What challenges does ROC.3 address?
Combines rust and oil removal from steel surfaces to simplify pretreatment before zinc plating or on-site repair.

ROC.3 is a mildly acidic pretreatment formulation based on citric and phosphoric acids. It removes corrosion products and oils from steel and galvanized surfaces in a single operation without hydrochloric, sulfuric or nitric acid. Corrosion inhibitors delay re-rusting after treatment. Applications include pretreatment for zinc plating and surface preparation before maintenance coating of steel structures.
Combines degreasing and rust removal, reducing pretreatment stages for suitable steel and zinc-coated surfaces.
Formulated with citric and phosphoric acids rather than hydrochloric, sulfuric or nitric acid. It can be evaluated as an alternative pretreatment to conventional acid pickling before zinc plating.
Contains a corrosion inhibitor to delay rust recurrence after cleaning, allowing an interval before subsequent processing under the specified conditions.
The low-odor formulation reduces odor during pretreatment. Use workplace ventilation and personal protective equipment as specified in the SDS and operating instructions.
Product documentation includes the applicable Korean safety notification and test records.
No detection in 4 reported test items, including formaldehyde and benzene. The referenced Korean safety notification and assessment documents are available.
The referenced packaging passed the applicable child-resistant packaging assessment. Follow the product's storage and handling instructions.
A report covering 26 non-detected substance test items, including Pb, Cd, Hg and hexavalent chromium, is available. Refer to the report for its scope and test methods.
Based on the product catalog and available test reports. Refer to the original reports for methods and detailed conditions.
Larger Areas / Immersion and Application
The flowable liquid formulation is suitable for immersion treatment and large-area application.
Localized Areas / Brush Application
Brush application to vertical surfaces and localized repair areas uses the gel's retention properties to limit sagging and run-off.
Larger 5 kg and 20 kg packages are also available for on-site and industrial use.
Documented pretreatment applications include repairs to corroded bent sections on solar-support structures.
Removes rust and oil from corroded steel structures to prepare the surface for a compatible repair coating.
Can be evaluated as an alternative to hydrochloric- or sulfuric-acid pickling before zinc plating.
For rust removal from suitable tools, equipment and household items in accordance with product directions and safety precautions.
Rust removal and degreasing are followed by G·SAVE protective repair coating, integrating surface preparation and maintenance coating operations.
Review the intended use and application conditions before selecting a rust remover.
Combines rust and oil removal from steel surfaces to simplify pretreatment before zinc plating or on-site repair.
A mildly acidic product based on citric and phosphoric acids, without hydrochloric, sulfuric or nitric acid. Application conditions must be assessed for the substrate and contamination.
Consider the liquid for immersion or circulation cleaning, and the gel for vertical surfaces or localized areas where run-off should be limited.
