Peelable ink characteristics, uses and preparation

The peelable ink can cover up the printed and written characters and patterns effectively. After the ink is dried, the ink layer can be peeled off again to reproduce the original text and pattern. The original image and the text are still clearly reproduced. As always.

1. Features and uses

(1) The agent has strong hiding power, and it is impossible to see the covered text and pattern with the naked eye, that is, the confidentiality is strong.

(2) After the covering layer of this agent is removed, the original picture and the text are very clear. Will not affect the quality of the original image and text due to the cover layer.

(3) The cover layer is easy to peel off. Simply remove the corner of the cover layer and remove it completely.

This agent is mainly used for confidential documents, data, lotteries, etc. It is also used for games and entertainment.

2. Raw materials

(1) Ethylene-vinyl acetate copolymer see 16 (the main raw material of this agent. Use industrial products.) New type of writing cover liquid.

(2) Xylene "target = _blank> xylene see five (9) multi-functional paint remover "target = _blank> paint remover. This agent is used as a solvent. Use industrial products.

(3) Toluene VI (7) Nitrile rubber adhesive. This agent is used as a solvent. Use industrial products.

(4) titanium dioxide see a <11> powder eye shadow block. This agent is used as a filler. Rutile titanium dioxide is used.

(5) Antimony trioxide see seven (eight) epoxy resin anticorrosion coating. This agent is used as a colorant. Use industrial products.

(6) aluminum powder see seven (eight) epoxy resin anti-corrosion coating. This agent is used as filler and colorant. Use industrial products.

(7) Silicon dioxide see second (eight) remove tartar toothpaste. This agent is used as a filler. Colloidal silica is used.

4. Preparation and use methods

Formula one preparation. The ethylene-vinyl acetate copolymer (45%) was dissolved in xylene solvent, stirred and mixed and then added titanium dioxide powder, ferric oxide, aluminum powder and colloidal blue; silicon, grinding with a ball mill 8 lOh can be out material.

Formula two preparation. The ethylene-vinyl acetate copolymer (40%) was dissolved in a toluene solvent, mixed with titanium dioxide powder and aluminum powder after stirring, and ground with a ball mill for 8 to 20 hours.

In use, the agent is screen printed (or gravure printing) and the print is overlaid on the preprinted offset text. After the solvent is volatilized naturally, the coating is formed.
