Additin® RC 4211

Additin® RC 4211 is a barium-free corrosion inhibitor used in greases and metalworking fluids. It is compatible with metal substrates and provides corrosion inhibition, hydrophobic properties, low odor, non-staining characteristics, and thixotropic behavior. It is suitable for use in cutting oils, greases, metalworking fluids, and rust preventive oils.

Application Information
  • Rust preventatives, based on oils or solvents
  • Cutting oils
  • Greases
  • Additin® RC 4211 is a non-staining, low odor and Barium free anticorrosion additive giving excellent results on severe long term storage, in the salt spray cabinet and in Kesternich cabinet (alternating and constant climates).
  • Solvent based rust preventatives based on Additin® RC 4211 are forming homogenous and stable waxy protection layers; due to its very strong thixotropic properties the typical treat level of Additin® RC 4211 is much lower compared to other anti-corrosion additives. Mineral oil based rust preventatives based on Additin® RC 4211 are showing high stability protection layers and less draining-off on long term storage. Additin® RC 4211 is a soft waxy solid at ambient temperature. However it can be easily liquified if heated at 50°C . Due to its strong adsorption on metal surfaces and its hydrophobic character, Additin® RC 4211 can not be easily removed by mild alkaline washing (acc. to Volkswagen test VW 52.02). However, the cleaning operation can be done successfully with stronger waterbased cleaners or with cleaners based on hydrocarbons. Additin RC 4211 can also be
  • used as a corrosion inhibitor in lubricating greases.
  • At higher treatment level, Additin® RC 4211 gives nonnewtonian fluids and may have a significant variability in viscosity during storage. The viscosity can be influenced by shear strain.
  • Not suitable for circulating systems.

Solubility Data

Good solubility in mineral oils, synthetic base oils and white spirits. However, it is necessary to verify the solubility in the base oils used and the compatibility with other additives.
