Promotor D, is a promoter which can be used to increase the reactivity of ketone peroxide/cobalt accelerator based cure systems in a wide variety of unsaturated polyester resins.Promotor D can effectively be used in standard ortho- and iso phthalic acid based polyester resins, Bisphenol A/fumarate resins and vinylester resins. Promotor D can, in vinyl resins, also be used to increase the reactivity of the cure system Trigonox 239/cobalt accelerator and Butanox® LPT/ cobalt accelerator.Promotor D can be used in these resins as a substitute for the promoter Accelerator NL-63-100 (N,N-Dimethylaniline). In comparison with Accelerator-NL-63-100 Promotor D is a low toxic compound.It does not give a yellow to brown discoloration of the cured UP resin part as it is usually observed when aromatic amines are used as promoter.DosingDepending on application area, UP resin used and working conditions, the following promoter dosage level is recommended:Promotor D 0.1 - 2 phr *Cure Characteristics
Promoter for cobalt-accelerated cure systems using ketone peroxides at ambient and elevated temperatures.
