Is the antifoam/defoamer compatible with the process?

Antifoams and defoamers are generally inert chemicals consisting of a liquid (e.g., silicone, mineral oils, or hydrophobic surfactants) and a hydrophobic solid (e.g., fatty acids, fatty alcohols, silica, or wax). Ultimately, the antifoam/defoamer you select should have a balance of compatibility and incompatibility. It should be compatible enough that it effectively disperses in the foaming medium.

Will the antifoam/defoamer cause deposit issues?

The antifoam/defoamer should be sufficiently compatible within the solution so as to not create deposits.

Will the antifoam/defoamer negatively affect the catalyst I am using?

The antifoam/defoamer should not negatively impact any catalysts used in the process.

Key Considerations for Selecting an Antifoam/Defoamer

Click to Expand Foam is created when gas is introduced and trapped within a solution that contains surfactants. It can consist of large bubbles at the surface of the solution […]
