Leveling Agents for Water‑borne Systems: Control Craters, Orange‑peel and Surface Smoothness

Polyether‑modified siloxane leveling agents eliminate craters, orange‑peel defects for water‑borne coating & ink. Ruico alternatives for BYK‑333, TEGO 410, TEGO450.

Surface appearance defects including craters, orange‑peel and uneven gloss greatly affect final product quality of water‑borne coatings and printing inks. Properly selected leveling agents help to homogenize surface tension and deliver smooth film appearance.

Polyether‑modified siloxane represents the mainstream leveling‑agent technology for water‑borne formulas. Ruico’s 100%‑active leveling‑agent series includes:

• RF‑A141: alternative for TEGO 410
• RF‑A143: drop‑in replacement for BYK‑333
• RF‑A145: equivalent to TEGO 450

Formulators need to balance three key factors: surface‑smoothing performance, foam impact and inter‑coat adhesion. Excessive siloxane‑type leveling agent may to over‑slippage and poor re‑coating performance. Therefore gradient‑dosage testing is strongly advised.
