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.
·
Is a fast-curing and extra-strength type.
·
Cures well at low temperature.
·
Has low viscosity.
·
Has the added feature that it cures in ultraviolet irradiation.
