ڤيتوتوب ام سي 361

All surfaces must be structurally sound, clean, and completely dry prior to application. Any traces of old paint, dust, grease, oil, mold, salts, or other surface contaminants must be thoroughly removed. 

Mechanical preparation methods, such as grinding or shot blasting, are recommended to achieve a clean, roughened, and sound substrate, free from laitance, release agents, and surface protrusions. 

The surface moisture content shall not exceed 8%, and the substrate pH must be no greater than 9. During both preparation and application, the substrate temperature must not fall below 10°C.

Ensure the substrate is fully dry and prepared prior to priming. For enhanced adhesion on porous or rough surfaces, an appropriate MMA-based primer may be applied depending on site conditions. Allow the primer to cure before proceeding with the application of Vetotop MC361. Do not apply on wet or damp surfaces.

Vetotop MC361 is supplied as a two-component system comprising Part A (base) and Part B (hardener). Before mixing, stir Part A thoroughly using a low-speed mechanical mixer (300–400 rpm) to achieve a consistent and uniform base. Add the full amount of Part B into Part A and mix immediately and continuously until a uniform blend and consistent color are obtained.

Ensure complete and proper mixing, as inadequate blending can compromise product performance. Adhere strictly to the specified mixing ratio. The mixed material has a limited pot life of 10–12 minutes at 20°C and should be applied without delay to maintain workability and prevent wastage. Avoid over-mixing to reduce the risk of air entrapment.

Vetotop MC361 shall be applied only under controlled environmental conditions, ensuring that the substrate temperature is not less than 10°C and the relative humidity does not exceed 70%. 

The material may be applied using a squeegee, trowel, roller, or approved mechanical equipment, depending on the system type. For anti-skid systems, the first coat should be applied at a thickness of 1000 μm using a squeegee or trowel, followed immediately by broadcasting silica sand aggregate uniformly onto the wet surface using the dropon method. Once fully dry, any excess aggregate must be removed, and a second coat should be applied at 500 μm using a roller. After complete curing, a clear top coat shall be applied at 100 μm dry film thickness (DFT). 

For smooth finish systems, a single coat is applied at a thickness of 1–3 mm using a squeegee or trowel, followed by the application of a clear top coat at 100 μm DFT after curing. 

In road marking applications, for plain line markings, one coat is applied using a roller, drop box, hand-pushed, or extrusion machine, with glass beads added to enhance reflectivity as required. For Spotflex, textured, or profile applications, the material should be applied using extrusion-type or handpushed machines, with the option of adding glass beads. Upon full curing, a clear top coat may be applied where necessary. Vetotop MC361 is supplied ready to use and should not be thinned under any circumstances.

Vetotop MC361 exhibits a fast-curing profile, allowing for rapid installation and return to service. At a standard temperature of 20°C, the material has a pot life of approximately 10 to 12 minutes. The applied topcoat typically cures and becomes foot-trafficable within 60 minutes. Recoating can be carried out after 60 to 90 minutes, depending on ambient conditions. Adequate ventilation must be ensured throughout the curing process, and the surface should be protected from dust, moisture, and mechanical disturbance until fully cured. Higher temperatures will accelerate the curing process, while lower temperatures may extend the curing and recoat times.

All tools should be cleaned with Vetonit Solvent XX400 immediately after use. Hardened material can only be removed mechanically.
