Suitable Surfaces :

• Steel and non-ferrous metals properly blast cleaned to SIS-Sa 2 1/2 minimum
• Substrates must be free of contamination, dust, and efflorescence
• Previously gloss painted surfaces should be thoroughly abraded or sand blasted
  before application.

Bare Steel :

Cleanliness: Blast – cleaning to Sa2 1/2 (ISO-8501-1:2007). Power tool cleaning to min. St2 (ISO8501-1:2007) 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. For aluminum substrates, thorough washing and sweeping with a nonmetallic blast medium is required.

Application Conditions :

Substrate temperature should be 10°C or above for application and during cure, and a minimum of 3°C above the dew point. Adequate dry air ventilation is recommended for optimum drying.

Application Information :

Thinning should only take place after the material has been thoroughly mixed.

Brush and Roller :

Thin if required with 0-5% COLORAMA Thinner 906 or 921.

Conventional Air Spraying :

• Thin with 5-15% COLORAMA Thinner 906 or 921, as required.
• Tip size – 2.0 mm.
• Tip pressure – 60 psi (0. 4Mpa) approximately.

Airless Spraying :

• Thin with 5-15% COLORAMA Thinner 906 or 921, as required.
• Tip size – 2.0 mm.
• Tip pressure – 60 psi (0. 4Mpa) approximately.

Airless Spraying :

• Thin with 0-10% COLORAMA Thinner 906 or 921, as required.
• Tip size – 13 thou (0.33mm) approximately.
• Tip pressure – 1700 psi (12Mpa) approximately.

Cleaning Thinner :

Equipment should be cleaned immediately after use with COLORAMA Thinner 906 or 921.

Drying time :

Drying times are affected by air ventilation, temperature, film thickness and number of coats.
Substrate Temp.                                              10° C                      25° C                            40° C
