Defoamer, Solvent-borne, Speciality Additive

VP 5088 Silicone defoamer

5088 Silicone Defoamer is a high-performance, non-ionic emulsion engineered specifically for demanding industrial environments where foam control is critical for operational efficiency. Composed primarily of organopolysiloxanes and synergistically blended polyether components, this specialized formulation excels in both rapid knockdown (defoaming) and long-term suppression (antifoaming) across a broad spectrum of pH values and temperature ranges. Its molecular architecture allows for excellent dispersion in aqueous systems without causing surface defects like “fish-eyes” or cratering in sensitive coating applications. In modern manufacturing, foam can significantly impede heat transfer, reduce vessel capacity, and cause mechanical damage to pumps; 5088 effectively addresses these challenges by destabilizing the lamellar structure of micro and macro-bubbles. Furthermore, its chemical stability ensures that it remains active even under high-shear conditions or during prolonged storage. As a versatile chemical additive, 5088 Silicone Defoamer represents a robust, specialized solution for maintaining process integrity, enhancing product quality, and reducing overall chemical consumption in diverse industrial sectors globally.
