BYK-3456 is a fluorine free, silicone containing additive active at the interface to the substrate ànd the surface at the same time.
Special Features and Benefits:
Using BYK-3456 can greatly reduce the static and dynamic surface tension, which results in a significant improvement in substrate wetting and leveling. BYK-3456 also enables difficult substrates such as wood, which have porous and uneven surfaces, to be wetted. The additive does not stabilize foam, has no negative impact on recoatability, and does not increase surface slip. Coating defects such as “picture framing” and “fish eyes” are considerably reduced. As a result of its high compatibility with various binder systems, even with a low proportion of co-solvent, BYK-3456 is ideally suited for use in modern coating systems.
