Clariant has been developing readily biodegradable ingredients for the emulsion polymer industry for more than 14 years, and is today supporting the market with ingredients that, in addition to aiding APEO-free and low VOC formulations, are FDA approved and offer performance and productivity-boosting advantages.
The company was one of the first to launch a 100% APEO-free alternative to replace AP derivatives for the manufacture of binder emulsion polymers. In addition to its low VOC levels, Emulsogen EPA 073 is now one of few anionic emulsifiers with FDA approval.
Productivity is increased through control of low grit levels during the polymerisation process and the achievement of small and narrow particle size distribution.
The reduced grit/coagulum levels allow higher conversion rates of monomers during polymerisation and also cut-down on cleaning time due to longer intervals between cleaning cycles. Emulsogen EPA 073 is also easy to handle, having a crystallisation point below 5°C.
When combined with nonionic emulsifiers like Emulsogen LCN 287 or Emulsogen LCN 407, these APEO-free emulsifiers offer increased latex stability, better shelf life and improved stabilising against shear forces and electrolytes that can impact negatively on emulsion performance.
