An epoxy-polymercaptan reaction that is catalyzed with a tertiary amine is used in the standard two-component 5-min curing epoxy which can be found in the hardware stores. These fast-curing products, however, have a tendency to be somewhat brittle and may perform quite poorly under peel stress. The standard 5-min cure is obtained with the accelerated mercaptan, such as Capcure 3830-81 (Cognis Corporation). The fastest polymercaptan has a gel time of 40 s in a 25-g mass.

In certain cases, the separation of metals is a result of kinetic rather than thermodynamic considerations, such as extraction of copper at a lower pH than iron(III) by a commercial 8-hydroxyquinoline derivative, Kelex 100 (Cognis, Inc., Tucson, Arizona, formerly Witco Corporation). If contact is restricted to about 5 minutes then copper extraction is preferred, but when the reaction is allowed to progress to equilibrium then the iron is extracted. This is in contrast to the separation of copper and iron(III) with (3-hydroxyoximes, such as LIX860 (Cognis, Inc., formerly Henkel Corporation) or M5640 (Avecia, formerly Zeneca Specialties), which is thermodynamically controlled. 

Globally, there ate many producers of polymeric plasticizers. In the United States, there are three producers Velsicol Chemical Corporation, Cognis (Henkel), and C.P. Hall Co. Velsicol Chemical purchased the Huls America line of polymeric...
