Product Description
Pamolyn™ 347 fatty acid is a conjugated linoleic acid and oleic acid rich blend. The conjugated linoleic acid is produced synthetically by an Eastman process that isomerizes 9, 12-nonconjugated linoleic acid to the 9, 11- and 10, 12-conjugated forms, and controls the ratio of cis-trans to trans-trans isomers. Outstanding for low odor, pale color, and color stability, Pamolyn™ 347 fatty acid contains 38 to 44% conjugated diene fatty acids which makes it more reactive when compared with natural linoleic acids of similar linoleic content. Fast bodying of protective coating resins and excellent surface and through dry of their films are noted. Uses include production of epoxy resin esters; modifiers of styrenated and other alkyds; chemical intermediates for reactions involving conjugated unsaturation; and applications wherever dehydrated castor oil and/or fatty acids are used.

Do not store in carbon steel containers since fatty acids will react and discolor. Inside storage and "first in first out" inventory control is recommended. Storage at temperatures above 30°C should be avoided. Fatty acids are susceptible 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 product 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. Material will remain within product specification limits for a period of at least twelve months after shipment from Eastman''s production facilities, provided recommended storage conditions are observed. However, as neither the processing conditions for the product, nor the end use applications for which it is used can be anticipated and extreme conditions can affect the product quality, it is recommended 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.
