BYK 1642 is a versatile defoamer additive for aqueous systems. It is VOC-free and contains no silicones or mineral oils. BYK 1642 exhibits optimum performance at the lowest dosage levels. It is stable across a wide pH range and compatible with most formulations. BYK 1642 effectively inhibits foaming during production and application. It has a spontaneous defoaming effect and prevents microfoam formation. BYK 1642 provides anti-foaming benefits without affecting other properties of the final product. It can be added at any stage of production and processing. BYK 1642 is suitable for use in projects requiring low VOC emissions and is a sustainable alternative to traditional defoamers.
