Chem Link M-1® F1274 10.1 oz Marine Structural Adhesive and Sealant Cartridge 12 per Case. M-1 Marine is a moisture cure polyether adhesive/sealant formulated for applications above or, post cure, below the water line and in areas where outgassing and solvents are not tolerated. The product is solvent free and contains no isocyanates. It will not shrink upon curing, will not discolor when exposed to ultraviolet light and will not "out-gas" or bubble on damp surfaces as urethane sealants often do. The sealant has resilient elastomeric properties and excellent adhesion to most substrates. It can be used effectively in many difficult site conditions, cures in wet or dry climates and low temperatures.
