What makes epoxy-phenolic coatings on metals ubiquitous: Surface energetics and molecular adhesion characteristics

JOURNAL OF COLLOID AND INTERFACE SCIENCE, 608, 634–643.

By: Y. Kotb n, A. Cagnard*, K. Houston*, S. Khan n , L. Hsiao n  & O. Velev n 

author keywords: Adhesion; Polymer; metal interactions; Epoxy coatings; Contact angle; Surface energy; Pull-off test; XPS
MeSH headings : Epoxy Compounds; Epoxy Resins; Physical Phenomena; Steel; Wettability
topics (OpenAlex): Surface Modification and Superhydrophobicity; Epoxy Resin Curing Processes; Corrosion Behavior and Inhibition
TL;DR: Theoretical adhesion results reveal a superior adhesion of epoxy compared to phenolic resins, and epoxy resins having a higher content of epoxide-to-hydroxyl groups show improved theoretical and practical adhesion. (via Semantic Scholar)
