It cures only when confined without air between close-fitting surfaces, so it does not set outside the joint, and Permatex describes it as non-corrosive to aluminum and cast iron. Repair shops and maintenance crews apply it as a form-in-place gasket on gearbox and engine castings, transmission pans, transfer cases, pumps and housings, or for an on-the-spot repair when a conventional gasket is not available.\u003c\/p\u003e\u003cp\u003eThe Safety Data Sheet (US OSHA and Canada WHMIS, revision of February 4, 2025) lists the product as a skin irritant (Category 2), serious eye irritant (Category 2A), skin sensitizer (Category 1), possibly carcinogenic (Category 1B) and a repeated-exposure organ toxicant (Category 2); signal word Danger. Wear gloves and eye protection and read the SDS before use. Not for pure oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidizers.
