Mineral Oil Defoamer for Adhesives and Sealants

CAS Number: 8042-47-5

Mineral oil-based defoamer is a cost-effective antifoam agent used to suppress foam formation and eliminate air entrapment in waterborne and reactive adhesive and sealant manufacturing processes. It is particularly effective in high-shear mixing, dispensing, and application operations where air incorporation can lead to voids, surface defects, and reduced bond strength. The formulation combines hydrophobic mineral oil with hydrophobic silica particles for synergistic foam knockdown and persistent antifoam performance.
