A STUDY ON THE CHARACTERISTICS AND PRACTICALITY OF A NEW INORGANIC ZINC SHOP PRIMER

Where heavy anti-corrosive paints containing inorganic zinc are used for priming large steel structures they attract considerable interest. The usual inorganic zinc shop primers present problems associated with, for example, suitability for spraying, gas cutting, weldability, and compatibility with the over-coats used. The Authors describe the development of a new inorganic zinc primer to overcome these difficulties. The following results have been obtained: 1) It has good spraying characteristics with an existing spray system and is less "dirty" in use than the usual inorganic zinc primer. 2) It has excellent gas-cutting properties and can be fillet welded by the submerged-arc process. 3) It has better corrosion resistance and compatibility with over-coating paints than the usual inorganic zinc shop primer, even with chlorinated-rubber paints in underwater areas, e.g. ship bottom coating. 4) It has the other properties possessed by existing zinc primers.
