UV Curable Cylinlock® 820 is a fast curing, high-strength anaerobic adhesive designed to retain and seal cylindrical assemblies. Curing occurs when adhesive is confined between mating surfaces. The cured adhesive is a thermoset plastic suitable for exposure to most solvents. Augments or replaces press fits, set screws, pins and other mechanical retaining methods. Avoids heavy press fits due to rapid cure. Cylinlock® 820 cures quickly at room temperature without the need for surface activators or heat to join cylindrical assemblies. Fixturing strength develops in five minutes or within 15 seconds by exposing the edge fillets to high intensity long wavelength UV light (365 nm). Full strength will be reached in 24 hours.
