Eco-Rez™ 4237 C is a rosin-modified resin that is formaldehyde and phenol-free, showing low or medium solubility together with a high viscosity in mineral distillates. Compared to other phenolic rosin resins, it gives better gel response, lower tack and a wider water window. Other advantages include good run resistance, low yellowing and odor and a high structure. Eco-Rez™ 4237 C is used in offset, web offset, heatset and coldset applications as well as in sheet-fed and gloss offsets and low odor inks. Lower color makes it ideal for use in overprint varnishes.
