Evaluation of the adhesive properties of downhole corrosion resistant polymeric coatings by cathodic disbondment
Evaluation of the adhesive properties of downhole corrosion resistant polymeric coatings by cathodic disbondment
Cathodic Disbondment (CD) of commercially available polymeric coatings has been investigated using a truncated version of the ASTM standard G8-96; one thermoplastic, unfilled polyamide and two thermosetting, filled epoxy based coating systems of two different thicknesses each were studied. For the purpose of comparison, delamination tests were performed on all the coatings using a standard Vickers indenter with a 40 kg weight. The truncated version of the CD test was shown to be effective in evaluating the adhesive properties of the coatings. It was observed that the surface preparations applied to the substrate, before coating was deposited complicated the analysis of the CD test results. Overall, a good agreement was observed between the CD and the delamination indentation tests and the coating systems have been ranked based on their performance in these test methods.

Abstract
Cathodic Disbondment (CD) of commercially available polymeric coatings has been investigated using a truncated version of the ASTM standard G8-96; one thermoplastic, unfilled polyamide and two thermosetting, filled epoxy based coating systems of two different thicknesses each were studied. For the purpose of comparison, delamination tests were performed on all the coatings using a standard Vickers indenter with a 40 kg weight. The truncated version of the CD test was shown to be effective in evaluating the adhesive properties of the coatings. It was observed that the surface preparations applied to the substrate, before coating was deposited complicated the analysis of the CD test results. Overall, a good agreement was observed between the CD and the delamination indentation tests and the coating systems have been ranked based on their performance in these test methods.
