      About ChemLINE® 784

      ChemLINE® 784 is a high functionality, two component thermoset polymer coating. When cured, the ChemLINE® 784 high cross-link density is unlike other coatings. ChemLINE® 784 delivers significantly improved product performance and anti-corrosion resistance. ChemLINE® 784 coating is formulated with a unique polymer designed and engineered with high functionality. This bridged aromatic backbone structure, when polymerized, forms up to 784 cross-links. ChemLINE® 784 cross-links predominately through an ether (carbon-oxygen-carbon) linkage. This eliminates high concentrations of hydroxyl groups (found in epoxies) and precludes formation of ester groups (found in vinylesters) which are subject to hydrolysis and acid attack. ChemLINE® 784 can be ambient cured or lower temperature forced air cured depending on substrate and service conditions.*

      ChemLINE® 784‘s Higher Cross-Link Density Means:

      • Higher chemical resistance
      • Higher toughness
      • Higher heat resistance
      • Higher resistance to abrasion

      Provides Superior Chemical Resistance to:

      • 98% Sulfuric Acid
      • 37% Hydrochloric Acid
      • 50% Sodium Hydroxide
      • Most acids, alkalies, and solvents
      • Methanol
      • Methylene Chloride
      • Acetic Acid

      The Technology

      Epoxies, Vinylesters and ChemLINE® 784 Form 3 Dimensional Screen-Like Structures when Cured

      chemline-technology-illustration

      • 28 functionality forming up to 784 cross links
      • Majority of cross links are through Ether (C-O-C) bonds. Ether bonds are one of the strongest bonds in chemistry. Ether bonds give flexibility with chemical resistance.
      • No ester groups.
