The principle of automatic decoloring pen reveals the automatic dissipation of ink colorant materials when air, high temperature and water are unstable at 100 degrees.
Pens leave marks on white paper because ink contains colorants. The secret of the rubber pen lies in this coloring substance.
Generally speaking, the stronger the color substance, the more stable the chemical properties and the clearer the handwriting. This pen has the opposite effect. It uses an unstable chemical as a pigment.
Unstable chemicals in brushes are afraid of air, high temperature and water. When encountering these things, this unstable chemical will slowly decompose and dissipate in the air, which is irreversible.

Precautions:
1. Because the chemical composition and physical properties of different materials are different, please do a small test before putting into production. Excessive formaldehyde content on some fabrics will destroy microcapsules in ink. If it is put into production without testing, the company will not bear any responsibility.
2. Please cover the pen cap in time after use and store it in a cool place to avoid direct sunlight, so that the effect will be smoother next time.
3. This product is only used for the identification of industrial production. Please don't use it to fill in important documents such as contracts and signatures.
4, pay special attention to the composition of wool, please do not use high-temperature ink, it is best to use an automatic fading pen. Special fabrics such as: sheep scar skin; Mirror leather; When you brush burnt leather with hot ink, you will leave deep scratches. (Note: Try to use all-white fabrics, such as ramie cotton and other dark fabrics. )
