  • Publication number: 20240052219
    Abstract: An anaerobically curable composition comprising: a liquid anaerobically curable component; a solid anaerobically curable component; a solid polyether thermoplastic polyurethane resin; and a curing component for curing the anaerobically curable components. Advantageously, the compositions of the invention are substantially solid and may be used as threadlockers.

  • Publication number: 20230272186
    Abstract: The present invention relates to cure accelerators useful for anaerobic curable compositions, such as adhesives and sealants. The cure accelerators may be embraced generally within the structure below where X is CH2, O, S, NR?, CR?R?? or C?O; R is hydrogen or (meth)acryl; R6 is hydrogen, halogen, amino, carboxyl, nitro, alkyl, alkenyl, alkynyl, hydroxyalkyl, hydroxyalkenyl, hydroxyalkynyl, or alkaryl; and A and A1 are each individually selected from hydrogen or taken together create a ring structure of 5 to 12 total ring atoms, wherein the ring structure may be cycloaliphatic, cycloheteroaliphatic or aromatic or combinations thereof with or without substitution by one or more hydroxyl or (meth)acryl groups; and n is 0 or 1, provided that when R is hydrogen, A and A? cannot both be hydrogen or taken together cannot be naphthyl.

  • Publication number: 20220089920
    Abstract: An anaerobically curable composition comprising: (a) a non-encapsulated liquid anaerobically curable monomer forming a liquid phase; (b) a solid component dispersed as a solid phase within the liquid phase formed by the non-encapsulated liquid anaerobically curable monomer; wherein the solid component has (meth)acrylate functionality and: (i) is in particulate form with the particles having a particle size in the range from about 80 ?m to about 300 ?m; and (ii) has a melting temperature of from about 50° C. to about 90° C.; and (c) a curing component for curing the anaerobically curable composition within the liquid phase. The anaerobically curable composition can easily be coated onto substrates such as threaded fasteners or other parts in its flowable form and then converted to anaerobically curable composition in solid form.

  • 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.
