ThreeBond 1373B Anaerobic sealant for inserted parts |
ThreeBond 1373B is an anaerobic, extra-strength sealant for joints. It does not cure in air; rather, when it penetrates into narrow gaps in metallic parts, it quickly reacts and cures by polymerization. Thus it bonds or seals the joint. This sealant, including any overflow, cures in ultraviolet irradiation. |
