Staybelite® Ester 10-A

Staybelite® Ester 10-A rosin is the glycerol ester of partially hydrogenated rosin. It is a pale, thermoplastic resin with excellent resistance to oxidation and discoloration. It is indicated for use as a tackifying resin for many adhesive applications, particularly pressure sensitive and emulsion types. In general, it is useful where there is need for pale, non-oxidizing, and color stable resin.

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.
