PVDF coating VS PE coating?
PVDF coating has more talents than PE coating, especially in life span and color tolerence.
Life span of PVDF coating is 10 years longer than PE coating.
Color tolerence of PE coating is smaller than PE coating.
Advantages of painted aluminum coil:
1. Light - weight
2. Fireproof
3. Mothproof
4. Waterproof
5. Anti-cracking
6. Perfect appearance as the material of decoration
