Upjohn 2080® adhesive

What kind of stakes are involved A 1979 "Outlook" annual market survey by the Upjohn Company indicates that the total United States market for polyurethanes would be 2,1+1+1+ million pounds including 1,1+50 million pounds for flexible foam, 615 million for rigid foam and 379 million for elastomers, coatings and adhesives. 

A number of "crude" isocyanates (polymeric isocyanates), undistilled grades of MDI and TDI, are available in the market. Some of these products, such as various forms of crude MDI, have a functionality varying between 2 and 3. They have a lower reactivity and a lower vapor pressure than the corresponding pure isocyanate. They have found extensive use in one-shot rigid foams. However, they are also employed in coating, sealant, and adhesive applications. The Upjohn Chemical Division has published an excellent bulletin on the use and precautions in handling isocyanates, polyurethanes, and related materials (13A).
