Product Description
Pamolyn™ 240 fatty acid is a linoleic acid-rich blend derived wholly from a tall oil fatty acid source. It is a pale, oily liquid with low odor, and is highly resistant to discoloration on exposure to heat and light. Because of the near absence of saturated fatty acids, this product has an exceptionally low titer. Pamolyn™ 240 fatty acid contains a low percentage of unsaponifiables and resin acids. Pamolyn™ 240 fatty acid is designed especially for the protective coatings industry for production of pale, color retentive, fast drying alkyds and epoxy resin ester coatings. Other uses include applications that require both wetting and drying properties, such as printing ink vehicles and caulking and sealant compositions

Storage
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.
