Surface Preparation

High pressure fresh water wash or fresh water wash, as appropriate, and remove all oil or grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning. All surfaces to be coated should be clean, dry and free from contamination.

Steel surface should be prepared to Sa2.5(GB/T 8923-1988), using automatic blasting/spraying equipment.

Steel grit or a mixture of steel grit of particle size 0.6-1.0mm and steel shot of particles size 0.6-1.4mm are normally used to give a appropriate coarseness.

Apply 725-E47 before oxidation occurs. If oxidation has occurred, the entire oxidized area should be reblasted to the standard specified above.

Limitations

Drying time will depend on the substrate temperature and ventilation. If the relative humidity is below 50%, cure will be retarded.7

725-E47 is not recommended for use as touch-up primer after fabrication.

Avoiding absorb the solvent steam and paint steam for long time. Skin and eyes must avoid contacting the paint. Pay attention to ventilate and fireproof when applying.
