QuantaSperse NBB is a nanotechnology-derived foam knock-down additive (Antifoam) for industrial applications. In industrial processes, foams pose serious problems. They prevent the efficient filling of containers and reduce processes efficiencies/recoveries. De-foaming agents such as QuantaSperse NBB are used to reduce or hinder the formation of foam in industrial processes. QuantaSperse NBB is a water dispersible (ultrafine) innovative antifoam additive used in processes where quick knock-down antifoam is required.
