1P-223 : Metal Acetylacetonate as both a Radical Initiator and a Catalyst for Polyurethane in Dual-Curing Reaction at low temperature

The goal of our research has been to realize low temperature curing based on dual curing reaction which is accompanied with radical initiator and catalyst of urethane reaction using metal acetylacetonates (Metal(acac)n) The effect by the type of metals and number of acetylacetonate on each reaction is mechanistically studied and how they lead to a result in curing behaviors when both reactions were applied together by exploiting a series of Mn(acac)3, Mn(acac)2, Co(acac)3, Co(acac)2, Fe(acac)3, Zn(acac)2 in acryl-polyol resin and PL 350, which is commercial blocked isocyanate.
