Product descriptions from the supplier
1.Raw materials
· Aluminum silver paste: Select floating, non-floating, electroplating imitation, fine silver, or flash silver types according to requirements.
· Resin: Solvent-based (such as acrylic, vinyl chloride-vinyl acetate, polyurethane); water-based (such as acrylic emulsion, polyurethane dispersion).
· Solvent/water: Solvent-based (alcohols, ethers, esters); water-based (deionized water).
· Additives: Dispersants, wetting agents, leveling agents, anti-settling agents, pH regulators, defoamers.
2. Formulation design
①. Determine the addition amount of aluminum silver paste:
o Pure silver ink: 6 - 10%
o Metallic flash ink: 5 - 13%
o Anti-corrosion/packaging ink: 10 - 30%
②. Selection of resin system:
o Give priority to resins with low acid value and low amine value to avoid reaction with the fatty acid on the aluminum surface.
③. Design of solvent/water system:
o Solvent-based: Compound alcohol, ether, and ester solvents, and control the volatilization gradient (fast-drying: slow-drying = 6:4).
o Water-based: Use deionized water as the main component, and add ethylene glycol monobutyl ether (≥70%) to adjust volatilization and wettability.
④. Addition of additives:
o Dispersant: Add 0.5 - 2% of the amount of aluminum silver paste (such as BYK - 190, TEGO Dispers 750W).
o Anti-settling agent: Fumed SiO₂, with an addition amount of 0.5 - 1%
o Water-based system: Adjust the pH to 8 - 9, and add a corrosion inhibitor to prevent hydrogen evolution.
