Poor adhesion of ETFE to substrates
Sorun Belirtisi
Insufficient adhesion of ETFE coating or lining to metal or other substrates
Neden Analizi
ETFE surface energy is extremely low (similar to PTFE); lack of effective surface treatment
Çözüm
Sandblast the substrate to roughen and increase mechanical interlocking; plasma/corona/sodium-naphthalene solution treatment to increase surface energy; use primer
Temel Çıkarım
The low surface energy of ETFE is the core difficulty of its bonding processing
