Cortec VpCI Additives for Coatings
• Synergistic blend of Organic VpCI with– Liquid organic contact corrosion inhibitors
– Traditional pigment technology
• Additives for both water based and solvent based coatings
• Environmentally friendly VpCI corrosion inhibitor technology
![Page 6: Cortec High Performance Additives Angel Green & Eric Uutala Cortec Corporation](https://reader030.vdocuments.mx/reader030/viewer/2022032612/56649ebe5503460f94bc8273/html5/thumbnails/6.jpg)
Organic VpCI’s vs. Pigment Corrosion Inhibitors
• VpCI’s
• Attach themselves to metal surfaces and prevent initiation of corrosion
• Fill in void spaces as they are smaller and plentiful
• Pigment
• Acts as sacrificial layer
• Large particles that leave gaps is where corrosion can occur

Challenges while Using Pigments
• Toxicity
• Settling
• Resin Reactivity
• Scribe Protection
![Page 9: Cortec High Performance Additives Angel Green & Eric Uutala Cortec Corporation](https://reader030.vdocuments.mx/reader030/viewer/2022032612/56649ebe5503460f94bc8273/html5/thumbnails/9.jpg)
Typical Toxicity Comparison
• LD50 (Lethal Dose)
– Table Salt = 3100 mg/Kg of rat– Nitrites = 86 mg/Kg of rat– Chromates = 150 mg/Kg of rat– VpCI 309 P = 2800 mg/Kg of rat

Vapor phase Corrosion Inhibitors-VpCIs
• Organic compounds– Environmentally Friendly– Low Toxicity
• VpCIs Migrate
• VpCIs are self healing
