Usage:
- Add AT-670 into the foaming media and make sure it is well dispersed.
- For the high temperature foaming system (>60°C), better to add the antifoam before 60°C with good mixing
- Based on the viscosity of various foaming systems, as well as temperature and other ingredients, the dosage can be 30-200ppm to get the acceptable performance. But for some industry like fermentation industry, the dosage can be up to 2-5‰.
Use:
- Textile printing paste, bleaching and dyeing
- Waste water treatment, paper making
- Industry washing, adhesive production
