| ADIPRENE BL-16 is a liquid urethane elastomer with blocked isocyanate curing sites, which can be activated by heating. The blocked curing sites allow protracted storage of the polymer in the presence of moisture and active vulcanizing agents. Diamine-cured ADIPRENE BL-16 yields vulcanizates essentially equivalent to those of ADIPRENE L-167. These products have high tensile strength and excellent oil and abrasion resistance. ADIPRENE BL-16 is well suited as a vehicle for abrasion resistant coatings for fabric and rubber, and for solvent-resistant adhesives.&& |
