Anaerobically curable composition and process for preparation thereof |
摘要 |
A novel anaerobically curable resin composition of one-part type is provided. The composition consists essentially of the following components (a), (b) and (c) in the specified amounts; the component (a) being a mixture of polymerizable components consisting of (i) an addition-reaction product of a polybutadiene-based liquid rubber, a polyisocyanate and a hydroxyl group-containing methacrylate, and (ii) a polymerizable methacrylate; the component (b) being a salt of o-benzoic sulfimide with a specified amine; and the component (c) being an ammonium or amine salt of an aminopolycarboxylic acid. The process for preparation of the composition comprises the step of adding the specified amounts of the aminopolycarboxylic acid or an alkali metal salt thereof and an ammonia water or a volatile organic amine to the component (a), the step of stirring and heating the mixture to remove volatile matters partly until the pH is decreased to 9 or lower, and the step of adding thereto the component (b).
