Product descriptionSilicone Defoamer QYS4008 is an anhydrous, low-viscosity, readily dispersible and relatively alkali-resistant organomodified antifoam agent with good deaeration characteristics.ApplicationBecause of its structure, QYS4008 can be used for defoaming surfactant-containing formulationsor for foam suppression in processes that use surfactants, with a significant reduction in undesirable secondary effects, such as incompatibility, rapid exhaustion or low alkali resistance.QYS4008 is suitable primarily for the following applications:- Alkaline processes in the textiles industry(bleaching, washing, dyeing, etc.).- Surfactant-containing compositions in which the defoamer is required to be highly compatible, for example, liquid detergents and cleaning agents.ProcessingQYS4008 is usually added to the formulations to be defoamed in amounts of 0.3–1.0% at the end of the product formulation stage. It does not need to be diluted first, and is stirred in gently.QYS4008 usually disperses without the need to apply high shearing forces.In textile processes, QYS4008 is added at the beginning of the process in an amount corresponding to the desired degree of foam suppression. During the course of relatively long processes more may be added if necessary.StorageThe 'Best use before end' date of each batch is shown on the product label.Storage beyond the date specified on the label does not necessarily mean that the product is no longerusable. In this case however, the properties required for the intended use must be checked for qualityassurance reasons.Safety informationDetailed safety information is contained in each Material Safety Data Sheet, which can be obtained from our sales offices.
