Defoamer for Waterborne Systems
In StockSample available
Key Features
- Silicone-free — no surface contamination
- Effective at low dosage 0.05-0.3%
- Compatible with anionic and nonionic systems
- Does not affect fiber-matrix adhesion
Defoamer for waterborne composite systems including glass fiber sizing baths, aqueous silane coupling agent solutions, and water-based binder systems. Silicone-free grades prevent surface contamination in fiber treatment operations. Effective at low dosage (0.05-0.3% by weight), compatible with anionic and nonionic surfactants. Does not affect fiber-matrix interfacial adhesion.
