KONTAKT 60
Contact maintenance : cleaning
 Works through a chemical reaction
 K 60 will convert the corrosion products, oxides,
sulphides, ... into soluble components
 Without damaging the base contact metal
 Restores metal-metal contact and the contact resistance
 Directions : for optimum results, flush away soluble
components with K WL, protect contact with K 61
18
KONTAKT WL
Contact Maintenance - rinsing
 After the cleaning with K60, the residues should be
rinsed away
(K 60 oil + dissolved copper oxides can become sticky)
 After that we have a bare metal, which will corrode even
more rapidly
19
KONTAKT 61
Contact Maintenance – protection, lubrication
 After cleaning with K WL, apply K 61
 Protects and lubricates the metal surface
 Leaves a thin film, with very good electric properties
 New contact also has to be protected and lubricated
20
KONTAKT 40
Contact Maintenance – protection, lubrication
 Used when main purpose is corrosion protection
 Lubrication is a little better then K 61
 Leaves a thin film with moderate electric properties
 Can be used with high voltage contacts
 K 40, multifunctional :
+ water displacement, penetrating oil
21
KONTAKT GOLD 2000
Contact Maintenance –protection, lubrication
 A high grade synthetic oil, with good anti-corrosion & very
good lubrication properties
 Prevents wear, high pressure absorption
 For soft metals : gold, silver, palladium plated contacts
 Leaves a very thin film, with excellent electric properties
 Even very small contacts can be treated

CORROSION PROTECTION - oils
Fluid 101, Kontakt 61, Vaseline 701, Kontakt 40
 Good adhesive power of the film, chemical stability
 Fl 101 : short term protection (thin film),
+ water displacement properties, restore water-damaged
equipment
 V 701 : a thick white paraffinum oil, chemical properties
and electrical properties : idem K 61, better protection
due to the thick layer.
Also used as a universal lubricant for sensitive materials

LUBRICATION - oils
Kontakt 61, Vaseline 701, Kontakt 40, Gold 2001, Lub Oil 88
 All mineral oils : lubricating is determined by good
adhesion of the film.
Surface active additives are added to improve adhesion
and chemical stability towards materials and environment
 V 701 : a universal thick lubricant for sensitive materials
also a good protector of rubber materials
 Lub 88 : very good lubricant, does not resinify : used as a
lubricant of precision mechanisms in electro-mechanics

lubrication of different materials : plastic, metal, wood,
isolation of electric cables, prevent leaking currents,
also used as a mould release agent for plastics

an ideal lubricant for slow moving parts.
To improve the adhesion : a small amount of resin has
been added to keep the powder in place.
