These times are based on 130 µm DFT. Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure
Surface Preparation
General
Surfaces must be clean and dry
Employ adequate methods to remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating
Steel
For immersion service, blast clean to Sa 2½ (ISO 8501-1), for other service St 2-3 (ISO 8501-1) may be sufficient
Alternatively, ultra-high pressure water jetting to Nace No. 7 min. C Vis WJ-2. Max flash rust; C Vis WJ-2M
Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether expressed or implied

Industry standards are for substrate temperatures to be 3°C above the dew point
Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel
Special application techniques may be required above or below normal application conditions
