Isocyanate / Polyol Reaction Inhibitors
« on: February 15, 2011, 08:24:54 AM »
Searching for other Isocyanate / Polyol reaction inhibitors. Have used 2,4 Pentanedione in the past. Currently having side reactions causing pigment discoloration in Urethane coatings systems. Any recommendations?

What are you trying to do?

Are you trying to slow the reaction speed?  Limit the reaction amount between Isocyanate and polyol?

Are you currently adding any catalyst?
