A customer inquired that during the production process of using colloidal palladium activators, the color of the activation solution will gradually become lighter, from brownish black to colorless, and the activation effect will significantly decrease. What is the reason for this?
Bigley Technology conducted an analysis based on on-site experience and the characteristics of the product colloidal palladium activator. As the colloidal palladium activator is a colloidal substance, metal palladium particles will not precipitate only in the colloid. The divalent tin ions in the activation solution surround the metal palladium particles, which can stabilize the solution.
When the colloidal palladium activation solution is kept in the air for a period of time, the activation effect will decrease, and the color of the activation solution will gradually become lighter. This is because the divalent tin ions in the activation solution are easily oxidized to form tetravalent tin ions, which cannot protect the metal palladium particles and make the palladium activation solution unstable, leading to a gradual decrease in the activation effect of the palladium activation solution.
Bigley reminds customers that although this colloidal palladium activator has good chemical stability, attention should still be paid to reducing the contact between palladium activation solution and air during the production process. After use, the lid should be immediately closed, which can effectively alleviate the oxidation of divalent tin to tetravalent tin and prolong the service life of palladium activation solution.
Therefore, in the production process of using colloidal palladium activators, we should pay attention to maintaining the palladium activation solution well, reducing contact with air, effectively extending the service life of the palladium activation solution, and saving production costs.
