The L2 adhesive platform features a proprietary 3M modified acrylic adhesive that withstands temperatures up to 225 oF (107oC) and offers high initial tack, excellent peel adhesion and strength to many open and closed cell foams. It bonds well to Polyurethane (PU) Ether, PU Ester, cross-linked Polyethylene (PE) foam, EPDM foam, Neoprene foam, Nitrile foam, and microcellular urethane. All L2 constructions feature an 83# kraft colored unprinted polycoated kraft (PCK) liner for superior processing.
