Rust removal with DEHSCOFIX® RR140

DEHSCOFIX® RR140 from Innospec is a clear choice for customers seeking an intelligent rust removal solution.

DEHSCOFIX® RR140 is an aqueous solution of (S,S) ethylenediamine-N,N'-disuccinic acid (EDDS). As a metal chelating agent, it has many useful properties, which lead many to prefer its use over other chelants such as EDTA:

• Extreme selectivity for transition metals, such as copper and iron
• Suitable for hard water conditions
• Effectivity at mild pH and low concentrations
• Avoids hydrogen embrittlement of the metal
• Readily biodegradable status
• Enables use in soil remediation

The absence of hazardous co-products and impurities associated with the production of EDTA provide further advantages for using DEHSCOFIX® RR140.
