Pentalyn® FC

Pentalyn® FC resin is the pentaerythritol ester of maleic-modified wood rosin. It is a pale, high softening point, high acid number, thermoplastic resin. It is highly soluble in typical organic solvents as well as in dilute aqueous solutions of alkalies, including ammonia. It is particularly suitable for modifying compositions based on alcohol-soluble and water-soluble film formers, to which it contributes high gloss, block resistance, fast solvent release, and good adhesion. Pentalyn FC modified rosin ester, an improved solubility version of Pentalyn 856 resin, meets the US FDA regulation for coatings on fresh citrus fruit.

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.
