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

Organic VpCI’s vs. Pigment Corrosion Inhibitors 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

Organic additives vs. Conventional Pigment additives

Challenges while Using Pigments Toxicity Settling Resin Reactivity Scribe Protection

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

Additive for Coatings Water-based Additives – Flash Rust Inhibitors M-111 M-240 M-241 M-380 M-435 Water-based Additives – Long Term Corrosion Protection M-118 M-119/M-119LV M-381 Solvent Based Additives M-109 M-110 M-168 M-5365

VpCI Coatings vs. Non-VpCI Coatings Blisters, creepage Lower DFT

Traditional Alkyd

Vinyl Toluene Alkyds

Traditional Acrylic

Excellent Flash Rust Inhibition

Conclusions VpCIs coatings additives improves Scribe resistance Salt spray & Humidity resistance Contact inhibition Standard industrial coatings can be modified with VpCIs as corrosion inhibitors
