Sherwin-Williams Beats the Cold and Damp with Macropoxy 80; HAPs-free epoxy coating resists corrosion in marine and offshore applications.


Sherwin-Williams has launched Macropoxy 80, a high-build HAPs-free epoxy coating formulated for application to marginally prepared and damp surfaces in marine and offshore applications. The coating combats steel corrosion caused by immersion in salt and fresh water as well as from atmospheric exposures and can be applied at temperatures as low as 0o F (-18o C). A modified phenalkamine epoxy, Macropoxy 80 is recommended for use in coastal areas, salt and fresh water immersion, bilges and wet void areas, water and wastewater tanks, underwater hulls, and decks and superstructures. It can also be used as an anti-corrosive primer in an underwater hull system with anti-fouling coatings. 


Because of its surface tolerance, Macropoxy 80 can be applied in the dampest 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%) reduces the likelihood of the solvent entrapment that can lead to premature coating failure. “When applying coatings in dampness or cold are factors in your project, Macropoxy 80 is the product for you,” said Narsi Bodapati, Vice President of Marketing for Sherwin-Williams Protective & Marine Coatings. “Owners will appreciate the lower surface preparation costs involved while still getting the performance they require. And like our other proven products in the 20-year-old Macropoxy line, this coating is high performance and versatile.”


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. You can choose between a standard hardener for applications between 40°F (4°C) and 120°F (49°C) or a low-temperature hardener for applications between 0°F (-18°C) and 77°F (25°C).
