For solvent-based and solvent-free systems,polysiloxanes,polyacrylates, and polyolefins are effective.

Pure polysiloxanes are also suitable but critical in terms of their compatibility, which can cause cratering.The best balcance between compatibility and incompatibility is achieved through organically-modified polysiloxanes.

Modification of the polysiloxane backbone with fluorine results in the socalled fluoro-silicones known for their very low surface tension and strong defoaming properties 

For waterborne systems,a wider range of chemical structures can be used due to the generally higher surface tension of these systems
