Product Description
Pamolyn™ 327B fatty acid is designed to be a direct replacement for G-H viscosity dehydrated castor oil in short to medium oil alkyds and copolymer alkyd resins. Alkyd resin vehicles based on Pamolyn™ 327B fatty acid retain the pale initial color of the fatty acid, and enamels made from them exhibit excellent color retention on baking and overbaking.

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.
