Fish Eyes are a common problem that occurs in the accurate application of coatings.
What visual appearance do fish eyes take?
Fish eyes appear as round, crater-like holes that penetrate to the substrate.
What probable causes are there for fish eyes?
- Contaminants that prevent coating from wetting out the surface (such as grease from fingerprints or oil in the compressed air)
What suggested solutions can solve the problem?
- Review the handling, cleaning and surface preparation procedures to assure surface is free from contamination prior to coating
- Check for possibility of silicone contamination
- Install/check efficiency of oil/water trap
Support programs, free testing facilities and application advice are often made available from coating manufacturers, helping prevent problems early in the process, saving time and money.
