<p>A curable casting composition based on epoxide resins shows an unexpectedly high curing rate when the casting composition contains (i) an epoxide group with at least one aminoglycidyl group in the molecule, (ii) a curing agent and (iii) a fluorine containing surfactant (FCS). A curable casting composition based on epoxide resins shows an unexpectedly high curing rate when the casting composition contains: (i) an epoxide group with at least one aminoglycidyl group in the molecule, (ii) a curing agent and (iii) a fluorine containing surfactant (FCS) of formula (I) in which the hydrophobic residue has the formula (Ia). R-(C(R)(R1)-C(R)(R1))x-A (I) R-(C(R)(R1)-C(R)(R1))x- (Ia) A = the hydrophobic part of the surfactant; R and R1 = H or F; and x = 2-12, preferably 3-5. Independent claims are also included for the following: (1) coatings, adhesives, fiber reinforced plastics, structural parts and electrical insulation obtained from the composition; (2) a process for preparation of the composition by mixing the components and additives in any order, preferably by premixing component (iii) with components (i) or (ii) to give the finished composition.</p> |
