Lupranate® Prepolymers (Quasi-)

 

BASF offers MDI prepolymers (quasi) based on reaction with a variety of resins, including polyether, polyester, PolyTHF®, and others. A prepolymer results from the reaction of excess MMDI with a hydroxyl terminated resin. The exact term, quasi-prepolymer, refers to a reaction product that is a mixture of prepolymer (capped-resin) and excess MMDI.
