MODENGY 1026 anti-friction coating: new solution to extend service lifetime of the large-scale equipment

Introduction

MODENGY 1026 anti-friction solid-film coating has become one of the main developments of the Modengy Research and Production Center in the year 2024.

It combines properties and characteristics that were not possible to be realized in a cold-cured lubricating material earlier.

MODENGY 1026 anti-friction solid-film coating was created as a reply to meet one of the issues that manufacturers and operators of the large-scale equipment face: it is difficult or impossible to apply the hot-cured coatings that require heating and exposing in a kiln at + 200 °С onto the large size components. The cold-cured coating available at the market, in their turn, cannot fully meet the requirements towards the anti-corrosive properties and the service lifetime.

Knowing that, the Modengy’s chemical engineers have designed a product that gets cured at room temperature, requires no heating in a kiln, and at the same time is not inferior to the hot-cured coatings on corrosion resistance level, anti-friction properties, and service lifetime.

Properties, advantages, and application fields of MODENGY 1026

MODENGY 1026 is suspension of the anti-friction solid-film coating based on molybdenum disulfide that is supplied even in an aerosol cans (See Fig.1) for easy and convenient use in the field with no need in any spray equipment as well as in cans and pails to be applied in the indoor areas specifically equipped for painting.

As soon as it gets cured, it forms a thin 20 µm thick composite layer on the treated surfaces of the parts. This layer is a polymer matrix of the binder firmly bonded to the base that has highly dispersed molybdenum disulfide particles in its cells.

Special reinforcing fibrous structures are also added to its composition (See Fig.2), and due to this a long service lifetime, much more extended than other cold-cured materials have, is provided.

MODENGY 1026 is intended to provide efficient dry lubrication and corrosion protection for the metal-to-metal friction pairs.

The coating has high compression resistance and low shear resistance: its dry friction coefficient reaches values of several hundredths.

The uniqueness and the main feature of this material is high anticorrosive properties that are equivalent to the characteristics of the hot-cured compounds: more than 760 hours, according to the results of the accelerated tests in the neutral salt mist chamber on ISO 9227 international standard.

MODENGY 1026 advantages are the following:

• Improved tribotechnical properties
• High anticorrosive properties (MODENGY 1026 is many times superior to other materials of its class)
• Operability in dusty environment
• High load-carrying capacity
• Wide service temperatures range
• Long service lifetime
• Curing at room temperature

MODENGY 1026 is designed to extend service lifetime of sliding bearings and guideways, gears, splined and key joints, threaded connections, and other units with metal-to-metal friction pairs (See Fig.3).

This coating has passed tests and demonstrated high efficiency at the Russian manufacturers of fasteners, metalworks, automotive components, and downhole motors for well-drilling.

Also, it is successfully used in the pipeline fitting units such as locking elements (globes, disks, plugs) to reduce friction between the locking element and the saddle, to protect effectively against corrosion; threaded connections to protect against jamming at mounting and dismantling, to increase corrosion resistance; lead screws; valve and gate rods, etc.

How to apply MODENGY 1026 coating out of an aerosol can

To obtain a high-quality coating, it is necessary to act in accordance with the technological instructions.

If there are a lot of contaminations on the part surface firmly bonded to it, it is necessary to remove them with any available way, mechanical or chemical. Use MODENGY Special Cleaner-Activator for finishing surface preparation before applying the coating. It is permitted to touch the prepared surface only wearing clean gloves.

Shake thoroughly the can of MODENGY 1026 coating till you can hear sound of small metal balls tapping, and keep shaking for at least three minutes more after that.

Spray MODENGY 1026 coating to the treated surface in a thin uniform layer from the distance of 15 to 20 cm.

It is required to expose the treated part at room temperature during 10 minutes till it gets mat, dry, and tack-free

After that apply the second layer if necessary.

The coating cures completely during at least 180 minutes at +20 °С. It is possible to accelerate the process of curing by heating or blowing with hot air.

MODENGY 1026 coating unites in it the best properties of anti-friction solid-film materials: long service lifetime, anti-friction and anti-corrosion properties as well as possibility of curing at room temperature.

Application of this product is promising in all industries to improve efficiency and reliability of operating the equipment.
