Fish Eyes

Appearance

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.
