Application of MODENGY 1031 friction coating optimizes the mounting process of the critical metal structures. Applying this product as part of the mass production of bolt sets solves an important task: it prevents the washers from rotating in process of tightening the threaded connection.
The issue is that the turning fastener is carrying the washer with it, and the latter fails to latch relative to the supporting surface. And this results in changing torque coefficient, decreasing tightening efficiency of the connection, and operational reliability of the metal structure in general.
Use of the coating with friction properties completely eliminates risk of washer rotation relative to the substrate. The washer remains fixed at tightening while the bolt head keeps turning relative to it, so that contact area between the washer and the substrate is much larger than the one between the washer and the bolt head or the nut. Due to this, torque coefficient remains stable (it is calculated taking into account application of the friction coating, and other features of the threaded connections), while pre-tightening force gets predictable and controllable.
An important advantage of such approach is no need in inserting any corrective actions in the bolt set construction: geometry of the unit does not change, the stage of applying the friction coating is implemented into existing processing procedures of the enterprises. The friction coating also has good adhesion to the zinc-flake layer, and is effectively used in combination with it.
Applying MODENGY 1031 is done by the methods of spraying out or by dipping with centrifuging: the optimal way is selected taking into account the features of the processing procedure at a certain production. Also, it is possible to choose suitable polymerization mode: at +150 °С during 40 minutes since the part gets heated, or at +200 °С during 30 minutes.
Implementation of the friction coating into mass making of fasteners is confirmation of high quality and efficiency of this material in the matters related to mounting optimization, improving operational reliability of the bolt sets, providing their compliance with the operational performances declared by the manufacturer.
