A shock absorber is set into automotive machinery for the purpose of damping and extinguishing jerks and shocks of the car suspension, wheels, and body by means of transforming oscillating motions into thermal energy.
The support of the device is the rod on part of which is connected with the body elements while the other one is done with the piston.
The rod performs motions relative to the guideway. The polymer bushings are set between these parts that are intended to make elements sliding easier.
Because of high friction in the guideways bushing unit, the rods themselves get worn prematurely, and require replacement. The shock absorber elements damaging causes appearance of unwanted sounds while vehicle moving along the roughs, worse ability to control the car, drifting away while braking, uneven tire wear.
To extend service lifetime of the parts, and the shock absorber in general, the producers use MODENGY 1014 anti-friction solid-film coating based on polytetrafluorethylene and molybdenum disulfide.
It forms a resistant layer on the rod surface that reduces friction while elements moving, provides corrosion protection for the metal parts, improves smoothness of their movement.
This coating is applied onto the preliminary prepared surface of the rods by the standard painting methods, and get polymerized at heating in a kiln up to +200 °С within 40 minutes.
The layer of the product requires no renewing for the entire period of the shock absorber functioning, due to which long trouble-free operating of the device with no need in maintaining is provided.
Use of the anti-friction solid-film coating on the rods enables to extend operational lifetime of the car shock absorbers, to improve smoothness of the parts going.
MODENGY 1014 effectively replaces electroplating coating of the rods that is inclined to destruction in the moist environment.
