Disclosed is a dual UV and reaction curable, two component adhesive comprising both acrylic chemistry and polyurethane chemistry. The UV curable acrylate component provides a fast cure reaction to generate a tack-free surface. The mixed two component polyurethane cures to a reaction product that provides flexibility and chemical resistance. The adhesive is useful as fold protection for spiral filtration modules. When cured on a membrane the adhesive will maintain integrity and adhesion to membrane after treatments of creasing and soaking at high temperature, pressure, and wide pH ranges.
