ChemLine® 784/32


ChemLine® 784/32 is a high functionality, two component thermoset polymer coating. When cured, the ChemLine® 784/32 high cross-link density is unlike other coatings. ChemLine® 784/32 delivers significantly improved product performance and anti-corrosion resistance.


Product Description

ChemLine® 784/32 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® 784/32 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® 784/32 can be ambient cured or low temperature forced air cured depending on substrate and service conditions.*

ChemLine® 784/32‘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

Industry Applications

  • Chemical Processing – Tanks, vessels, hazardous waste, secondary containment, chemical plant floors, etc.

The Technology; Epoxies, Vinylesters and ChemLine® 784/32 Form 3 Dimensional Screen-Like Structures when Cured

ChemLine 784/32

  • High 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.
