SURFACE PREPARATION
* Surface must be clean, dry and free of soot, grease, oil or any other
contaminant.
* To ensure good adhesion, ferrous surfaces must be sandblasted.
For optimum chemical resistance:
Sandblast to near white metal (SSPC-SP-10).
For immersion:
Sandblast to white metal (SSPC-SP-5).
MIX AND DILUTION
* Mixing ratio ready to use (volume/volume):
. 577-625: 2½ parts
. 576-092 (hardener): 1 part
* No induction time necessary.
* Pot life: 6 hours maximum.
METHOD OF APPLICATION
By spray, using either:
* conventional pneumatic
* airless
Maximum tip opening: 15 mils
Application recommendations:
* Dry film thickness:
. Sandblasted steel: 4 to 6 mils (100 to 150 microns)
Minimum 2 mils (50 microns) over blast profile.
* Apply at a minimum temperature of 10°C (50°F) and maximum
of 35°C (95°F).
* After a drying period of 72 hours, sand primer lightly before
application of topcoat.
