Claim:
A curable casting compound comprising an epoxy resin, a curative, and optional additives, wherein the casting compound comprises at least (i) an epoxy resin which contains at least one aminoglycidyl group in the molecule, (ii) a conventional curative or a mixture of such curatives, and (iii) a fluorosurfactant of the following formula (1): R—[C(R)(R 1 )—C(R)(R 1 )] x -A (I) in which: the radical of the following formula (Ia): R—[C(R)(R 1 )—C(R)(R 1 )] x —(Ia) is a hydrophobic radical; R and R 1 independently of one another denote hydrogen or fluorine; and x denotes an integer of 2-12; the substituent A of the formula (I) corresponds to the following formula (Ib): —[C(R 2 )(R 3 )—C(R 2 R 3 )O] y —B (Ib) in which: R 2 and R 3 independently of one another denote hydrogen or fluorine; y denotes zero or an integer from 1 to 10; B denotes at least one of hydrogen, an anionic radical, a cationic radical, and an amphoteric radical; wherein if B is hydrogen, y denotes an integer from 1 to 10.
