Problems solved by technology
[0005] Aliphatic amines, such as ethylenediamine, diethylenetriamine, and triethylenetetramine, or araliphatic amines, such as m-xylylenediamine, have disadvantages in spite of their higher reactivity, such as, Especially with high vapor pressure or high yellowing tendency

[0037] Recipe Components
[0038] With the reactive diamine C64 diamine and BAMCO, an epoxy system is obtained that is not brittle and cures well at room temperature.
[0039] Recipe Components
[0040] The use of C64 diamine and BAMCO, in combination with other amines, such as IPD, enables very reactive, non-tacky formulations with good performance.
[0041] Recipe Components
[0042] With this C64 diamine and BAMCO-epoxide system, the same excellent heat distortion resistance as in the case of cycloaliphatic diamines can be achieved, but the acetone resistance is improved.

Description
technical field [0001] The present invention relates to curable compositions based on epoxy resins and 3(4)-(aminomethyl)cyclohexane-propylamine and 1,4(5)-cyclooctanedimethylamine. Background technique [0002] Epoxy resins are prepolymers containing 2 or more epoxy groups per molecule. These resins react with a variety of curing agents to form crosslinked polymers. A review of the resins and curing agents and their use in terms of performance is given in H. Schuhmann, Handbook of Concrete Protection by Coatings, Expert Press 1992, pp. 396-428. [0003] It is known that for curing epoxy resins, such as those based on bisphenol A diglycidyl ether, cycloaliphatic diamines can be used, in addition to various other amine curing agents, such as Isophore ketone diamine (IPD). However, their relatively low reactivity compared to aliphatic amines is a disadvantage in applications. [0004] Cycloaliphatic amines usually cure only incompletely at room temperature. In order to ob...
