ADDITIN® RC 4955

ADDITIN® RC 4955 is a high-performance corrosion inhibitor package designed for the formulation of water-based rust preventives. Based on calcium sulfonate technology and emulsifier components, it enables the preparation of highly stable oil-in-water emulsions that provide reliable corrosion protection for metal surfaces.

The additive package helps formulators achieve excellent performance in corrosion testing while forming an oily protective film with outstanding edge coverage. Its balanced formulation supports both emulsion stability and long-lasting protection in demanding industrial environments.

• Effective corrosion protection for ferrous metals

• Excellent performance in salt spray and humidity testing

• Outstanding emulsion stability

• Forms a durable oily protective film

• Excellent edge protection

• Suitable for water-based rust preventive systems

• Compatible with a variety of mineral and synthetic base oils

• Water-based rust preventives

• Temporary corrosion protection fluids

• Metal preservation and storage fluids

• Industrial protective coatings and treatments

• Corrosion protection for manufactured and machined parts

ADDITIN® RC 4955 is designed for use in oil-based concentrates that are subsequently emulsified with water. Its technology supports the formation of stable emulsions and robust protective films, helping formulators develop corrosion protection systems that combine easy application with reliable performance. The resulting emulsions provide effective protection against humidity and salt-induced corrosion while maintaining excellent film coverage on complex part geometries.
