Foral® AX

Foral® AX rosin is a thermoplastic, acidic resin produced by hydrogenating wood rosin to an exceptionally high degree. It is the palest, most highly stabilized rosin commercially available. Compared with Staybelite® resin, a hydrogenated rosin long established and widely used for its pale color and high oxidation stability, Foral AX resin has better initial color and color retention, and even greater resistance to oxidation. It is especially indicated as the tackifier and resin modifier in solvent adhesives and hot melt applied coatings and adhesives that must excel in these properties. Foral AX resin is particularly suited to food contact applications.

Storage and Inventory Control

Pastillated or flaked resins may fuse, block, or lump during hot weather months, if stored near sources of heat, if double or triple stacked, or if stored for prolonged periods of time. These forms of resin are prone to gradual oxidation, some more so than others. This could result in darkening and/or could have an adverse effect on solubility in organic solvents. Care should be given to minimize opportunities for product oxidation throughout processing. Accordingly, it is strongly recommended that proper storage conditions and strict control of inventory be observed at all times, taking care that the oldest material is used first.
