Corrosion Protection for Aqueous Parts Washing

Parts cleaned in aqueous systems can be left vulnerable to flash rust once oils and protective residues are removed. RPA-445 is an amine-based rust inhibitor added directly to wash solution to provide a protective barrier against corrosion, helping protect both the parts being cleaned and washer equipment constructed of mild steel.

Multi-Metal Safe Chemistry

RPA-445 is compatible with aluminum, brass, bronze, copper, iron, steel, and composites, as well as most precious metals, plastics, and rubbers.

Best Fit Applications

Application	Why It Fits
Mild steel parts	Helps prevent flash rust after cleaning
Mild steel washer equipment	Helps protect machine components from corrosion
Amine-compatible detergent systems	Designed for use with amine-based detergent chemistry, confirm compatibility before use
Multi-metal loads	Compatible with a wide range of metals and other materials

Additional information

Primary Applications	Corrosion protection on mild steel parts Washer equipment protection Extended rust protection after aqueous cleaning Multi-metal production environments
Features & Benefits	Powerful amine-based rust protection Multi-metal safe Biodegradable Safer for employees and the environment Non-flammable Non-corrosive No VOC or HAP
Important Compatibility Note	RPA-445 is amine-based and should never be mixed with nitrite-containing solutions. Confirm detergent chemistry compatibility with Better Engineering before adding RPA-445 to any wash system.
