GENERAL INFORMATION

This product is not recommended for use in systems rich in oxygen and/or pure oxygen and must not be selected as a sealant for chlorine or other strong oxidising agents.

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 may vary depending on the severity of the application, durability expectations and initial conditions of the substrate 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 micron, 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 a solvent, 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. Mix the two components, suitably weighed out in the quantities specified by the mixing ratio, for around 3 min.
2. Film thickness 1mm.
3. Application temperature (surface and ambient): 15-30 °C.
4. Relative humidity: <85 %; The surface temperature must always be at least 3 °C above the dew point.
5. All untreated areas or areas with limited thickness must be restored by applying further product before installing the covering to be adhered

Cleaning

Clean tools immediately after use with a solvent such as acetone or isopropyl alcohol. Once hardened, the product can only be removed via mechanical means.
