M-1® Universal Adhesive/Sealant is Chem Link’s flagship polyether product. Designed for bonding and sealing a wide range of construction materials, it can be used on PVC, EPDM, most metals, wood, glass, masonry concrete, fiberglass and solvent-sensitive foams. It works in almost any situation requiring a sealant. Plus, M-1 is a solvent-free, versatile product with the ability to form a tough, waterproof seal on most roofing materials.

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.
