Product Overview
SAG™ 638 Antifoam Emulsion from Momentive Performance Materials is a premium solution for controlling foam in a wide range of aqueous systems. Engineered for general-purpose foam management, SAG 638 delivers exceptional foam knockdown and sustained performance even in challenging conditions. Its formulation allows for effective foam suppression at very low concentrations, typically between 50-100 ppm, which enhances processing efficiency and maximizes production capacity. The
