ArenNano Black Stainless black sol gel on Stainless Steel Arceo Engineering, 12 sept. 2016 1

ArenNano Black Stainless  Context of the NANOSOL project Transparent protection layer Top coat + protection Top coat Primer Metal Metal Functional coating Protection of organic layers • • Coating for home appliances Performance comparison • with conventional coatings Anti finger print coating Arceo Engineering, 12 sept. 2016 2

ArenNano Black Stainless  Coating based on the Nanoxid product range: application by spray or roll coating Colloïdal solution – SiO 2 drying liquid film application  Black sol gel = Nanoxid (transparent) + carbon particles Arceo Engineering, 12 sept. 2016 3

ArenNano Black Stainless  Application on brushed stainless steel – trial on Arceo Engineering roll coating line   Coating thickness Aspect (color and gloss) 1 µm 5 µm  The « metallic grinded look » is kept alive  The aesthetics depend on the layer thickness : black  bronze  Gloss compared to grinding direction :  Gloss parallel to grinding //: 40  Gloss perpendicular to grinding : 12 Arceo Engineering, 12 sept. 2016 4

ArenNano Black Stainless  Mechanical properties   Standard tests Qualitative tests • • Impact resistance: 18 J Adherence on flat surface and crossed surface : • T-bend 100% adherence  Excellent adherence on the substrate Arceo Engineering, 12 sept. 2016 5

ArenNano Black Stainless  Mechanical properties   Test Erichsen: up to 6 mm Test Marciniak 13% deformation  No cracks, no delamination  No color change on deformed zones  Ability for deepdrawing Arceo Engineering, 12 sept. 2016 6

ArenNano Black Stainless  Mechanical Properties : hardness  Indentation: measurement of hardness and elasticity module  For micrometric coatings  control of the indentation depth at nanometric scale  Nanoindentation: load ~100 mN, indentation depth ~ 1-2 µm Hardness calculation: Coating Hardness Young Module (Gpa) (Gpa) Anti finger print varnish 0,2 3-5 Black sol gel 0,2 4 304 steel : H= 3-5 GPa Arceo Engineering, 12 sept. 2016 7

ArenNano Black Stainless  Mechanical characteristics : tribologic properties  Measurement of the friction coefficient  tribometer pawn-disc  Low friction coefficient: µ ~0,3  Good resistance to wear Arceo Engineering, 12 sept. 2016 8

ArenNano Black Stainless  Resistance to friction weight (0,25 to 1 kg) Observation quotation No scratches 0 Low density of scratches 1 Medium density of scratches 2-3 High density of scratches 4 Completely scratched 5 Arceo Engineering, 12 sept. 2016 9

ArenNano Black Stainless Référence Référence + 10 * back and forth with Référence 10 AR  10 AR // soft cloth  scratches emanate from the scratching device  soft cloth allows easy cleaning of the scratches Arceo Engineering, 12 sept. 2016 10

ArenNano Black Stainless  Corrosion resistance QCT > 4000 h (in progress)  Salt Spray Test > 2000 h (in progress) QUVa + humidity > 4000 h (in progress) Arceo Engineering, 12 sept. 2016 11

ArenNano Black Stainless  Chemicals and Food resistance Food stuff Food stuff Food stuff Chemicals Chemicals 24h @ 23 ° C 2h @ 23 ° C 1h @ 70 ° C 24h @ 23 ° C 2h @ 23 ° C Milk Ketchup Tea Ethanol CIF detergent Butter Mustard Coffee Acetone NaOH Tomato sauce Olive oil Acetic acid Lemon Salt water Cola  Certificate of compliance Safety of Toys EN71-3  Certificate of non migration as per EN-1186 (migration 0004-S)  Temperature resistance  1h @ 170 ° C : OK  1h in boiling water : OK Arceo Engineering, 12 sept. 2016 12

ArenNano Black Stainless  Conclusions  The ArenNano Black Stainless coating solution shows :  a pleasant aesthetic finish respecting the grinded metallic appearance  Resistance to wear and friction  Bending and deepdrawing (13% Marciniak) abilities  Resistance to food stuff and chemicals  Typical applications are :  Household goods, home appliances, kitchen decoration, indoor architecture  Effective outdoor corrosion tests allow as well outdoor applications (tests ongoing).
