Description
Fast-cure high-build epoxy for marine maintenance — rapid return to service
Did you know
- The Sherwin-Williams Macropoxy 646 is a high-solids, fast-drying polyamide epoxy mastic. It builds on existing Macropoxy technology, with a mildew-resistant version, Macropoxy 646MR, launched in 2019.
- Within the Sherwin-Williams Macropoxy family, the Macropoxy 646 is a versatile, general-purpose epoxy mastic. The Macropoxy 646-100 is a low VOC version, while Macropoxy 646 FF is a flake-filled variant offering enhanced edge protection, and Macropoxy 646 N is specifically designed for nuclear power plant applications.
- This model is chosen for its versatility, fast-drying properties, and surface tolerance, allowing application to marginally prepared steel surfaces. It offers a 1:1 mix ratio, making it user-friendly for both new construction and maintenance projects.
