Problembeschreibung
Adhesion between substrate and coating is good the first time but poor on repetition.
Ursachenanalyse
Changes in substrate surface condition (moisture absorption, oxidation) affect coating adhesion.
Lösung
Properly store substrates with shelf-life management; pre-treat before use (plasma, etc.).
Wichtigste Erkenntnis
PCTG coating adhesion depends on substrate condition management.
