Rosin modified phenolic resin series
This series of resins is modified by phenol and aldehyde based on the superior quality pinus rosin, which partial of them are as a vehicle of liquid ink resins. It has performances of high softening point, high molecular weight, high solubility, high ;viscoelasticity and excellent pigment wetting. The ink made from this series of resins has the characteristics of fast drying speed, high gloss and good abrasion resistance. It can be widely used in different grades of offset bright ink, offset rotary ink and thermosetting rotary ink.
