Application Guide:
Surface preparation:
The surface should be clean, free of contamination, oil, grease, dust, rust, paints, moisture . . .
Blast the steel surface to SA2.
In harsh situation and immersion it’s recommended to blast to SA2 ½ remove the dust remains from blast.
Ambient condition:
While application, ambient temperature should be between 10 to 50ºc.
Application:
Mix A and B component with the certain mixing ratio, by an agitator.
For diluting the paint, use epoxy thinner T-950.
The paint can be applied by ordinary sprays or airless sprays.
Small unpainted parts and defects can be coated by brush. Ensure of clean the tools by T-950.
Storage:
12 months in tight container and protect from direct sun light.
