SwiSS-­‐9®  is  a  transparent,  Teflon-­‐like  and  easy-­‐to-­‐clean  coating    

PRODUCT  DESCRIPTION  SwiSS-­‐9®   surface   treatment   is   a   two   component   liquid   solution   that   once   deposited   atop   suitable   surfaces   produces   a  protective  and  particles  and  liquids  repelling  coating.  Swiss-­‐9®  bonds  chemically  with:  

• Glass  • Ceramic  • Metal  

• Stone  • Wood  • Textile  

or  any  other  oxide  rich  surface  and  creates  a  durable  ultrathin  layer.  The  technology  is  based  on  silane  chemistry  and  was  researched  and  developed  by  scientists  Dr.  E.  Balic  and  Dr.  R.  Ghisleni  while  at  Advanced  Materials  Processing  Laboratory,  EMPA-­‐Thun.  It  is  proudly  manufactured  by  SwiSS-­‐9,  GmbH  in  Nidau,  Switzerland,  an  “EMPA  Spin-­‐off  company.”  

PROPERTIES  OF  THE  COATED  SURFACE  • Water  and  oil  repellent  Hydrophobicity  (glass):  Static  Contact  Angle  101˚  Tilt  Angle  17˚    • Anti-­‐microbial  • Anti-­‐reflective  • Anti-­‐fingerprint    • Anti-­‐icing    • Anti-­‐fog  • Anti-­‐graffiti    

• Particles  (dirt,  sand,  mineral  deposits,  vehicular  emissions  etc.)  repellent  

SwiSS-­‐9®  decreases  lime  deposition  more  than  competition  does!  SwiSS-­‐9®  decreases  sand  deposits  nearly  3X  compared  to  uncoated  glass!  SwiSS-­‐9®  film  also  increases  the  amount  of  transmitted  light/solar  energy  through  a  typical  glass  substrate  by  2-­‐3%

APPLICATION  METHODS                                                                                                STORAGE  AND  APPLICATION  INFO  

 

Consumer  application  • DIY  kit:  100%  consumer  safe    

           Factory  application  • Spraying  and  orbital  polishing  

(http://youtu.be/VjX5xGfP0qI)  (efficiency:  2m2  coated  in  3.5’)  

• Industrial  roll-­‐to-­‐roll  deposition  system  (deposition  efficiency  as  per  customer’s  requirements)  

CURING  TIME  AND  APPLICATION  CONDITIONS  Deposition  &  curing  time  is  1-­‐2  minutes  in  typical  European  outdoor  conditions  or  on  factory  floors  per  meter  squared.  The  surface  needs  to  be  dirt  and  particles  clean  prior  to  deposition  of  the  coating.    CONSUMPTION  Empirical   efficiency   on   glass   is   1   liter   for   125   m2.   As   it   is   a   two-­‐component  solution,   to  cover  125  m2,  you  will  need  1   liter  of   the   first  layer  (primer)  and  1  liter  of  the  second  layer  (functionalization).  PRODUCT  STORAGE  Container   must   be   closed   immediately   after   use   to   avoid   moisture  contamination.  Shelf-­‐life  is  12  months,  out  of  sunlight  and  at  25C.      FILM  MAINTENANCE  AND  DURABILITY      MAINTENANCE  The  resulting  film  is  resistant  against  typical  household  cleaning  agents.  Extended   exposures   to   strong   acids/bases   (industrial   grade)   reaching  continuous  time  durations  of  several  tens  of  minutes  can  affect  the  film.    DURABILITY  Without  any  care:  several  years.
