VP 5055 Silicone-free defoamer

Name: VP 5055 Silicone-free defoamer - Vortex
SKU: 5055

The 5055 Silicone-free defoamer is a high-performance, polymer-based antifoaming agent specifically engineered for industrial systems where silicone contamination must be strictly avoided. Composed primarily of specially modified hydrocarbons and fatty acid derivatives, this defoamer effectively destabilizes foam by reducing surface tension at the gas-liquid interface without the adverse effects of cratering or orange-peel defects often associated with silicone oils. Its unique chemical architecture allows for rapid bubble rupture and long-lasting foam suppression in complex aqueous and non-aqueous environments. Designed for compatibility across a broad pH spectrum and temperature range, 5055 is particularly valuable in high-shear applications such as textile dyeing, metalworking fluids, and architectural coatings. By ensuring a smooth, defect-free surface finish, it enhances the overall quality of end products. The 5055 model serves as a critical processing aid, optimizing production efficiency by preventing foam-related overflow and pump cavitation in demanding industrial workflows where surface tension integrity is absolutely paramount.
