The estimated growth rate to the year 2000 for total MDI is 4—5% in the United States and 6% globally. In 1987 and 1988 U.S. plants were estimated to be 96 and 97% utilized (39). Additional capacities of over 400,000 t by the end of 1993 have already been announced (40—44). Approximately 20% of the total MDI manufactured in the United States is exported (38,39,45). Of the 500,000 t of PMDI mixtures manufactured annually in the United States it is estimated that only 75,000—100,000 t are sold as 4,4LMDI. The current bulk selling price for 4,4 -MDI is 2.75/kg and for PMDI 2.20. The 4,4 MDA sells for 5.00—6.50/kg and cmde PMDA is 2.90—3.25/kg. Approximately 450—900 t of pure 4,4 -MDA are imported (46,47), MDA and PMDA products are sold commercially imder the names of MDA (BASF), Araldite Hardener (CIBA-GEIGY), Curithane (Dow), Ancamine (Pacific Anchor), andTONOX (Unicoyal). 

More recent efforts have focused on developments that create true hybrids. For example, blocked isocyanate prepolymers have been mixed with epoxy resins and cured with amines [68-70]. These blocked prepolymers will react initially with the amines to form amine-terminated prepolymers that cross-link the epoxy resin. Several blocked isocyanates are commercially available. The DESMOCAP (Bayer) llA and 12A products are isocyanates (believed to be blocked with nonylphenol) used as flexibilizing agents for epoxy resins. ANCAREZ (trademark. Pacific Anchor, Inc.) 2150 is a blocked isocyanate epoxy blend used as an adhesion promoter for vinyl plastisols. A one-package, heat-cured hybrid adhesive was reported consisting of isophorone diisocyanate, epoxy resin, and a dispersed solid curative based on the salt of ethylenediamine and bisphenol A [71]. Urethane amines are offered commercially that can be used with epoxy resins to develop hybrid adhesive systems [72].
