Detailed Introduction:

The rosin modified phenolic resin with high molecular weight and low acid value is prepared by the reaction of p-teroctylphenol with rosin, polyol and formaldehyde. Because of its unique honeycomb structure, it can be well wetted with pigments, and can be properly reacted with gel agent to obtain a certain viscoelastic binder, so it is widely used in lithographic offset printing ink.
P-tert butylphenol can also be used in printing inks, such as rosin modification, offset printing, and advanced gravure printing.
