Trigonox® 61 is an organic peroxide mixture with methyl ethyl ketone peroxide and acetylacetone peroxide for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures. With the curing system Trigonox® 61/cobalt accelerator a faster speed of cure can be obtained than with Butanox M-50; however, the high cure rates achieved with Trigonox® 44B are not attainable. The gel times with Trigonox® 61 are in general similar to those with Butanox M-50. The curing system Trigonox® 61/cobalt accelerator is particularly suitable for the curing of gelcoat resins, laminating resins and for applications where a shorter demoulding time than obtained with Butanox M-50 is required. Moreover the manufacture of light resistant parts may be possible contrary to the curing system benzoyl peroxide/amine accelerator.
