Lupranate® Polymeric MDI Blends and Derivatives

 

Starting with core PMDI and MMDI, BASF has developed a line of isocyanate blends and derivatives that deliver the custom properties demanded in CASE applications. For example, the 2,4’-MDI enhanced polymeric MDI’s are selected for floor coatings that require extra working time, but ultimately maintain cross-linking potential. BASF’s PMDI Blends and Derivatives are often made-to-order in drums, totes, and tank truck quantities.
