JY-277B Rust Preventive Coating for Silver and Copper

Excellent Rust Protection: JY-277B protects a wide range of non-ferrous metals and their coatings with good corrosion and salt spray resistance.

Safe Halogenated Hydrocarbon Solution: JY-277B is non-flammable and safe to use.

EASY TO USE: Simply apply JY-277B evenly to the appropriate workpiece to provide effective protection.

No Damage to the Workpiece: JY-277B will not corrode the workpiece and will maintain the original appearance of the workpiece.

High Efficiency: JY-277B works faster than similar products.

Precious Metal Adornments and Their Coatings: In the jewelry and luxury goods industries, JY-277B is a go-to for safeguarding gold and silver items and their plated surfaces. It ensures that these precious pieces retain their luster and integrity over time, even in less-than-ideal storage or display conditions.

Electronics and Electrical Components: Copper is widely used in electronics due to its conductivity. JY-277B is essential for protecting copper components and their silver or copper plating in circuit boards, connectors, and other electrical parts. This protection is crucial for maintaining the reliability and longevity of electronic devices, preventing corrosion-induced failures.

Antique and Decorative Metalware: For antique copper artifacts or decorative metal pieces, JY-277B provides a protective layer that preserves their historical and aesthetic value. It shields them from environmental factors that could cause deterioration, allowing them to be enjoyed for generations to come.

Marine and Coastal Applications: In marine environments where saltwater and humidity are prevalent, JY-277B offers long-term protection for metal fittings, fixtures, and equipment on boats, docks, and seaside structures. It helps prevent corrosion caused by the harsh coastal conditions, reducing maintenance costs and extending the lifespan of these assets.
