Introducing BYK 349 from Wellt
Our product brand: Wellt 349
- BYK-349 significantly lowers surface tension in aqueous systems, enhancing substrate wetting, spreading, and leveling properties across various applications.
- The additive only marginally stabilizes foam, ensuring that recoatability is not negatively impacted.
- Unlike some additives, BYK-349 does not raise surface slip but can be combined with polysiloxanes like BYK-333 if higher slip is required.
- Ideal for use in aqueous coatings, adhesives, printing inks, and maintenance products, particularly in automotive, architectural, industrial, and wood coatings.
- Optimally suited for aqueous systems without organic co-solvents while maintaining compatibility with specific resin combinations like styrene acrylic and acrylic/PU systems.
