• 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/T8923-1988),using antomatic blasting/spraying equipment.
• Steel grit or a mixture of steel grit of particle size 0.6-0.1mm and steel 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 specificed above
• Drying time will depend on the substrate temperature and ventilation. If the relative humidity is below 50%,cure will be retarded.
• 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.
