Key Advantages
1. Effectively lowers surface tension, enhances spreading performance over various hard‑to‑wet substrates.
2. Matches medium‑to‑high‑polarity resins with prominent crater‑suppression effect.
3. Controllable foaming behaviour, compatible with spray‑coating and roll‑coating application methods.
4. Good compatibility with most acrylic, polyurethane and epoxy resins.
5. Can be used synergistically with defoamers to optimise manufacturing processes.
