Novel defoamers for architectural systems - how to optimize structures for an ideal efficiency / compatibility profile

 
Formation of foam - during the production process as well as during the application step - can be a real troublemaker in coatings so there is a desire for constant progress in development of air management additives. On the one hand, this involves the optimization of chemical compositions of defoamers. For polyether siloxane based defoamers, this typically includes the variation of siloxane backbones as well as polyether group modification. Finetuning of microstructures for hydrophilic & hydrophobic building blocks helps to ensure needed levels of compatibility. On the other hand, a smart setup in testing can significantly support new developments. For Architectural formulations, this includes dynamic foam behavior assessment e.g. via videos as well as automated testing setups & automated defect detection.
