Which Chemical determines set time in acrylics?

Celebrity Q and A's A few months ago I found this incredible article about acrylic nail product chemistry. I don't remember the author's name but they were very thorough and knowledgeable. I'm still not quite sure what part of the chemistry makeup of acrylic products affects its "set" time. What ingredient(s) determine a products traditional/slow or fast/speed set time and how do some products have a faster set time on their pink powder compared to the white? Terry 7/03

The component is BPO that starts the set time and another ingredient that make it go slow or fast and I am sure someone more educated than I can answer that. As far as different colors setting differently the manufacturer can determine that.
