Pastes for easy assembly and dismantling

The structure of pastes basically corresponds to that of greases. However, the share of solid lubricants is notably higher. This ensures reliable lubricating, separating and corrosion protection effects also when used under extreme temperature and pressure conditions and aggressive media. Pastes are used at screwed connections as well as when pressing in pins and bolts and furthermore at gearwheels.

Characteristics of pastes

 Characteristic  Standard  Description
Press-fit test   Provides information about the lubricating effect of pastes at very high pressure and low sliding speed (relevant for assembly pastes)
Thread friction coefficient  DIN EN ISO 16047 The friction coefficient μ when screws and nuts are tightened is determined on a screw test bench (relevant for screw pastes)
 Breakaway torque

 DIN 267-27

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

Lubrication: Oil and solid lubricants are effective
Separation: After the oil has evaporated, separating effect through solid lubricants

Structure of pastes

The structure of high-performance pastes is similar to that of greases. The main difference is the high portion of solid component that is typical of both assembly pastes (lubrication effect only) as well as for screw pastes (lubrication and separation effect).

Fields of applications of pastes

The field of application of pastes is determined to a great extent by the solid lubricant contained.

Solid lubricant Maximum operating temperature [°C]  Field of application
 PTFE  < 300 Mounting, medium influence

 MoS2

 < 450 Montage, Aufpressvorgänge
 aluminium  < 1100 High-temperature screwed connections
 Copper  < 1100 High-temperature screwed connections, “Anti-Seize” paste, el. conductivity
“Oxide” ceramics  < 1400 Extreme-temperature screwed connections, stainless steel screwed connections
