Hypersensitivity to Sta-Lok and Loctite anaerobic sealants

Three cases of allergic contact hypersensitivity to Sta-Lok and Loctite anaerobic sealants are reported. These two anaerobic sealants constitute a +100 million annual market in industrial sealants used to join metal surfaces together. To the best of my knowledge, these are the first reported cases of allergic contact hypersensitivity to these agents.
