BYK-061 – Silicone defoamer for solvent-borne and solvent-free systems with outstanding stability even at low temperatures
Solvent-free systems based on epoxy or PUR resins, which are used in floor coatings as a binder, for example, require a fast and efficient air release during the application, since these formulations generally have a greater viscosity. However, the same applies to solvent-borne coatings, e.g. alkyd systems, to obtain a defect-free surface after the application. If the additive is stored or processed at low temperatures, the requirements for the performance of the defoamer are even higher. The new BYK-061 meets all of these expectations in full. The additive offers fast and spontaneous defoaming. BYK-061 shows high stability and performance even at low temperatures. A further advantage is the achievement of very good results even at a very low dosage.
27.08.2019 - BYK-1707, BYK-3750, BYK-3752, BYK-3754, BYK-3761, BYK-3762, BYK-3764, BYK-3770 and BYK-3771
The European Chemicals Agency (ECHA) added the cyclic siloxanes D4, D5 and D6 to the EU REACH candidates list for “Substances of Very High Concern” (SVHC). BYK is obliged to show this information on the EU safety data sheet (section 15) if at least one of these substances is present in a BYK additive in a quantity of 0.1 % or greater. It means that when the affected additives are used in coatings, plastics, printing inks or adhesives, and in the various end applications, increased demands on the protection of health and safety can be required. To keep the use of the silicone additives in question as simple and uncomplicated as possible, BYK has purified well-known standard additives and is now offering versions of these products with a low cyclic siloxanes content. They are SVHC label-free and can be dosed and applied in the same way as the standard versions, hence there is no need to change the formulation.
