Product Overview
Exotop® NFWA Exothermic Topping Compound
Exotop® NFWA is a premium exothermic topping compound engineered specifically for non-ferrous foundry applications. Designed to ignite rapidly upon contact with molten metal, it generates additional heat within the riser while forming a durable hard crust that helps minimize heat loss during solidification.
By maintaining hotter risers for longer periods, Exotop NFWA helps foundries improve feeding efficiency, reduce shrinkage-related defects, and optimize casting yields. Its low-smoke, low-odor formulation also supports a cleaner working environment without compromising thermal performance.
Whether you're producing aluminum, bronze, brass, or other non-ferrous castings, Exotop NFWA provides consistent, dependable performance that helps improve casting quality while simplifying the pouring process.
Exotop® NFWA
Casting Defects Cost Time and Money
Maintaining proper riser performance during solidification is critical to producing quality castings. Premature heat loss can lead to inadequate feeding, shrinkage defects, lower yields, and increased rework.
Exotop NFWA helps maintain riser temperatures by generating exothermic heat immediately after application, extending feeding performance during solidification.
