DURANAR XL COATINGS - Superior Metals

1 SYSTEM OVERVIEWCOMMERCIAL USESDURABILITYPRODUCT DESCRIPTIONDURANAR XL fluoropolymerextrusion COATINGS are three- andfour-coat systems consisting of(three-coat system) a patentedprimer, a durable color coat, anda clear top coat or (four-coat system) a patented primer, a barrier coat, a durable color coat, and a clear top coat. Theycombine PPG proprietary resinand pigment technologies with70% of the resin system beingfluoropolymer base XL extrusion COATINGS have demonstratedproven performance on exterioraluminum surfaces, especially in seaside or corrosive industrialenvironments. They are highlyresistant to chalking, fading,chipping, and peeling whenproperly applied by an approvedapplicator. DURANAR XL COATINGS resist dirt collection and chemical staining, and cansignificantly reduce maintenanceand restoration costs over exceed AAMA 2605 and ASCA 96 (ArchitecturalSpray Coaters Association) performance specifications andare the architectural extrusioncoatings of choice when exceptional durability and performance are required inaggressive DATADURANAR XL extrusion COATINGS provideoutstanding durability and performance ina variety of exterior architectural applications,and have gained widespread acceptance dueto their proven, coater-friendly applicationproperties.

2 The DURANAR XL clear topcoat is an essential component of the three-coat system, providing added protectionagainst ultraviolet, humidity, and chemicalattack. The four-coat system (which includesa barrier coat between the primer and colorcoats) is intended for use with color coatscontaining certain aluminum flake pigments*.The XL top coat is required over somebrightly pigmented DURANAR COATINGS andall colors containing metallic flakes. TheXL top coat may also be specified over anyDURANAR coating to improve its overallperformance and reduce maintenancerequirements**. DURANAR XL COATINGS provide excep-tional aesthetics. In aggressive environments,generally defined as industrial areas or seacoast locations, DURANAR XL coatingsdemonstrate outstanding color and glossretention, increased abrasion resistance,and added protection against atmosphericcontaminants such as acid rain.

3 DURANAR XL spray-applied extrusioncoatings are formulated to provide the ulti-mate performance against weathering inaggressive environments. The DURANARXL system is the coating of choice for useon pre-formed aluminum components suchas storefronts, curtainwalls, windows, andlouvers under these XL COATINGS are chemically inert,providing outstanding resistance against colorand gloss fade and environmental stress suchas acid rain and ultraviolet attack. All pigmentsare tested for a minimum of ten years insouth Florida prior to approval for use inany DURANAR XL coating , DURANAR XL COATINGS aretested at exposure sites throughout the worldin all types of climatic and industrial condi-tions to ensure the COATINGS performanceand durability in aggressive XLCOATINGSDURANAR and the PPG logo are registered trademarks of PPG Industries, Inc.

4 * The appearance of metallic and pearlescent finishes may vary upon factory application due to differencesin spray equipment, spray techniques, film thickness, and curing conditions. It is strongly recommendedthat final color approval is made from actual production pieces, including clear top coat when required,not laboratory prepared samples. Limits for acceptable production variations are to be establishedbetween the approval source and applicator.** The XL top coat may affect the final appearance of lightly pigmented DURANAR DURANAR XL 6/6/03 4:55 PM Page 1 PRODUCT DATAC olors AvailableA range of colors and polychromatics, including metallics, micas and bright colorsDry Film ThicknessASTM mil mil min. barrier coat (if applicable) mil min. color mil clear top coatGlossASTM D523 @ 60 Medium glossPencil HardnessASTM D3363F Hatch Adhesion1/16 wet and dryExcellent No removalDirect Impact1/10 distortionExcellent No removalAcid ResistanceASTM D130815 minutes No attack10% muriatic acid spot testAlkali ResistanceMortar pat test24 hours No attack100% relative humidity @ 100 FDetergent Resistance3% immersion @ 100 F72 hours No attackSalt Spray ResistanceASTM B117, 4000 max.
