Data outlines typical cured film properties. 5 QUV-A-3 and B-313 ACCELERATED WEATHERING Data illustrates an excellent TGIC-cured tion for outdoor weathering based on M-8911 super-durable polyester. Accelerated weathering test data is outlined for a selected bake schedule. QUV A-3 and B-313 accelerated weathering data illustrates the excellent gloss retention properties obtained using this technology. Superdurable polyurethane (PU) powder coating is used as a control for weather testing. After 1, hours of QUV-A 3 exposure, nearly full gloss retention is observed. Formulation Tips: 1. Replacement of the standard flow modifier with Troy Powdermate 55 1% allows for a smoother surface and higher initial gloss value. 2. The use of Synthron Actiron (tetra butyl ammonium bromide) will allow for faster curing properties. The usage level will be dependent on desired cure schedule. 93.

Weathering test data is outlined for a selected bake schedule. South Florida weathering data illustrates the excellent gloss retention properties obtained using FINE-CLAD M-8911 polyester cured with TGIC. After 48 months of South Florida exposure, 87% gloss retention is realized. 93. FINE-CLAD M TGIC Crosslinker, Araldite PT-81 (1) SUBTOTAL SUBTOTAL TOTAL.
