Failure Analysis of Paints and Coatings
Revised Edition
by Dwight G. Weldon

From thickness and adhesion issues to wear and flow, there are many reasons why, despite advances in surface preparation technology and application techniques, paints and coatings can fail.

Whilst failures can be inevitable, premature failures are often avoidable; sound knowledge of coatings chemistry and a rigorous application of the techniques discussed here will aid the investigator to solve thse failures quickly and efficiently.

Failure Analysis of Paints and Coatings:

  • Entirely devoted to the failure analysis of coatings and paints – an “excellent reference to a select market”.
  • Latest edition contains new material on surface preparation, transfer of salt to steel from contaminated abrasive, effect of peak density on coating performance, on galvanizing, silane-modified coatings, polyurea coatings, polyaspartics, and powder coatings and on dry spray.
  • Balances scientific background and practical advice, giving both the theory and applications in a slim, easily readable form.
  • Includes case studies of laboratory tests.
  • Written by an author with over 25 years of experience in the paint and coatings industry
