ALPHATEC® 442 is a modified epoxy resin-based concrete primer with good tolerance for wet surfaces. It can be applied on concrete, wood, or steel surfaces, and shows tenacious adhesion even when cured in the presence of water. It forms a good basis for the application of lining, flooring, or patching mortar systems, particularly when surface preparation methods such as high-pressure water blasting are the only practical approach. ALPHATEC® 442 is used in underwater repairs of jetties, piers and wharves, as well as in wet areas in industrial plant such as steel rolling mills. It is frequently used in conjunction with ALPHATEC® 741 Patching Compound.
