| Résumé : |
Increasing demand to reduce emissions of volatile organic compounds (VOC) has led the chemical and petrochemical indus-tries to consider alternatives to the solvent-borne epoxy resins used as primers and mid coats. A novel epoxy resin offers excel¬lent performance and increased productivity for asset owners and contractors. The results of a two-year field trial suggest it enables thin film, high build and application efficiencies while performing in two and three-layer zinc-rich barrier systems. |
