Vanconol® MGR-810 Magnesium Alloy Corrosion Inhibitor

Product Overview

Vanconol® MGR-810 is a high-performance, chromium-free, waterborne, low-VOC corrosion inhibitor developed for magnesium alloys. Based on an organic composite formulation, it has been validated in simulated coolant systems: it rapidly forms a dense protective film on magnesium alloy surfaces, effectively inhibits electrochemical corrosion of magnesium alloys in coolant systems, significantly extends the service life of magnesium alloy components, and reduces maintenance costs.

Key Advantages and Performance Features

  • High corrosion inhibition performance: in a 50% ethylene glycol aqueous solution at a constant 88 °C with 2% corrosion inhibitor dosage, AZ91D magnesium alloy corrosion testing showed that the substrate surface remained bright and unchanged after 7 days; after 10 days, the corrosion mass loss of the substrate was only 30 mg.
  • Environmental compatibility and regulatory compliance: contains no substances of very high concern under EU REACH or similar regulations, making it more environmentally sound and safer to use.

Main Applications

  • Automotive industry: corrosion inhibition during processing of magnesium alloy wheels, engine blocks, cooling system lines, radiator magnesium alloy components, body structural parts, and similar parts.
  • 3C electronics: corrosion inhibition during cleaning and processing of magnesium alloy components for 3C electronics.
  • Aerospace: surface treatment of equipment components.
  • Others: surface protection of magnesium alloy materials with demanding environmental requirements.

Recommended Usage

  • Dosing method: water-soluble liquid; it can be poured directly into the system or, after dilution, metered continuously and precisely via a metering pump.
  • Recommended dosage: 0.5-1% as supplied; the specific dosage should be determined through dosage screening evaluation.
  • Compatibility: compatible and formulable with most common scale inhibitors, dispersants, and biocides/algaecides; compatibility testing is recommended before preparing compounded formulations.

Packaging, Storage and Safety

  • Packaging: 25 kg and 200 kg plastic drums, or customized to customer requirements.
  • Storage: keep sealed in a cool, ventilated and dry place, away from direct sunlight; this product is hygroscopic, so reseal promptly after opening.
  • Shelf life: 12 months.
  • Safety: wear protective gloves and goggles during handling; rinse skin contact with soap and water; in case of eye contact, flush with water for at least 15 minutes and seek medical attention.
