PRODUCT DESCRIPTION

is obtained through controlled sintering of an atomised powder of Alpha–Alumina. The special production process creates a perfectly dense and compact product with exceptional hardness, second only to diamond. This hardness makes SARCER the product with the highest duration of protection from wear. Another extraordinary characteristic of SARCER is its chemical inertness: only hydrofluoric acid is able to damage its structure. Refinement of the SARCER production techniques has allowed for the creation – without modifying the structural and technical characteristics – of pieces with smaller size suitable for creating mosaic mats: SARMOS. This technology combines ease of installation and effective protection. The reduced size of the plates guarantees excellent coverage of the surfaces, even the most complex ones, with a consequent reduction in installation times, thicknesses, weights and costs. With this technology it is possible to cover pipes and bends of non-standard sizes. The mosaic structure reduces the effects due to impact wear, limiting the damaged area to the individual tile affected.

INSTRUCTIONS FOR USE

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.
  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 any dust and contaminants; clean, dry compressed air can also be used. The surface must be coated before any new oxidation occurs.
