Solid lubricant coating MS 2020 VMPAUTO 20g

Solid lubricant coating MS 2020 VMPAUTO 20g

The composition of MS 2020 is a suspension of molybdenum disulfide in a polymer solution and is intended for obtaining an anti-friction solid lubricant coating cured at room temperature.

Application
Surface preparation
The surface must be thoroughly cleaned, degreased with solvent 646 or nefras C2-80/120, then dried. Drying is recommended in an oven or oven at a temperature of about +50°C for 30 minutes.

Contamination of the prepared surface with water, oil, dust, other substances that can reduce the adhesion of the composition to the substrate is not allowed, contact with hands is not allowed. The interval between surface preparation and application of MS 2020 must not exceed 60 minutes.

The durability of the coating depends on the surface roughness, the optimal value of which is Ra = 1.6-3.2 µm. Preliminary sandblasting and chemical processing of surfaces are recommended.

Application
Before use, thoroughly mix the composition of MS 2020 with a clean stick or stirrer for at least 10 minutes (color heterogeneity is allowed during mixing). At the end of mixing, the composition should be a dark gray colored mass, while no sediment should remain on the bottom and on the walls of the container. If necessary, dilution of MS 2020 with technical isopropyl alcohol is allowed. Application of the composition is recommended at a temperature of 20±10º and relative air humidity of not more than 80% using one of the following methods:
Spraying Is the most preferred, because it allows you to control the thickness and uniformity of the applied layer. Provides maximum adhesion and wear resistance of the coating.

Dipping Not recommended for applications where control of application thickness is required.

Application by brush Not recommended for applications where control of application thickness is required. The composition of MS 2020 is applied in 1-2 layers. The recommended thickness of the dry coating layer is 7-15 microns. If necessary, the second layer is applied after drying the previous one in air at room temperature until dull (20 minutes). The surface should be covered as evenly as possible.

Curing
The part with the applied composition is dried in air at a temperature of 15÷25° for 2-3 hours, after which it can be put into operation.

It is recommended to control the thickness of the coating with a thickness gauge for paints and varnishes. If the coating thickness is greater than the required one, it is allowed to finish the specified thickness by lapping the mating part. Cleaning with abrasive tools is prohibited.

Quality control
By visual inspection, the coating should be matt, solid and dark gray. Bubbles, streaks, delaminations, the presence of foreign inclusions, craters, gloss, mechanical damage are not allowed.
