Product Description
Staybelite™ ester 3-E ester of hydrogenated rosin is a pale, viscous, balsamic liquid with the resistance to oxidation and discoloration characteristic of the Staybelite series of resins. The tacky, highly adhesive resin can be readily emulsified, and serves as plasticizer for a wide range of film formers.

Staybelite ester 3-E is broadly compatible with many other components, and it has found wide acceptance in hot melt, pressure sensitive, and laminating adhesives. In general, it finds use where there is a need for a pale, non-oxidizing, color-stable, highly tacky liquid resin.

Compatibility and Solubility

Compatible at all ratios, or in limited but practically useful proportions, with resins, waxes, plasticizers, and film formers such as natural and synthetic rubbers, chlorinated rubber, nitrocellulose, and ethylcellulose.

Soluble in esters, ketones, higher alcohols, glycol ethers, aliphatic and aromatic hydrocarbons, and chlorinated solvents. Insoluble in ethanol and water.

Solubility Parameters, 50% resin concentration. 7,0-11,1 in Class I solvents - weakly hydrogen-bonded; 7,4-10,6 in Class II solvents - moderately hydrogen-bonded; 9,5-11,9 in Class III solvents - strongly hydrogen-bonded.

Staybelite™ ester 3-E ester of hydrogenated rosin is supplied in open-head steel drums with a net weight of 190 kg, on pallets containing 4 drums each, from Eastman production facilities in the Netherlands and from warehouses located in Europe.

Inside storage is recommended. Storage at temperatures above 30°C should be avoided.

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 the solubility of the resin in organic solvents or on its compatibility with polymers. Accordingly, it is recommended that strict control of inventory be observed at all times, taking care that the oldest material is used first.

Staybelite™ ester 3-E ester of hydrogenated rosin material will remain within product specification limits for a period of at least twelve months after shipment from Eastman production facilities in the Netherlands, 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.

Properties reported here are typical of average lots. Eastman makes no representation that the material in any particular shipment will conform exactly to the values given.
