BYK-012 is especially recommended as a defoamer in the preparation and application of emulsion paints and plasters within a PVC range of 30-85. The additive is free of silicones and mineral oil, and is especially suitable for VOC-free systems. It exhibits an optimal effect at the lowest dosage, is stable to acids and alkalis, and can be used in the pH range 3-12. BYK-012 can lead to turbidity and seeding in clear coatings.
