ChemLink DuraLink 35 Multi-Purpose Sealant, Black 10.1 oz Cartridge
ChemLink DuraLink 35 is a moisture-curing polyether joint sealant for windows, door frames, parapets, masonry, and siding. The solvent-free formula has no isocyanates and forms a tough, elastic seal in damp, dry, or cold conditions without shrinking or bubbling on damp surfaces. Typical work includes Kynar 500 PVDF coated metal, glass, and concrete, and it can be applied as low as 32°F. For higher-movement curtain wall and siding joints, use ChemLink DuraLink 50, a different formula.
