HEARD AT THE CORROSION CONVENTION: Part II, 2nd Day

Abstract

Paints and the Part they Play in the Fight Against Corrosion. H. Hollis, B.SC., A.R.I.C., and L. J. COLEMAN (Chemical Inspectorate, Ministry of Supply). Dr. W. F. Higgins (Magnesium Elektron Ltd.) stated that the importance of surface preparation could not be too greatly stressed. Continuing, he said that the authors had made what seemed to him to be an extraordinary statement, although up to a point it was really common sense. They had said that a primer was applied to protect the metal surface, and then the top coat or maybe the intermediate coat was applied to protect the primer. He gathered they were not referring to protection merely against physical damage. But why did they do that? It should not be necessary. On the previous day it was stated by Mr. Rogers that it was done because the ratio of binder to solid was small, and therefore there was not good adhesion. Dr. Higgins suggested that, if a primer were applied to the metal surface and it had not good adhesion, one could not make it good by putting another coat of paint on top of it.
