  • ANAEROBICALLY CURABLE COMPOSITIONS
    Publication number: 20100006208
    Abstract: Dry-to-the-touch compositions containing a curable polymeric matrix and a curable anaerobic composition present within the polymeric matrix are disclosed. In a particularly desirable form, the compositions are moisture curable. The compositions are non-flowable at high temperatures and have an improved solvent resistance once cured.

  • Cure accelerators for anaerobic adhesive compositions
    Patent number: 6723763
    Abstract: The present invention provides a new class of materials effective as accelerators for curing anaerobic adhesives. The addition of these materials into anaerobic adhesives as a replacement for conventional curatives, such as APH and/or toluidines, surprisingly provides at higher cure speeds and comparable physical properties for the reaction products formed therefrom.
