Dear Sir,
               We are in need of people who do selective coating on base metal that is SS 304 tubesThe objective is to develop new, more efficient selective coatings with both high solar absoprtance (a <0.96) and low thermal emittance (e <0.07) that are thermally stable above 350 C, ideally in air, with improved durability and manufacturability, and reduced cost.  if yes, What is the type of coating and the method of coating that you do. Please do  mail me as early as possible as this is very crucial for our research.
