Recommended Loading Levels

• Recommended loading levels range from 2-5% based on total formula weight in many water based systems.
• Recommended loading levels range from 3-7% based on total formula weight in traditional solvent based coatings.

Applications

• Epoxies
• Latex
• Alkyds (high solids and traditional)
• PVDC
• Catalyzed Baking Systems
• High Acid Value Resins
• WR Alkyds
• Water reducible alkyds
• Vinylidene chloride latexes.
• The fine particle size and low oil absorption of HALOX® SZP-395 makes it the pigment of choice in thin film applications (<1 mil or 25 microns).

Factors to Consider while Creating Coatings Solutions

• Combine the inhibitors utilize synergy of multiple mechanisms to achieve desired performance.
  • Inorganic/Flash Rust
  • Inorganic/Inorganic
  • Inorganic/Organic
• Optimize Solubility of the inhibitor. Synergize short term and long term corrosion inhibitors based on their solubility.
• Inhibitor Concentration avoid direct weight to weight replacements. Beneficial to optimize usage level.
• Substrate specific corrosion inhibitor selection can be substrate dependent.
