Bundle Description

Adhesion failures and coating defects can ruin product performance, lead to expensive rework, and damage brand reputation. But solving these issues isn’t always straightforward—are defects caused by surface contamination, substrate incompatibility, curing problems, or environmental factors? Without a clear diagnosis, costly trial-and-error methods become the only option.


This expert-led bundle provides a structured approach to identifying, analyzing, and preventing adhesion failures and coating defects before they escalate. Gain the knowledge needed to pinpoint root causes, optimize formulations, and ensure flawless, durable coatings.


Equip yourself with:

  • A deep understanding of adhesion science – Master the fundamentals of substrate-coating interactions and failure mechanisms.
  • Proven troubleshooting strategies – Learn how to identify and correct defects like peeling, cratering, delamination, and poor intercoat adhesion.
  • Best practices for surface preparation – Ensure optimal adhesion by tackling common contamination and treatment issues.
  • Curing and drying optimization techniques – Avoid defects caused by improper film formation, solvent retention, or curing conditions.
