NOTAR Ag-1080

FEATURES

• Suitable for jewelry, silverware, and many industrial processes.
• Forms a tenacious transparent film on top of the clean silver surface without affecting the silver luster.
• Does not affect the electro-characteristics.
• Effectively prevent silver from tarnishing, can pass most sulfide corrosion test.
• Easy to apply, safe and environmental friendly.
• Highly soluble in water.
• Highly compatible with printing ink in later process
• Halogen free and compliant with RoHS restrictions

RECOMMENDED USES

• Preparation of aqueous solution
  1. Heat up NOTAR Ag-1080 to 40°C (recommended in water bath), and keep stirring until it becomes uniform liquid.
  2. Draw required amount of NOTAR Ag-1080 and dilute it in water that has been preheated to 55~60°C to make up 5% aqueous solution.
• Anti-tarnishing process
  1. Thoroughly clean up the surface of the silver work piece. Make sure it is free of grease and oxidation layer. Tacklean Ag-108GC from PhilChem Ltd. is recommended as silver cleaner.
  2. Rinse the work piece with water.
  3. Blow it dry with cool air.
  4. While keeping the readily prepared 5% aqueous solution of NOTAR Ag-1080 around 55~60°C, dip the work piece in the solution for 5 minutes.
  5. Bring up the work piece and rinse it thoroughly with warm water (40~60°C).
  6. Blow it dry.
• Remarks
  • The dilution rate of the aqueous solution of NOTAR Ag-1080 can be adjusted by the customer; usually the lower the dilution rate, the better the protection.
  • The dipping time can also be adjusted; the longer the dipping time, the better the protection.

STORAGE

• Should be sealed and stored in a cool dry place away from direct sunlight
