M-1® Universal Adhesive/Sealant

M-1 adheres to a wide range of construction materials including PVC, EPDM, most metals, wood, glass, masonry concrete, fiberglass and solvent-sensitive foams so it is works in almost any situation requiring a sealant. Yet it delivers nearly 400 psi shear strength and remains elastic after cure—up to 525% elongation, so it also performs as a structural adhesive.
