Patent number: 11274190
Abstract: The present invention relates to cure accelerators useful for anaerobic curable compositions, such as adhesives and sealants. The cure accelerators are embraced within where X is CH2, O, S, NR4, CR5R6 or C?O, wherein R4, R5, and R6 are each individually selected from hydrogen, halogen, amino, carboxyl, nitro, alkyl, alkenyl, alkynyl, hydroxyalkyl, hydroxyalkenyl, hydroxyalkynyl, or alkaryl; R is one or more of hydrogen, alkyl, alkenyl, alkynl, hydroxyalkyl, hydroxyalkenyl, or hydroxyalkynl; R1, R2, and R3 are each individually selected from hydrogen, halogen, amino, carboxyl, nitro, alkyl, alkenyl, alkynyl, hydroxyalkyl, hydroxyalkenyl, hydroxyalkynyl, or alkaryl; R7 is hydrogen or CHR8R9, where R8 and R9 are each individually selected from hydrogen, halogen, amino, carboxyl, nitro, alkyl, alkenyl, alkynyl, hydroxyalkyl, hydroxyalkenyl, hydroxyalkynyl, or alkaryl; and n is 0 or 1. A particularly desirable example is 1,2,3,4-tetrahydrobenzo-h-quinolin-3-ol.
