Chemical Resistant Coatings

Unsurpassed concrete protection and chemical containment in the electronics, chemical processing, waste treatment and related industries.


NovoRez® coatings uniquely combine epoxy Novolac and polysulfide technology. This results in high acid, caustic and solvent resistance along with elastomeric qualities for steel and concrete substrates. Typical applications include oil field tank linings, secondary containment, chemical process floor areas and hazardous waste facility flooring.

NovoRez® Case Story

NovoRez® Acid Resistant coating used for secondary containment of up to 98% sulfuric acid.

Sloss Industries Corporation is one of the nation’s leading manufacturers of coke for iron and steel production. The growth of the steel industry and rise in production created a need for additional storage of sulfuric acid at the Birmingham Plant. When choosing a contractor, Sloss Industries chose G & S, LLC because of their experience and ability to meet the plant’s high safety and Insurance requirements. In addition, PolySpec® was chosen to provide the material because of our long history of success in the chemical industry, breadth of chemical coatings and linings product line, and local technical representation.


PermaRez® reinforced composite lining systems are intended for the severest immersion conditions. They offer the advantages of outstanding chemical resistance, low coefficient of expansion and high tensile strength. This seamless lining system provides a surface that is impermeable to chemicals yet weighs and costs significantly less than acid-proof brick construction. This makes the system ideal for truck unloading areas, process floors, trenches and tanks.

PermaRez® Case Story

PermaRez Lining System reinforces weakened substrate lengthening the life of vital secondary containment.

Delavan Spray Technologies has been one of the world’s largest manufactures of spray nozzles for combustion in both domestic and commercial applications for over 60 years.
The secondary containment area for the nozzle dipping machine became severely eroded after years of constant chemical exposure.
The PermaRez® Reinforced Lining exceeded the chemical resistance requirement, and also strengthened the weakened substrate lengthening the life of the area.


PolySpec/Thiokol continues to improve the THIOKOL® product line to include coatings that are resistant to even more aggressive chemicals. These chemical resistant coatings offer long-term protection from intermittent and continuous exposures to acids, caustics, solvents and fuels.
