Frequently Asked Questions
- Q: What is the difference between PPGI and PPGL for sandwich panels?
- A: PPGL uses Galvalume steel as the substrate, offering superior corrosion resistance compared to PPGI. For sandwich panels used in high-humidity or corrosive environments, PPGL is the preferred choice.
- Q: What coating type is best for sandwich panels?
- A: PE (Polyester) is commonly used for interior panels and standard applications. SMP and HDP are recommended for exterior panels requiring better weather resistance. PVDF is preferred for premium applications.
- Q: Can the adhesive used in sandwich panel manufacturing bond to your PPGL surface?
- A: Yes. Our PPGL surface is specifically designed for optimal adhesive bonding. We can provide surface treatment options to enhance adhesion for specific panel manufacturing processes.
