RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES
Atmospheric exposure conditions
-
Steel; blast cleaned to ISO-Sa21⁄2, for excellent corrosion protection
-
Steel; blast cleaned to ISO-Sa2, blasting profile 40 – 70 μm (1.6 – 2.8 mils) or power tool cleaned to ISO-St2 for good
corrosion protection
-
Shop primed steel; pretreated to SPSS-Pt3
-
Coated steel; hydrojetted to VIS WJ2/3L
-
Existing sound coating systems; sufficiently roughened, dry and cleaned
Immersion in water with cathodic protection
-
Steel; blast cleaned to ISO-Sa21⁄2, blasting profile 40 – 70 μm (1.6 – 2.8 mils)
-
Steel with approved zinc silicate shop primer; sweep blasted to SPSS-Ss or power tool cleaned to SPSS-Pt3
-
First coat SIGMACOVER 630 aluminum
Substrate temperature
-
Substrate temperature during application and curing should be above 10°C (50°F)
-
Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
INSTRUCTIONS FOR USE
Mixing ratio by volume: base to hardener 83:17
-
-
The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
-
Adding too much thinner results in reduced sag resistance and slower cure
-
Thinner should be added after mixing the components
Induction time
None
Pot life
2 hours at 20°C (68°F)
