Technical Details & Test Data
Compatible with ethylcellulose, natural rubber, SBR (styrene-butadiene), polychloroprene, drying oils, alkyd resins, shellac, low molecular weight polyethylene, paraffin and microcrystalline waxes.
Soluble in aromatic, aliphatic and chlorinated hydrocarbons, esters, ketones, and higher molecular weight alcohols. Insoluble in methanol, ethanol, isopropanol and water.
Packaging & Availability
Dymerex™ Polymerized Rosin is packed in aluminum-kraft-bags of 25 kg net, and supplied on shrink-wrapped pallets of 28 bags each.
Storage & Handling
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.
