Round, crater-like
holes that penetrate the substrate.
Probable Causes
Contaminants
that prevent coating from wetting out the surface (such
as grease from fingerprints or oil in the compressed air).
Suggested Solutions
1. Review the
handling, cleaning and surface preparation procedures to
assure surface is free from contamination prior to coating.
2. Check for possibility of silicone contamination.
3. Install/check efficiency of oil/water trap.
