<p>PURPOSE:To obtain the titled sheet which can be easily mounted on an under- water structure and is excellent in durability, by forming a primer layer and an adhesive layer on one surface of a particular Cu-Ni alloy plate. CONSTITUTION:100pts.wt. elastomer (e.g., natural rubber) is blended with 20-300 pts.wt. tackifier resin (e.g., rosin resin) and 30-200pts.wt. epoxy resin. The blend is dissolved in an org. solvent to obtain a primer compsn. (A) having a concentration of 1-50wt%. Separately, an elastomer comprising a natural or synthetic rubber is blended with a tackifier resin, a filler, a crosslinking agent, an auxiliary crosslinking agent and an antioxidant to obtain an adhesive (B) having an excellent aging resistance. The component (A) is applied on one surface of a Cu-Ni alloy plate comprising Cu and Ni in a weight ratio of 100:0-80:20 to form a primer layer 2 having a solid content of 1-20g/m<2>. The component (B) is applied on the primer layer to form a 20-1,000mu-thick adhesive layer 3, followed by application of a release paper 4 to the adhesive layer 3.</p> |
