Vanconol® MGR-82 Corrosion Inhibitor for Magnesium Alloys
Vanconol® MGR-82 Corrosion Inhibitor for Magnesium Alloys
Core Positioning
This document is designed for B2B decision-makers including R&D engineers, formulators, and procurement managers, providing comprehensive technical information on the Vanconol® MGR-82 corrosion inhibitor for magnesium alloys.
Product Overview
Vanconol® MGR-82 is a high-performance, chromium-free, water-based, low-VOC corrosion inhibitor specifically formulated for magnesium alloys. Utilizing an inorganic-organic hybrid formulation, it rapidly forms a dense protective film that effectively suppresses electrochemical corrosion of magnesium alloys in harsh environments such as humid conditions, salt spray, and acidic media. This significantly extends the service life of magnesium alloy components while reducing maintenance costs.

Key Advantages and Performance Characteristics
High corrosion inhibition efficiency: In a 3.5% saline solution test at 40°C, a 24-hour corrosion test on AZ31B substrate demonstrates a corrosion inhibition efficiency of up to 91%.
Broad pH adaptability: Maintains high adaptability across a wide pH range (e.g., 6.0-10.0).
Environmental compatibility and regulatory compliance: This product does not contain substances of very high concern (SVHC) as defined by EU REACH regulations, offering a more environmentally friendly and safer solution.
Primary Application Areas
This product can be widely applied in all fields requiring effective corrosion protection for magnesium alloys and multi-metal equipment:
Automotive Industry Applications: Suitable for corrosion inhibition during machining of magnesium alloy wheels, engine components, body structural parts, and other automotive workpieces.
3C Electronics Applications: Used as a corrosion inhibitor during cleaning and machining of magnesium alloy components in 3C electronics.
Aerospace Applications: Suitable for surface treatment of equipment components.
Other Applications: Suitable for surface protection of magnesium alloy materials in other applications with high environmental requirements.
Usage and Recommendations
Dosing Method: This product is water-soluble and can be added directly to the system or diluted and metered continuously and precisely via a dosing pump.
Recommended Dosage: The recommended addition level is 0.5-1% as supplied. The optimal dosage should be determined through dosage screening studies.
Compatibility: This product is compatible with most commonly used scale inhibitors, dispersants, and biocides/algicides for co-formulation. However, when formulating composite products, compatibility testing is recommended to ensure no precipitation occurs.
Packaging, Storage, and Safety
Packaging: Available in 25 kg and 200 kg plastic drums, or customized packaging upon request.
Storage: Store sealed in a cool, ventilated, and dry place, away from direct sunlight. This product is hygroscopic; reseal promptly after opening.
Shelf Life: 12 months.
Safety Information: Wear appropriate personal protective equipment (PPE) such as protective gloves and safety goggles during handling. If skin contact occurs, rinse thoroughly with soap and water. If eye contact occurs, flush immediately with plenty of water for at least 15 minutes and seek medical attention. Refer to the Safety Data Sheet (SDS) for detailed safety information.
