1. Rust preventatives for temporary rust protection and longterm rust

protection

2. Corrosion inhibitors for water soluble fluids (Emulsion) / oil based fluids /

synthetic fluids / cleaners

Agenda


What are the requirements?

• Indoor or outdoor protection?

• Time of protection

• Easy to remove

• Film thickness

• No Labelling

• Barium free

• Light colour

• Dewatering effect

• Handling at room temperature

• Oil or water soluble

Rust protection is challenging

Applications for rust preventatives

• protection against corrosion to metal parts after machining or forming

• Metal protection during storage (outside and inside storage)

• Oversea shipments (shipment of engine blocks)

• Longterm protection, e.g. Harbour bridge in Sydney, underbody protection (cars)

• World Corrosion Organization: 3% of the BIP of industrialized countries are being

destroyed by rust


Examples for rust


Test methods for rust preventatives

Salt Spray Test

DIN EN ISO 9227 (NSF)

Humidity Test

DIN 50017 (KTW method)

• Metal sheets are dipped into the rust

preventative (16h for solvent based fluids / 2h

for oil based fluids)

• Metal sheets are placed into the salt spray

chamber

• Regular control for rust points

• Metal sheets are dipped into the rust

preventative (16h for solvent based fluids/ 2h

for oil based fluids)

• Metal sheets are placed into the salt spray

chamber for 16h

• Sheets will be kept in the chamber for 8h

(Chamber is turned off during that time). 1

cycle is finished. Repeat the cycles until rust

points can be seen


ACL has developed a range of rust preventatives

Packages can be adjusted individually

• Each package can be adjusted blended with Oil or solvent. Normal

treat rate of the package is 5-20%.

• DW 553 (single dewatering additive) can be added to improve the

dewatering effect

• High molecular sulfonates can be added to improve the corrosion

protection properties (example CX 914 B)
