture, and;
- 2) reacting said mixture with said emulsifier.
- 3. The process as claimed in claim 1, wherein said reaction between said aminourethane C) and said polyamine curing agent B) comprises the steps of:
- 1) reacting said aminourethane C) with said emulsifier to produce a reaction product; and
- 2) mixing said polyamine curing agent with said reaction product.
- 4. The process as claimed in claim 1, wherein said reaction between said aminourethane C) and said polyamine curing agent B) comprises the steps of:
- 1) reacting said polyamine curing agent B) with said emulsifier to produce an amine reaction product; and
- 2) mixing said aminourethane C) with said amine reaction product.
