LOW VISCOSITY ISOCYANATE PREPOLYMERS BLOCKED WITH PHENOLS OBTAINABLE FROM CASHEW NUT SHELL OIL, METHOD FOR THEIR PREPARATION AND THEIR USE

摘要

The present invention concerns new, solvent-free, space-temperature hardening, blocked isocyanate prepolymers and a process for their manufacture. In addition, the present invention concerns the use of these blocked isocyanate prepolymers for the manufacture of solvent-free reactive systems and their use in the manufacture of adhesives, sealing masses, castings, moulds or coatings hardening at room temperature.
