Formulation and testing of a waterborne primer containing chestnut tannin

In this work an aqueous prim er containing chestnut tannin and phosphoric acid was developed and its anticorrosive properties assessed by different conventional tests. Treated Steel ponéis coated with an anticorrosive paint and a topcoat were subjected to the salí spray test, humidity chamber, mecha...
