  1. Fast Curing Anticorrosion Primers For Steel Protection Dr Jean-Luc Dallons – Cardolite Corporation Presented at a meeting of the Thermoset Resin Formulators Association at the Hyatt Regency Montreal, September 11 through 12, 2006

  2. Content • Introduction • Technology • Anticorrosion • Fast and Low Temperature Curing • Surface Tolerance • Overcoating • Low VOC • Conclusions

  3. Steel is the ideal material for building structures but it has a major drawback : It rusts

  4. Approvals : ISO 12944 (Anti-corrosion) ISO 20340 (Offshore) Epoxy 2K medium coat 100-150 µm PU 2K top coat 50-80 µm Epoxy 2K Zn rich 50-80 µm Technology

  5. Industry Needs • Provide guarantee (anticorrosion) • Fast Curing • Low Temperature Curing (all year) • Surface Tolerance • Overcoat Window • Low VOC Phenalkamine Curing Agents

  6. Cardol Anacardic acid Cardanol 2-methyl cardol CNSL Composition

  7. Cardanol CNSL Phenalkamines Phenalkamines Process Cardanol Cardanol CNSL CNSL Phenalkamines Phenalkamines

  8. Cardanol Properties Reactivity Enhancement Adhesion Chemical Resistance Anticorrosion Flexibility
