Product Description

 
 

 

PU Environmentally-friendly Polyurethane Ester Compound Ink Series 

    PU series ink is an ester-soluble composite printing ink. It is applicable to most printing substrates and does not contain benzene, ketone solvents, conforming to the environmental protection requirements.  

 

Product Features: 
1.The product is applicable to the printing of films with corona sides such as OPP、PET and nylon, etc., with stable printing quality, smooth, delicate and natural patterns, and strong stereoscopic impression and beautiful colors. 
2.The solvent is released quickly, with fewer residues, free of printing smell. The butyl ester should not be used, which has residue, so it is recommended to use propylene glycol monomethyl ether acetate (PMA), with special moisturizing performance, applicable to the printing of food compound packages. 

 

Printing parameters: 
Ink printing viscosity depends on the specific circumstances. Low viscosity is recommended for high speed and high viscosity is recommended for low speed. 
1. The recommended viscosity for high speed printing: 
       White ink: 14-18S/3#  Zahn Cup 25 ℃
       Color ink: 16-20S/3 # Zahn Cup 25 ℃
2. The recommended viscosity for medium speed printing: 
       White ink: 16-20S/3 # Zahn Cup 25 ℃
       Color ink: 18-22S/3 # Zahn Cup 25 ℃
Customers can make adjustment depending on specific requirements. 
3 Diluents: ethyl ether EAC, n-propyl ester PAC, butyl ester NBAC or propylene glycol monomethyl ether acetate (PMA)  

 

Standard Color:  
With reference to Fu Li Cheng color atlas  

 

Matters needing attention:   
      It is recommended that the printing of ink should be dependent on the weather dryness and humidity. It should be adjusted and selected according to the type of printing equipment and the specific printing conditions; if more dry retarders are used, the solvent residue in the ink film will be increased.
