Eco-Rez™ 4237 C
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.

Alpha-Rez™ 3500 E
Alpha-Rez™ 3500 E is a low viscous, modified hydrocarbon resin that has high solubility and displays a good gel response to aluminum gelling agents. It also has a lower water pick-up and functions as a water balance regulator. The product has ideal pigment wetting properties causing inks to display a higher gloss. It is used in offset, grinding varnishes and letterpress applications.
Alpha-Rez™ 9250 E
Alpha-Rez™ 9250 E is a hybrid resin composed of visco-elastic hydrocarbons and hybrid resins that display a high viscosity and medium solubility. The product has good water balance, low misting and low tack properties. It can be used in offset inks using fast-running printing processes.
Burez® K79
Burez® K79 is a potassium soap of modified rosin with 80% solids, good stability and a low level of unsaponifiables. It is mainly used as an emulsifier for water-based adhesives.
Burez® NA18 502D
Burez® NA18 502D is a sodium soap of stabilized rosin with 18% solids, good stability and a low level of unsaponifiables. It is mainly used as an emulsifier in the emulsion polymerization system as well as in adhesives, particularly bottle labeling, in addition to uses in pigment resination.
