POM surface decoration is difficult
Problem Phenomenon
POM surface printing and coating are difficult and the adhesion is poor.
Cause Analysis
POM has low surface energy (about 30mN/m), making it difficult for inks and coatings to adhere.
Solution
Surface flame, corona, or plasma treatment; use special inks and coatings.
Key Takeaway
POM surface decoration requires pre-treatment.
