Systems and Compatibility: 

Consult your Sunrui Representative for the systems best suited for the surfaces to be protected.

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.

Newbuilding:

Remove weld spatter and smooth weld seams and sharp edges. The surfaces should be blast cleaned to Sa2.5 GB/T 8923.1-2011 .The weld seams areas could be cleaned to St3GB/T 8923.1-2011using power tool.

Apply 725-H44-61 before oxidation occurs. If oxidation has occurred, the entire oxidized area should be reblasted to the standard specified above.

Repair/On Board Maintenance:

The areas to be repaired should be cleaned to PSt3 GB/T 8923.2-2008 by mechanical method or higher level of surface prepared to PSa2.5 GB/T 8923.2- 2008 by abrasive blasting. Abrade the area immediately surrounding.

Limitations:

  • This product will not cure adequately below -10℃.For maximum performance the repair to provide a key for subsequent coating application. Overlap areas should be kept to a minimum. ambient curing temperature should be above -5℃.
  • Apply in good weather. Temperature of the surface to be coated must be least3℃above the dew point when the humidity is lower than 85%.
  • The dry time and overcoating interval may change according to the environmentfactors.
  • Avoiding absorb the solvent steam and paint steam for long time. Skin and eyesmust avoid contacting the paint. Pay attention to ventilate and fireproof when applying.
