Add defoamer after foam generation as foam suppression component. Typical dosage ranges from 10 to 1000 PPM, with optimal quantity determined by customer testing based on specific conditions.
- Can be used directly or after dilution
- For direct use: add to foaming system with thorough mixing and dispersion
- For dilution: DO NOT add water directly to prevent layering and demulsification
- Formulated with polysiloxane, modified polysiloxane, silicone resin, white carbon black, dispersing agent and stabilizer
- Maintains effective foam elimination and suppression at low concentrations
- Excellent foam suppression performance
- Easily disperses in water
- Good compatibility with foaming media
- Helps prevent microbial growth
