Serfunsa offers a wide range of refractory coatings formulated to improve surface finish, reduce metal penetration, and minimize common casting defects.
Formulations are based on silica, zircon, graphite, alumina, mica, and other refractory materials, allowing us to adapt each product to specific alloys, sand systems, and production conditions.
Our adhesive products are designed for core and mold assembly in both production and jobbing foundries. Serfunsa adhesives provide: Fast initial tack Strong bonding Compatibility with all major binder systems Stability during oven curing and post-curing These products are engineered to maintain strength and reliability throughout the casting process.
Serfunsa manufactures release agents for wood, metal, and permanent molds. These products ensure clean release while preventing contamination of sand or binder systems. Our release agents are designed to: Improve mold life Reduce sticking and buildup Support consistent casting quality
These products are formulated to ensure smooth, uniform application and to maintain dimensional stability throughout the casting process. Our mudding and sealing compounds are engineered to resist cracking, shrinking, rolling, or peeling during drying, handling, and use. Once applied, they provide effective surface sealing and repair, helping to maintain mold and core integrity and supporting consistent coating performance.
Serfunsa develops and supplies foundry additives designed to improve process stability, enhance sand performance, and reduce common casting defects. Our additives are formulated to work effectively within a wide range of sand systems, alloys, and molding processes. By carefully controlling composition and application parameters, Serfunsa additives help foundries improve consistency, reduce variability, and achieve more reliable casting results under real production conditions.
In addition to standard additives, Serfunsa designs specialty products tailored to specific foundry challenges. These solutions are developed in close collaboration with customers, taking into account unique process requirements, production constraints, and quality objectives. Through custom formulation and technical support, Serfunsa specialty products provide targeted solutions where conventional products are not sufficient, supporting improved casting quality and operational efficiency.
