Sherwin-Williams has added a new product to the Macropoxy family of high performance coatings. Macropoxy 80 is a high-build HAPs-free epoxy formulated for application over marginally prepared steel substrates and damp surfaces. The coating combats corrosion from both immersion and atmospheric exposures and can be applied at temperatures as low as zero degrees farenheit (minus 18 degrees centigrade).
A modified phenalkamine epoxy, Macropoxy 80 is recommended for use on water and wastewater tanks as well as structural steel, pipe, tanks and equipment in numerous industrial applications.
Because of its surface tolerance, Macropoxy 80 can be applied in adverse conditions, and steel substrates need only to be cleaned of loose paint or rust per SSPC SP2-3 Hand and Power Tool Cleaning before application. Its high solids formulation (80 percent) reduces the likelihood of the solvent entrapment that can lead to premature coating failure.
In addition to being HAPS-free, Macropoxy 80 is low-VOC (<250 g/L) and is available in a semi-gloss finish in red oxide, grey or black.
