Architectural Grade Super Durable Polyester
View / Download PDF Data Sheet
A.S.D. Grade - Is our Architectural Grade Super Durable Polyester Powder Coatings. They are very UV and weather resistant coatings formulated to meet or exceed the AAMA 2604 requirements. The architectural coating specifier may find these coatings well suited for high traffic architectural aluminum components such as doors, railings, and storefronts as they demonstrate superior mechanical properties of impact and scratch resistance when compared to liquid coatings. This grade of coatings also utilizes the superior UV resistant, inorganic, and/or mix metal oxide pigments, These pigment categories are the most impervious to UV degredation and have been proven to retain their original color and resist fading

Metal Preparation and Pretreatment:
A multi stage cleaning and pretreatment system is required to prepare the substrate. A properly operating pretreat system will remove organic and inorganic surface soils, remove residual oxides, and apply a chemical conversion coating to which organic coatings will adhere. Pretreat chemical conversion solutions and rinses must utilize high purity water, and may be of chrome containing conversion, or non-chrome conversion chemistries. Applicator pretreat solutions and processes must comply with the chemical supplier’s procedures and guidelines. Frequent in-plant testing and control of pretreatment is required to insure satisfactory performance of the coating system.
Application:
A.S.D. Grade coatings are designed for application by electrostatic spray – manual or automatic. Reclaim is acceptable, provided there is no incident of cross-contamination. Reclaimed coatings which contain special effect micas should be evaluated for consistency. When applying A.S.D. Grade, some experimentation is typical with regard to gun kV settings and air velocities to maximize transfer efficiency and achieve a consistent coating thickness. Curing by means of gas fired convection oven with proper exhausting is the industry norm. Oven profiling is required to evaluate the cure process.
Precautions:
All dusts are respiratory irritants. The coating area must be properly ventilated. If skin contact occurs, wash with mild, soapy water. If eye contact occurs, flush with water immediately and secure medical attention. Dust clouds of any finely divided organic material can be ignited by electrical sparks or open flames. All equipment must be electrically grounded to preclude buildup of static electricity. Ensure adequate oven ventilation when curing this product. See MSDS for further precautions.
Storage Stability:
The maximum storage temperature for this coating is 80°F at 50% Relative Humidity. Under these conditions, a shelf life of 12 months is expected.
