C-21 Series Printing Ink
Carpoly C-21 series is high class semi matt printing ink specially designed to satisfy the demands of super high abrasion proof and scratch resistance of surface printing on plastic. It can be use for pad printing and screen printing. It is self-drying solvent printing ink; it brings excellent printing stability and excellent release of the solvent; and it is excellent in multilayer printing.
1. Application scope:Generally used on products like mobile phone covers, toys, keystrokes and mouse made from thermoplastic materials such as ABS, acrylic, PC, PS, hard and soft PVC materials.
2. Performance characteristics:C-21 ink series is subtly made from special materials, thus gives excellent abrasion proof and scratch resistance, meanwhile, it is as excellent as in sweat stains resistance and gasoline resistance.

c. Please choose one of the thinner ranged in fast, middle and low drying speed according to the actual working environment.
d. Please choose the prompt printing film stencil (77lines-150lines/cm) according to the expected print results.
e. In order to reach the excellent print results of tiny lines, patterns and characters, you can add some J-21-100 easy-congeal ointment, thus to avoid diffusion, burrs, and blurring of the print layers.
5.Notes:
a. Please conduct a trial before printing to avoid quality failure causing from materials differences.
b. If the adherence is bad after the printing, or if the printing process is bad, it may highly be caused by the floating parts of the added plastic agent or other addictive on the surface of the plastic, or might be reason of static electricity.
