Understanding AAMA Most commonly referenced coating standards for coated fenestration products: • Voluntary specifications, performance requirements and test procedures for coatings on aluminum extrusions and panels.

Measuring durability Florida natural exposure is a universal testing procedure • Florida climate combines • • • Strong UV attacks High temperatures High humidity Florida testing consists of observing color variation and gloss change in time

Color Selection Liquid & Powder Coatings: • Architectural Culture & Market • Application Method • Durability (AAMA / Qualicoat) • Color • Resins • Characteristics: • • Multiple vs. Single Coat • Metallic Flop (Directionality) • VOC Examples

Color Selection Coatings are available in a wide selection of colors. But as durability specification increases, the range of colors reduces, so does the gloss selection. • AAMA 2603 – Maximum Colors Available • AAMA 2604 – Reduced Selection • AAMA 2605 – Limited to Neutral Colors Key is to achieve a good combination of resin and color selection to extend durability. Ex. White / Loss Gloss will most likely last for longest time.

Resins used to achieve AAMA specifications Different resin types commonly used in the metal industry: Acrylic liquid AAMA 2603 Polyester powder AAMA 2603 PVDF 50% liquid AAMA 2604 Super durable polyester powder AAMA 2604 PVDF 70% liquid AAMA 2605 Fluorocarbon powder FEVE AAMA 2605

Fluorocarbon Polymers Resins PVDF Resin BRANDS FEVE Resin BRANDS

FEVE in Powder Coatings Based on Hyper Durable Technology – fluorocarbon chemistry applied to a powder coating to give the ultimate in exterior durability • The carbon/fluorine bond is one of the strongest molecular bonds • FEVE is a true powder coating alternative to liquid PVDF Powder Coatings • • • A dry powder paint with no solvents or VOCs • Attractive finish available in many colors and metallic effects • Meets the world’s toughest quality standards Applied by industrial coaters to aluminum Gives outstanding weather stability combined with high chemical resistance and low soiling

Single Coat vs. Multiple Coats • Single coat (monolithic properties) • Multiple coat (depth appearance) • Electrostatic application equipment • Normal application equipment • 2. 5 to 4 mils DFT • 1. 3 to 1. 8 mils DFT • High Transfer Capabilities (zero waste) • Lower Efficiency (% of material utilized) Powder Liquid

Metallic Color (90° vs. Flop) Mica / Metallic Flake • Until recently, the appearance of metallic finishes in powder couldn’t reach the depth and brightness of liquid PVDF. • Innovation lead to broad range of bright, metallic and matt finishes. • Liquid and Powders offer different appearances: • View at arm’s length, holding panels at a 90° angle, with sun shining over your shoulder (or view in D 65 light booth, arm’s length, holding panels at a 90°)

Toughness Powder Coatings / FEVE offer outstanding toughness perfect for specifying: • • High abrasion areas Reduced Touch Up / Installation

AAMA Specification ASTM B 117 AAMA 2605 – Corrosion is now tested at 2000 HR G 85 A 5 Cyclic Corrosion *

Environmental VOC • • Powder has no VOCs, thus it results in fewer emissions. In liquid coatings, VOCs are destroyed in most production in USA, thus eliminating 95% of emissions

Environmental EPD What is an EPD? • Independently verified and registered certified Eco Footprint document. • Transparent and comparable information about the life-cycle environmental impact of products • It can help towards LEED points Results: • It analyses upstream (raw materials) and downstream (application).

Corrosion Specification: Aluminium Category Corrosivity Examples (outdoor) C 1 Very low Dry or cold zone, atmospheric environment with very low pollution and time of wetness, e. g. certain deserts, Central Arctic/Antarctica C 2 Low Temperate zone, atmospheric environment with low pollution (SO 2: <5 μg/m 3) e. g. rural areas. Dry or cold zone with short time of wetness Medium Temperate zone, atmospheric environment with medium pollution (SO 2: 5 μg/m 3 to 30 μg/m 3) or some effect of chlorides, e. g. urban areas, coastal areas with low deposition of chlorides Subtropical and tropical zone, atmosphere with low pollution C 4 High Temperate zone, atmospheric environment with high pollution (SO 2: 30 μg/m 3 to 90 μg/m 3) or substantial effect of chlorides, e. g. polluted urban areas, industrial areas, coastal areas without spray of salt water or, exposure to strong effect of de-icing salts Subtropical and tropical zone, atmosphere with medium pollution *C 5 Very high Temperate and subtropical zone, atmospheric environment with very high pollution (SO 2: 90 μg/m 3 to 250 μg/m 3) and/or significant effect of chlorides, e. g. industrial areas, coastal areas, sheltered positions on coastline Extreme Subtropical and tropical zone (very high time of wetness), atmospheric environment with very high pollution (SO 2: higher than 250 μg/m 3) including accompanying and production factors and/or strong effect of chlorides, e. g. extreme industrial areas, coastal and offshore areas, occasional contact with salt spray C 3 *CX

Architectural Coatings Liquid & Powder Coatings: • Architectural Culture & Market • Application Method • Durability (AAMA / Qualicoat) • Color • Resins • Characteristics: • Multiple vs. Single Coat • Metallic Flop (Directionality) • VOC • Examples

AAMA 2603 / Qualicoat class I • • Mostly used for interior applications Also used in exterior areas with limited exposure to UV 1 year Florida color retention (per AAMA) Many color options available for powder and liquid coatings. Torre el Faro, Argentina

AAMA 2604 / Qualicoat Class II • Higher durability standard than AAMA 2603 • 5 year Florida color & gloss retention (per AAMA) • Used for exterior applications Globally for over 30 years Mission Viejo Hospital, California (1991) The Shard, UK

AAMA 2605 / Qualicoat class III • Used for exterior applications on prestigious buildings or in extremely high weatherable areas • Highest durability standard in the market. 10 year Florida color & gloss retention (per AAMA). • Reduced color and gloss selection 35 Hudson Yards, NYC

Conclusion: Architectural Coatings Powder or Liquid technology Describe the way the paint was applied • Means & Methods of Construction • Either can perform well depending on the performance required Factors that will drive one technology vs. another: • Owner / Curtain Wall / Building Components / Consultants • Coil, Extrusion, Elevator, Handrails, • Region of the project and application • Europe (Powder), US (Both), China (Both), etc. • Transportation, Installation & Maintenance factors • Environmental Factors

How to Specify Example: Monumental project going up in Miami: 1. 2. 3. 4. 5. Determine parts to be coated DURABILITY • AAMA 2605 or equivalent • FLUOROPOLYMERS: PVDF, FEVE or equivalent Determine color in liquid / powder / touch up Determine environmental requirements REQUIRE AAMA CERTIFIED APPLICATORS Still in doubt? Ask your trusted coatings manufacturer for a sample specification.
