WATERBORNE WHITE DTM based on CARBOSET CR765 WITH ASCONIUM-143

This formulation is for a waterborne white direct-to-metal (DTM) paint designed for long-term protection, particularly for cold-rolled steel, with excellent salt-spray performance. Here's a breakdown:

• Description: The paint aims to provide long-term protection for cold-rolled steel, specifically designed for use as a direct-to-metal (DTM) coating. It is formulated to withstand salt-spray conditions for 500 hours.
• Components:
  1. DEIONIZED WATER: Serves as the main solvent.
  2. Disperbyk 154: Dispersing agent supplied by BYK.
  3. BYK 024: Defoamer from BYK Chemie.
  4. DPM: Co-solvent provided by Dow Chemicals.
  5. TAFIGEL PUR85: Thickener from MÜNZIG.
  6. KRONOS 2190: Titanium dioxide (TiO2) supplied by KRONOS.
  7. AMP90: Neutralizer from ANGUS.
  8. ASCONIUM-143: Anticorrosion additive from ASCOTEC.
  9. CARBOSET CR765: Binder from LUBRIZOL.
  10. DEIONIZED WATER: Additional solvent.
  11. DPM: Co-solvent from Dow Chemicals.
  12. TAFIGEL PUR 85: Thickener from MÜNZIG.
  13. TAFIGEL PUR 64: Additional thickener from MÜNZIG.
  14. ASCOTRAN-H10: Flash-rust inhibitor from ASCOTEC.
