Cross-linking Trimer Acid produces toughness in polymers Emsorb® Esters offer superior color and color stability

T h e functionality of three carboxyl groups in Empol® 1043 Trimer Acid gives a cross-linking action which produces a toughness t h a t ' s highly desirable in specialty resin systems.

T h e superior color and color stability of E m s o r b Sorbitan and Ethoxylated Sorbitan Esters is demonstrated by t h e d a t a shown below. E m s o r b Esters are derived from t h e finest quality E m e r y fatty acids, and manufactured to exacting s t a n d a r d s , t h u s assuring t h e batch-to-batch purity and uniformity essential for consistency and perfection in finished products. Explore E m s o r b Esters for use in your products. W r i t e now for folder containing specifications and typical properties.

Other characteristics of this unique liquid tribasic acid are: light color (9 Gardner), a high trimer acid content (70% ), good compatibility with epoxy resins, and the increased flexibility it imparts to cured epoxy systems, with t h e retention of excellent tensile strength. A second E m e r y trimer acid, Empol 1040, with a higher trimer acid content of 9 1 % , has found principal application as a flexibilizer for epoxy resins. W h y not investigate these unusual tribasic acids to see w h a t t h e y can contribute to the success of your products. Use coupon to request d a t a sheets and evaluation samples.
