Dymerex
Dymerex™ modified rosin is a pale, acidic, thermoplastic, high softening point resin. It is composed predominately of dimeric acids derived from rosin with lesser amounts of monomeric resin acids and neutral materials of rosin origin. Dymerex™ modified resin has high resistance to oxidation and does not crystallize from solutions or from solid compositions. It is compatible with many natural and synthetic film formers and rubbers. Being an acidic resin, it reacts readily with polyalcohols or hydrated lime to yield high melting derivatives.

Storage & Handling

Shelf Life
18 Months
Storage

 

Because of the extremely large surface area they present, flaked forms of resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or it could have an adverse effect on solubility in organic solvents. It is strongly recommended that strict control of inventory be observed at all times, taking care that the oldest materials is used first.

Dymerex™ Polymerized Rosin material will remain within product specification limit for a period of at least 18 months after shipment from Eastman's production facilities, provided storage conditions outlined in this data sheet are observed. However, as we can neither anticipate the conditions under which the resin is processed nor the end use applications for which it is used, we recommend that the material be tested upon receipt.
