Mascoat® 250P
- Chemical Family
- Epoxy & Epoxy Derivatives
Mascoat® 250P is a high solids aluminum epoxy mastic primer that provides excellent corrosion protection over marginally clean substrates up to 250°F. It is intended for use under Mascoat’s insulating coatings, but can also be top-coated with epoxies and/ or polyurethanes. It is predominantly used on structural steel, steel tanks, barges, refineries, petrochem plants, power plants, railcars, pulp & paper mills, and other facilities as recommended.
