Prior to application of a compatible primer, the steel substrate must be abrasive blast cleaned in accordance with standard ISO 8501-1:1988. Cleanliness Sa 2.5. Roughness 50 to 85 microns Ry5.
Coating should occur before degradation of the surface takes place (normally within 4 hours). If oxidation takes place, the steel must be re-prepared. The surface must be dry and free of dust, salts, grease and any other contaminants immediately before coating.
Cleanliness: Blast – cleaning to Sa2 1/2 (ISO-8501-1:2007). Power tool cleaning to min. St2 (ISO 8501- 1:2007) may be acceptable, subject to exposure conditions.
Shop primed Steel:
Clean, dry and undamaged approved shop primer
Clean, dry and undamaged compatible primer .
For aluminum substrates , thorough washing and sweeping with a nonmetallic blast medium is required.
Substrate temperature can be 15°C or above for application and during cure and a minimum of 5°C above the dew point. Adequate dry air ventilation is recommended for optimum drying.
– Normally applied by airless spray
-Stir thoroughly before use until product is homogeneous
-Pump ratio: minimum 45:1
1 Tip size – 31-33 thou (0.79-0.84mm) approximately
2 Tip pressure – 3600 psi (25Mpa) approximately
3 Tip angle – 30°
