ChemLINE® 784 High Solids

A Coating Applied with Plural Component Equipment

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

ChemLINE® Coating Success Story

WHO: Matlack Leasing is a leading North American lessor of OTR tank trailers and tank containers serving tank operators, motor carriers, manufacturers, and chemical, petrochemical, agricultural, and environmental service companies.

SERVICE: Matlack carries 30-70% Sulfuric and other acids, corrosives, hazardous waste, petroleum products, and chlorine. Customers want the ultimate in protection for these tanks, to prevent unwanted corrosion, to ensure product (cargo) purity, and to extend the service life of the units.

HISTORY: Matlack has used a range of lining technologies such as rubber, fiberglass-reinforced products, Kynar®, Teflon®, and other various epoxy and phenolic epoxy coatings. Each lining system has presented different challenges and no single lining was versatile enough to cover a wide breadth of cargoes carried. Some of these linings have also been very expensive to install and maintain.

THE SOLUTION: Matlack now specifies the ChemLINE® tank lining to prevent unwanted corrosion to extend the service life of its tanks. ChemLINE® offers a superior solution at a competitive price and is versatile by being able to carry a large footprint of cargoes, including food-grade products.

“We know when ChemLINE® tanks are properly maintained, they outlast all other linings. Usually a flush wash or rinse is enough for a ChemLINE® cleaning.” - Matlack Leasing Director National Operations & Technical Services

A History of Performance

For more than a decade ChemLINE® coatings have withstood the tremendous stresses and extremes of chemical attack and abrasive wear. ChemLINE® has been proven worldwide under the most arduous operating conditions, from resisting the most aggressive chemicals to handling hot pipelines in sub-freezing temperatures, with a history of success. Based on this experience, the development of ChemLINE® 784 HS represents a quantum leap in chemical resistant polymer coatings.

ChemLINE® 784 HS Adds to Your Profits


ChemLINE® 784 HS Makes Application Easy

Save time and labor costs with ChemLINE®, which only requires a single coat application (12-14 wet mills/11-13 dry mills) with no solvent added.

Our coating process minimizes material waste, reduces disposal costs, and assures mixing accuracy through automation.
