Pastes

for easy assembly and dismantling

The structure of pastes corresponds in principle to that of greases. However, the share of solid lubricants is clearly higher. Thus a reliable lubricating, parting and corrosion protection effect is ensured even when used under extreme temperature and pressure conditions and aggressive media. Pastes are used at screw threaded connections as well as for pressing in pins and bolts, at gearwheels, chucks, hinges and plain bearings.

 

 Characteristics StandardDescription
 Press-fit-test Provides information on the lubricating effect of pastes at a very high pressure and low sliding speed (relevant for assembly pastes)
 Thread friction coefficient DIN 946The coefficient of sliding friction μ when tightening screws and nuts is determined on a screw test bench (relevant for screw pastes)
 Breakaway torque

 DIN 267-27

Ratio of the breakaway torque required when loosening the screwed connection to the tightening torque
 Operating temperature 

Lubrication: Oil and solid lubricants are effective
Separation: After volatising of the oil separation effect through solid lubricants

 

 

 

 

 

 

 

 

 

The range of applications of pastes depends considerably on the solid lubricants contained.
