Darkening of the paint, reduced hiding power, and rough film:

Cause: Excessively high acid value, prolonged processing, or high-speed stirring can damage the integrity of the surface coating and the silver paste itself.
Solution: Optimize the process flow, control processing time, and adjust the stirring speed appropriately.
Silver paste is difficult to disperse:

Cause: Improper solvent or resin selection.
Solution: Adjust the resin-to-solvent ratio. If the product is too fine and difficult to disperse, increase the soaking time and ensure uniform stirring.
Silver paste is black or yellowing:

Cause: Poor sealing or excessively high baking temperature.
Solution: Ensure a good seal and bake at an appropriate temperature.
Poor leveling in building materials applications:

Cause: Improper solvent or resin used.
Solution: Re-adjust the solvent and adjust according to the resin properties.
Particles on the sprayed surface:

Cause: Possible oxidation, poor dispersion, or impurities in the product. Solution: If the problem is oxidation, retest the sample. If impurities are present, filter through a 325-mesh filter cloth before mixing.

Ink Dosage:

Dosage: The typical dosage of silver paste in ink is 6%-10%, though the specific ratio can be adjusted based on customer needs.

Note: To improve the dispersion and polishability of the aluminum-silver paste, dispersants or other related additives may be added in appropriate amounts, but the selection should be based on specific needs.
