Applications
Promotor C, acetylacetone or 2,4-pentanedione, is a promoter for ketone peroxide/cobalt accelerator based cure systems for the ambient and elevated temperature cure of unsaturated polyester resins.Promotor C when used in combination with e.g. Butanox M-50/ Accelerator NL-49P will shorten the gel time and will increase the cure speed, which results in a shorter demoulding time.Promotor C can in this respect be used as an alternative for aromatic amines like Accelerator NL-63-10P. Promotor C will not give a yellow discoloration of the endproduct as observed with the use of an amine accelerator. Promotor C can very effectively be used at elevated temperatures to increase the reactivity of perester/cobalt accelerator based cure systems like Trigonox 21, Trigonox 42 or Trigonox C in combination with Accelerator NL-49P (1% Cobalt) or Accelerator NL-51P (6% Cobalt).
