Mineral Oil Defoamer
CAS Number: 8012-95-1
Mineral-oil-based defoamer compounded with hydrophobic silica and emulsifiers for effective foam control in waterborne paint manufacturing, paper coatings, and construction chemicals. It offers excellent compatibility with waterborne coating systems without the crater-formation risk associated with silicone-based defoamers. Suitable for both in-can and in-process foam control.
