Features & Benefits

• 2-component polyurethane paint cured with aliphatic isocyanates
• Good gloss retention and colour stability
• Contains zinc phosphate
• Recommended as a high-build solution for protecting steel structures, in compliance with VOC regulations
• May be specified as a one-coat direct-to-metal system in corrosive environments classified as C2 and C3
• Can also be used as an undercoated intermediate coat or topcoat within the system
• Service temperature - Maximum, dry exposure only: 120°C
• Complies with the European Fire Standard EN 13501-1, reaction to fire classification, when used as part of a predefined paint system. B-s1, d0

Preparation

• Cleanliness:
  • Remove oil, grease and other contaminants by suitable detergent cleaning
  • Remove salts, detergents and other contaminants by high pressure fresh water cleaning
• New build:
  • Abrasive blasting to min. Sa 2½ (ISO 8501-1) / SP 10 (SSPC)
  • Remove dust, blast media and loose materials
  • All damage of shopprimer and contamination from storage and fabrication should be thoroughly mechanically/chemically cleaned prior to final painting
• Maintenance and Repair:
  • Remove dust, blast media and loose materials
  • Feather edges to sound surrounding coating
  • Flash rust degree of maximum FR M (ISO 8501-4)
  • Minor areas may be hand or power tool cleaned instead of abrasive blasting
  • Spot abrasive blasting to min. PSa 2 (ISO 8501-2) / SP 6 (SSPC)
  • Water jetting to min. Wa 2 (ISO 8501-4)
• Roughness - Surface profile Medium (S) (ISO 8503-2)

Application

• Mixing ratio - Base 55759 : Curing Agent 97050 (9.1 : 0.9 by volume). Stir well before use
• Thinner/Cleaner: Hempel's Thinner 08080
• Pot life: 2 hours @ 20°C
• Apply with brush or airless spray (Nozzle pressure: 200-250 bar [2900 psi] Nozzle orifice: 0.015-0.021")
• Dry film thickness: 50 - 160 micron (100 recommended)
• Wet film thickness: 75 - 250 micron (150 recommended)
• Coverage: 4.1m²/L - 13m²/L (6.5m²/L recommended)
• To avoid condensation, apply on a clean and dry surface with a temperature that is at least 3°C above the dew point
• Surface temperature must be above -10°C during application and curing
• Beware of ice on the surface at low temperatures
• The film formation may be adversely affected by light rain, high humidity and/or condensation during application and the following interval after application: “8 hours, 20°C”
• Relative Humidity:
  • Relative humidity must be below 85% during curing
  • Relative humidity must be below 85% during application
• Touch dry in 60 minutes @ 20°C, hard dry in 120 minutes @ 20°C

Spray data are indicative and subject to adjustment. Pressure is for a material temperature of 20°C.

For best performance, avoid excessive film thickness. Product may be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate, drying and curing time and overcoating interval.

To obtain the drying time stated, it is important to maintain sufficient ventilation during application, drying and curing. Condensation on the freshly applied coating should be avoided.
