Solvent-free anti-abrasion epoxy coating

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 oxidising materials.

For information on the safe handling of this product, consult 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 service life, and initial conditions of the substrates to be treated.

1. Remove any dirt, oil, grease etc. with a suitable detergent.
2. Any irregularities, weld splashes or residue, and any other surface roughness must be levelled and ground smooth; any depressions or porosity must be filled and ground smooth. All protrusions, edges or joints must be levelled to a minimum radius of 3 mm and all corners must also be rounded to the same specifications.
3. Blast the entire surface to be treated with angular grit until you achieve roughness of 50-70 microns, and near-white metal blast cleaning level (SIS SA 2½ /SSPC-SP 10). For immersion applications, a white metal blast cleaning (SIS SA 3/SSPC-SP 5) level is required.
4. After abrasive blasting, the metal surface must be cleaned with a cleaner which does not leave residue, or with acetone, to remove dust and contaminants. Clean, dry compressed air can also be used to remove dust and contaminants. The surface must be coated before any new oxidation occurs.

Method of Application:

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

• Airless sprayer for abrasive two-pack products with compression ratio of at least 45:1.
• Nozzle: 0.015” – 0.019”; fan 50-60°, depending on the area to be coated.
• Nozzle pressure: 210 bar minimum. Product temperature ≥25 °C.

Subsequent coats must be applied once the product layer has gelled but not cured, within the “overcoating time”. If this time is exceeded, lightly abrade the surface and clean it with MEK to remove residues.

Check:

• Perform a visual check as soon as application is complete to ensure there is no 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 in critical areas.

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.
