Sherwin-Williams has expanded its Macropoxy protective coating family with Macropoxy 80, designed for application over marginally prepared steel substrates and damp surfaces.

The high-build, HAPs-free epoxy fights corrosion from both immersion and atmospheric exposures and can be applied at temperatures as low as 0° F (-18° C), the manufacturer says. Macropoxy 80 is low VOC (<250 g/L) and is available in a semi-gloss finish in red oxide, grey or black.

Macropoxy 80 can be used in a variety of industrial applications.

A modified phenalkamine epoxy, Macropoxy 80 is recommended for use on water and wastewater tanks, structural steel, pipe, tanks and equipment in a variety of industrial applications. 

Surface Preparation

Because of its surface tolerance, Macropoxy 80 can be applied in adverse conditions, the manufacturer says. Steel substrates need only to be cleaned of loose paint or rust per SSPC SP2-3 Hand and Power Tool Cleaning before application.

The high-solids formulation (80%) reduces the chance of solvent entrapment, which can lead to premature coating failure, according to Sherwin-Williams.

The product is suitable for application in cold or dampness, said Narsi Bodapati, vice president of marketing for Sherwin-Williams Protective & Marine Coatings.

“Owners will appreciate the lower surface preparation costs involved,” Bodapati adds.
