Defoamer
CAS Number: 8050-81-5
Versatile mineral-oil-based defoamer formulated for use in waterborne coatings, adhesives, and construction materials to rapidly destroy foam and prevent its reformation. It migrates quickly to the air-liquid interface to destabilize foam bubbles, ensuring smooth application and defect-free film formation. Compatible with most waterborne binder systems.
