Improvement of wettability with BYK-3565 additive
Water droplets are dropped on two automotive mid-coating panels. One does not contain a surface modifier. The other contains BYK-3565. Due to the increase in surface free energy from BYK-3565, the water droplet spreads significantly. After the water is dropped, the contact angle rises to 60 degrees for both, but due to the interaction between the water and the panel surface, the system with BYK-3565 retains the water droplet.

Wettability spreading of water on PVC Leneta foil. Comparison of BYK-333 and BYK-346
Water droplets are dropped on two PVC foils. The wettability of the water droplets is poor and does not spread. Two types of silicone-based additives (20 µl) are added to the water droplets. BYK-333 and BYK-346. The silicone surfactant BYK-346 is more active than the polymer-type silicone additive BYK-333, resulting in greater expansion and spreading of the water droplets.
Improvement of wettability by adding BYK-3565
Water droplets are dropped on two automotive mid-coating panels. One does not contain a surface adjuster. The other has BYK-3565 added. The surface free energy increases significantly with BYK-3565, causing the water droplets to spread widely. After the water is dropped, the contact angle rises to 60 degrees for both, but due to the interaction between the water and the panel surface, the system with BYK-3565 retains the water droplets.
Wetting spread of water on PVC Leneta foil. Comparison between BYK-333 and BYK-346
Water droplets are dropped on two PVC vinyl foils. The wettability of the droplets is poor and does not spread. Two types of silicone-based additives (20 µl) are added to the droplets. BYK-333 (left) and BYK-346 (right). The silicone surfactant BYK-346 is more active than the polymer-type silicone additive BYK-333, resulting in greater expansion and spreading of the water droplets.
