Product Information
ChemLine® 784/32
A coating with superior chemical resistance and high temperature resistance.
Description
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. ChemLine® 784/32 coating is formulated with a unique polymer designed and engineered with
28 functional groups per molecule. This bridged aromatic backbone structure, when polymerized, translates into 784 crosslinks.
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.
- Paper & Pulp - Digesters, black liquor tanks, bleaching, etc.

The Technology; Epoxies, Vinylesters and ChemLine® 784/32
Form 3 Dimensional Screen-Like Structures when Cured
ChemLine 784/32
- 28 functionality forming 784 crosslinks
- Very small opening between groups
- Majority of crosslinks 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 hydroxyl or ester groups which are subject to hydrolysis and chemical attack.
