Suitable Surfaces

 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.

Bare Steel:

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

Coated Surfaces:

Clean, dry and undamaged compatible primer .

Other Surfaces:

For aluminum substrates , thorough washing and sweeping with a nonmetallic blast medium is required.

Application Conditions

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.

Application Information

– 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°

Recommended Primers

-PE1003 PRIMAPOX Zinc 2K

Recommended Topcoats


Cleaning Thinner

Equipment should be cleaned immediately Auer use with Paint Thinner Colorama TH907EP.

Drying time:

Drying times are affected by air ventilation, temperature, film thickness and number of coats.
Substrate Temp.                           10° C                 25° C                  40° C
Surface Dry                                      4                       2                          1
Through Dry                                   12                      8                          6
Dry to recoat, minimum              16                      12                          8
The given data serve as guideline only. The actual drying time differs according to film thickness, ventilation, humidity and underlying paint system.

Typical paint system:

PRIMABUILD – ST 1 x 100 µ
INTUPOX 1 x 2000-5000 µ (Depending on Hp/A Value)
URELUX 1 x 50 µ


Keep the containers in a dry, cool, well ventilated space and away from source of heat and ignition. Containers must be kept tightly closed.


Handle with care. Stir well before use.
Packing Size:                                            18 L
