Sika® Permacor®-2107 HS

Hot spray epoxy coating, 100 % volume solids

Sika® Permacor®-2107 HS is a 2-pack epoxy coating with 100 % volume solids and applied with 2-pack hot-spray equipment. The coating has high physical strength, with good abrasion and impact resistance. Solvent free according to Protective Coatings Directive of German Paint Industry Association (VdL-RL 04).

  • Excellent resistance to water, sewage and the spillage of a wide range of chemicals, flammable and non-flammable liquids
  • Resistant to root damage and microbial degrade
  • Resistant to biogas and natural gases - consequently no softening of the coating when buried
  • Very good adhesion to steel surfaces
  • Particularly economic to use, owing to its single-coat application
  • Excellent long term service record

SURFACE PREPARATION

Steel:

Remove all weld spatter, then grind welds and joints in accordance with EN 14879-1.

Blast cleaning to Sa 2 ½ according to ISO 12944-4.

Free from dirt, oil and grease.

Average roughness depth RZ ≥ 50 μm.

MIXING

Application exclusively with 2-pack-hotspray airless equipment.

Stir both components separately prior to application.

Do not thin Sika® Permacor®-2107 HS!

APPLICATION

Hot spraying

  • Undiluted
  • Use special airless hot-spray equipment
  • Temperature at nozzle: + 65°C to + 70°C


Repair

  • Undiluted
  • Suitable only for the repair of small areas


Clean and prepare damaged areas by sanding or sweep blasting of areas to be coated and ensure thorough removal of dust. As soon as possible the cold mixed material should be applied by trowel.
