TECHNICAL DOCUMENTS
Use and Application
AREAS OF USE
Priming of steel exposed to water, seawater, chemicals and abrasion; newbuilding and ship repair; underwater hull surfaces and areas requiring high corrosion resistance.
SURFACE PREPARATION AND APPLICATION
Blast steel to ISO 8501-1 Sa 2½ (roughness 40–75 µm) and remove salts, grease and dust. St 3 power-tool cleaning may be used for local repairs. Keep the zinc-rich component in suspension by continuous stirring; apply by airless spray. Steel surface temperature must be at least 3 °C above the dew point and relative humidity below 85%. Use the mixture within its pot life.
SUITABLE SHIP AREAS
→ Offshore and Port Structures
Technical data are average values at 20 °C and 65% relative humidity. Coverage varies with surface roughness, application method and film thickness. Consult the Gen Boya technical team for project-specific paint specifications and system design.
