Why Aum Dacro for top coats
A topcoat is only as good as the friction number it lands on. We select and validate the topcoat to hit your torque-tension window — not just add a layer.
- Full portfolio to tune COF: PLUS® clear and black, Torquer series and PTFE-based lubricated topcoats to hold a controlled friction band with low scatter.
- You see the data, not just the part: in-house COF and salt-spray testing, with PDI, SST and friction reports delivered through our customer portal.
- Appearance and part ID: colour and black options where identification or aesthetics are specified.
- Stable multi-tightening across aluminium, cast iron, e-coat and steel counterfaces.
The differentiator isn’t the topcoat brand — it’s that we prove the friction result before your parts leave the plant.

Torquer Series
Preventing looseness / Cost reduction / Weight reduction The Torquer Series is effective in every situation
Increasing the size and number of bottles is not enough to prevent loosening.
Combined with our zinc flake basecoats, ECHOTE® WH700 reacts and creates a barrier effect that improves both the
corrosion resistance of the system and the galvanic corrosion protection with aluminum and different noble metals.
The most effective way to prevent loosening is to stabilize the coefficient of friction and exert an appropriate tightening
axial force.
01
Stable fastening axial force prevent looseness
When the friction coefficient is stable, it is possible to obtain a stable tightening axial force without any variation in all
bolts when tightening with the same tightening torque.
02
A stable friction coefficient
Applying the Torquer Series reduces the variation in the friction coefficient and makes it stable. We offer 3 types of
lineups that allow you to choose the one that suits your needs best.
03
Maximize the utilization of bolts without sacrificing performance
When the tightening torque is 20N*m, with M8 x 1.25 bolts (strength classification 6.8), only 7KN of tightening axial
force can be obtained with non-lubricated bolts. However, when Neotorquer is applied, a tightening axial force of 17KN
can be obtained
In this way the Torquer series can maximize bolt performance.
04
No more increasing the size in the number of bolts
Until now, it was necessary to increase the size and number of bolts in order to obtain the required tightening axial
force. By using the Torquer series, more tightening axial force can be obtained. As a result, it is possible to reduce the
size and number of bolts, thus reducing both the cost and the overall weight.When the tightening torque is 20N*m, with M8 x 1.25 bolts (strength classification 6.8), only 7KN of tightening axial
force can be obtained with non-lubricated bolts. However, when Neotorquer is applied, a tightening axial force of 17KN
can be obtained
