This product is not recommended for use in oxygen-rich and/or pure oxygen systems and should not be selected as a sealant for chlorine or other strong oxidizing materials.

For information on the safe handling of this product, please refer to the Safety Data Sheet (SDS).

Surface Preparation

Surface preparation is important for the long-term performance of the product. The parameters can vary depending on the severity of the application, expected lifespan, and initial conditions of the substrates to be treated.

1. Remove dirt, oil, grease, etc. with a suitable cleaner.
2. Any irregularity, weld spatter or slag, and any other surface roughness, must be leveled and flattened; any recess or porosity must be filled and leveled. Any protrusion, edge or joint, must be leveled with a minimum radius of 3mm and any corner must also be rounded with the same characteristics.
3. Sandblast the entire surface to be treated with an angular grit to achieve a roughness of 50-70 microns, and a blast cleaning degree close to white metal (SIS SA 2½ /SSPC-SP 10). For immersion applications, a white metal blast cleaning degree (SIS SA 3/SSPC-SP 5) is required.
4. After sandblasting, the metal surface must be cleaned with a residue-free cleaner or acetone to remove dust and contaminants. Dry, clean compressed air can also be used to eliminate dust and contaminants. The surface must be coated before new oxidation occurs.

Method of Application

1. Film thickness for coating: 400 microns (minimum). It is recommended to apply a minimum of 2 coats to avoid micro-craters.
2. Application temperature for surface and ambient: 15-30 °C.
3. Relative humidity: <85% RH; The surface temperature must always be at least 3 °C above the dew point.
4. Spray systems

• Airless system for abrasive two-component materials with a compression ratio of at least 45:1.
• Nozzle 0.015” – 0.019”; angle 50-60°, dependent on the part to be coated.
• Nozzle pressure: 210 bar minimum. Product temperature ≥25 °C.

The second overlay coats must be applied once the product layer has gelled, but not yet cured, within the “recoating time.” If this time is exceeded, lightly abrade the surface and clean with MEK to remove residue.

Check:

• After application is completed, visually check for any untreated porosity.
• Once the coating has cured, repeat the visual inspection to confirm the absence of untreated areas, porosity, or mechanical damage.
• Check the coating thickness, especially at critical points.

Repairs

Any untreated area or porosity, or zone with insufficient thickness, that is detected must be restored or repaired by applying additional product, after light abrasion and surface cleaning.

Cleaning

Clean the equipment immediately after use with a solvent such as acetone or isopropyl alcohol. Once cured, the product can only be removed mechanically.
