![]() Test results for representative coating systems are presented to indicate the range and type of properties which may be obtained. There are also a large number of standard compositions which can be ordered by trade name and which will satisfy many needs.īecause of the wide range of compositions available only general characteristics of the various systems and additives are reviewed here. Many coating manufacturers prefer to custom blend coatings and work closely with the user to solve his particular problems. The user selects from these a coating based upon economics, intended life, desired transparency, and the expected service conditions. ![]() ![]() There are hundreds of useful clear coating products on the market, formulated from numerous polymers, solvents, and additives. These coatings are organic chemicals which harden at room temperature or with baking and are usually applied in a solvent vehicle. The appearance of these metals can be preserved by applying thin clear protective coatings to their surfaces. Copper and its alloys are extremely resistant to corrosion, but a superficial discoloring tarnish eventually forms with exposure to the atmosphere or handling. Their natural metallic tones range from reddish to silvery and a number of other colors can be obtained by chemical or electrochemical processing. The distinctive colors of copper and copper alloys make them prized for architectural and consumer items and objects of art. Clear Organic Finishes For Copper and Copper Alloys ![]()
