Recent advances in diester coalescing solvents

We have also prepared the di-isopropyl esters of the higher adipic content stream. This has a vapor pressme similar to that of Coasol, but is slightly more water soluble. Finally, we have manufactured di-isopropyl adipate, which has the highest boiling point, the lowest vapor pressure and the lowest water solubility of all of this range of products. These preparations were undertaken to add to repertoire of products to suit the diverse requirements of the for-mulators of aqueous based systems. 

In virtually all cases, the dibasic esters gave a significant improvement in efficiency in reducing the MFFT for a given quantity of additive. The attempts are made to offer a tailor made solution to each individual polymer system employed in the development of aqueous based systems. The dibasic esters of the AGS acids group offer the opportunity for fine tuning, with the added advantage of low odor, low toxicity and excellent VOC status.
