Frequently Asked Questions
- Q: What coating type is recommended for HVAC ductwork?
- A: PE (Polyester) is commonly used for standard HVAC applications. For environments with higher humidity or corrosive conditions, SMP (Silicone Modified Polyester) is recommended for enhanced durability.
- Q: Can this product be used for both indoor and outdoor ductwork?
- A: Yes. For indoor applications, standard PE coating is sufficient. For outdoor or exposed ductwork, we recommend SMP or HDP coating for better weather resistance.
- Q: Is the prepainted surface suitable for duct sealing and joining?
- A: Yes. The coating is designed to withstand standard ductwork joining methods including seaming, locking, and the application of duct sealants without compromising the coating integrity.
