By Chem Link.

M-1 by Chem Link can be used in almost any situation requiring a sealant, forming a waterproof seal without releasing carcinogens.

M-1® Universal Adhesive/Sealant by Chem Link is a moisture cure, multi-purpose sealant designed to bond and seal to a wide range of construction materials. Chem Link’s flagship polyether product is made with versatility in mind. M-1 is designed to form a tough, elastic and waterproof seal to PVC, EPDM, most metals, wood, glass, masonry concrete, fiberglass and solvent-sensitive foams.

M-1 is most often used for flashing, coping, skylights and HVAC applications, as well as an emergency repair sealant for temporary repair of leaks. It delivers nearly 400 psi shear strength and remains elastic after cure — up to 525% elongation, so it also performs as a structural adhesive.

M-1 covers the building envelope
