Product name: XCR-322 High-Viscosity Resin
Gum Rosin Modified Octylphenol Resins.
Apparent: Light Amber Color, Brown Solid.
Viscosity: 11000--15000 mpa. s/250 (tested by pyramid viscosimeter) .
8000--10000 mpa. s/200 (samples: sesame oil=1:2 testing after dissolving within 2500) (tested by whirl-viscosimeter) .
Acid Value: <=25mg KOH/g
Softness Point: 160-1750
N-heptane Value: >=8ml/2g.250
Characteristics of Product:
Higher-configuration index, higher viscosity and elasticity. And so the dot is reappeared very well;the wetness of pigment is better and the printing inks made of these resins are transported very well during the process of printing. And so the density of transfer is much higher.
Good release of solvent and few residual solvent after printing can increase the velocity of inks curing and the drying of print matter.
The larger viscosity of dissolving and higher n-heptane value can make stability of finished inks for storing well and the value of viscosity is much lower, so the stability of print is much better.
Anti-emulsifying, very well balance between water and inks.
Improve the flying color of inks and then increase the adaptability of inks for high-speed print.
Use of Product:
The resins are suitable to manufacture high grade offset oil and improve the special characteristics of high grade gloss offset printing ink.
