General properties and applications: KONTAKT  CHEMIE  Kontakt  60  is  a  contact  cleaning  oil  which  can  be  used  to  restore corroded electrical contacts. In aerosol form it is particularly suitable for service applications, it can be dispensed economically and accurately (with special spray tube). In addition to the corrosion-dissolving components, the spray contains a solvent mixture which also removes greasy or resinous residues. Problems with electrical contacts are caused in fact not just by corrosion but also by polluting gases which form coatings of low electrical conductivity on the contact surfaces ("polymers").   KONTAKT  CHEMIE  Kontakt  60  is  also  supplied  as  a  concentrate.  The  concentrate  is normally diluted with KONTAKT CHEMIE Kontakt WL and then has comparable properties with the aerosol. See also the special application instructions on page 2.

Optimum results are obtained, if dissolved dirt and corrosion products  are  then  rinsed  off  with  KONTAKT  CHEMIE  Kontakt  WL.  After  that,  KONTAKT CHEMIE Kontakt 61 is applied as a protective film. KONTAKT CHEMIE Kontakt 60 works in many cases even without after-treatment. However this increases the risk that corrosion damage will appear again after a short time. Contacts of fairly large plug connectors and robust relays can also be sprayed with KONTAKT CHEMIE Kontakt  40  to  give  them  protection  from  corrosion.  If  you  are  certain  that  a  contact  is malfunctioning  only  because  of  contamination,  resinification  etc.  and  not  due  to  corrosion, KONTAKT CHEMIE 61 can also be used directly without further pre-treatment. When very large quantities of KONTAKT CHEMIE Kontakt 60 are being consumed, the use of the concentrate may be economic. It is diluted in accordance with the instructions.   When  Kontakt  60  is  used  in  serial  production,  plastics  compatibility  should  be  tested. Particular   attention   should   be   paid   to   plastics   susceptible   to   stress-cracking   (e.g. polycarbonate and polystyrene) and parts subjected to heavy mechanical loads. Diluted solutions of KONTAKT CHEMIE Kontakt 60 and the aerosol spray contain flammable solvents. Therefore the liquids must not be sprayed onto energised equipment. The solvent must be completely evaporated before the equipment is started up again. A period of at least 15  minutes  is  to  be  allowed  for  this.  Local  conditions  may  require  a  longer  drying  time, particularly when there is an insufficient flow of fresh air to the places being treated. Further information on safety can be found in the safety datasheet. For  special  uses  it  is  also  possible  to  apply  KONTAKT  CHEMIE  Kontakt  60  concentrate undiluted.  An  injection  spray  or  an  appropriate  dispenser,  for  example,  is  suitable  for  this. The cleaning action on organic deposits (oils, greases, resin residues), however, is not so good as with the aerosol and this for a solution diluted as described in the instructions. It is advantageous, because of the high flash point, the concentrate can be used when potential sources of ignition are present.. Optimum contact cleaning in 3 phases Phase 1: Kontakt 60 dissolves corrosion layers and thereby restores metallic contact. Without phases 2 and 3 it is possible for corrosion to occur again after a certain period of time. This depends on the material and the ambient conditions. Phase 2: Kontakt WL washes away dissolved corrosion products, grease and dirt. Phase 3: Kontakt 61 forms a thin protective film which inhibits corrosion and wear.
