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 4hours). 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
-Tip size – 31-33 thou (0.79-0.84mm) approximately
*Tip pressure – 3600 psi (25Mpa) approximately
*Tip angle – 30°
