defoamer for PU adhesive

The defoamer for PU adhesive series helps adhesive manufacturers maintain clean and stable bonding films. Designed for high-viscosity and reactive PU systems, it eliminates microfoam during mixing and application, ensuring smooth appearance and strong adhesion. It enhances production efficiency and reduces rework costs caused by trapped air. With silicone and non-silicone options, the defoamer provides compatibility across different PU adhesive chemistries. It’s ideal for OEMs and industrial users seeking consistent performance and clean, uniform surfaces.

defoamer for PU adhesive

The defoamer for PU adhesive acts through rapid spreading and localized surface tension reduction, collapsing entrapped bubbles without disturbing curing reactions. It stabilizes viscosity and improves film homogeneity, resulting in stronger, defect-free bonds. Suitable for moisture-cured and hot-melt PU adhesives, it maintains gloss, adhesion, and aging resistance under varying temperature and humidity conditions.
