How to use
Remove dirt, oil, grease, etc. with a suitable cleaner, e.g. high pressure water cleaning system using Loctite® SF 7840TM (Loctite® Natural Blue® cleaner/degreaser).
Blast all surfaces to be coated with a sharp-edged angular grit to achieve a profile depth of 75 to 100 microns and a degree of cleanliness of Near White Metal (SIS SA 2½ / SSPC-SP 10); after blasting, clean the metal surfaces with a waterless cleaner, such as an IPA cleaner, and coat them before any oxidation or contamination occurs. Metal that has been in contact with salt solutions, such as seawater, should be grit blasted, high-pressure water blasted, and left for 24 hours to allow any salts in the metal to migrate to the surface, followed by a chloride contamination test; this procedure should be repeated until the chloride concentration on the surface is below 40 ppm.
