Slide 10: Focus On Kynar Film
3 Market Presentation - Photovoltaic Focus On Kynar Film ®
Slide 11: Why 3-Layer Kynar PVDF Film?
Why 3-Layer Kynar® PVDF Film ? PVF 41% F PVDF VARIABLE F Exposed layer is Kynar® Film 59% F pure PVDF Low & FEVE variable F F Market Presentation - Photovoltaic
Slide 12: Patented 3-Layer Kynar Film Technology
Patented 3-LAYER KYNAR® Film Technology → Surface layers: Pure KYNAR® PVDF with 59% Air Side Fluorine - High Moisture Barrier - Completely UV resistant Adhesive - Very broad Chemical Resistance - High Flame resistance PVDF PET SKINS → Middle pigmented layer: High KYNAR® PVDF content - Same Fluorine
Slide 13: PVDF Weathering Comparison
PVDF Weathering Comparison t=0 after 7800 hrs after 9200 hrs control QUVA exposure QUVB exposure KYNAR® FILM PVDF Monolayer Variable PVDF formulations means UV degradation Holes Cracks → Competitive monolayer films are not pure PVDF ! Extreme Surface Erosion → Ask for the KYNAR brand to be sure !
