Typical uses would be window and door frames, railing and fencing, outdoor displays and light fixtures. These powder materials are comparable to two-component liquid polyester coatings and can be applied in a single coat of 1.5 to 3.0 mils. These products are formulated with resin systems and pigmentation to meet 2604's five-year standard for gloss retention and color loss. The technology for the 2604 standard is typically a TGIC polyester or super-durable powder. Yes, there are powder formulas that can meet the American Architectural Manufacturers Association's standards (AAMA 2604-13).
Can powder coatings meet AAMA 26 standards? What other pros and cons of powder versus liquid should we consider?Ī. We hear conflicting stories about the UV resistance of powder when compared to high-performance liquid coatings. We currently perform both liquid and powder coating on various parts and have been considering using more powder coatings on our architectural aluminum extrusions to reduce our VOCs (volatile organic compounds).
