Indelible ink, also known as silver nitrate ink, is primarily used for voting and elections due to its water-resistant properties. The silver nitrate content can be customized according to requirements (5%, 10%, 15%, 25%, etc.), with higher concentrations providing better marking effectiveness.
The photos below demonstrate the ink's durability, showing the color remains visible on fingers after 3 days and even after 14 days.
Application
Electoral stain serves as an effective security feature to prevent double voting in elections. The ink is typically applied to the left hand index finger, particularly to the cuticle area where removal is extremely difficult. Application methods vary based on circumstances and preferences, including dipping bottles with sponge inserts, bottles with brush applicators, spray bottles, and marker pens. For optimal results, allow the finger to dry for 15-30 seconds and expose to light before cleaning to ensure the mark remains visible for the desired duration.
