| Properties: | SCHWEGO foam 8325 is a liquid, very effective defoaming additive for emulsion paints. Particularly for those based on styrene/butadiene latex and acrylic copolymers. SCHWEGO foam 8325 is readily emulsifiable in water. | |
| Applications: | SCHWEGO foam 8325 can be used in emulsion paints, water-based coatings, silicate paints, adhesives and plasters. | |
| Technical data: (Guide values) |
Appearance : light yellow, whitish cloudy liquid Density (ISO 2811-1) : 0,86 g/cm³ Flash point (ISO 1523) : >100°C Active matter : 100 % |

| Processing: | SCHWEGO foam 8325 can be used as supplied or emulsified with 3-4 times the quantity of water. Depending on system it may be advantageous to add 2/3 of the defoamer quantity during the dispersion of the pigment and 1/3 to the emulsion, provided it is homogeneously distributed. The optimum dosage is 0.1 - 0.3 % SCHWEGO foam 8325, calculated on total system. The dosage may be increased up to 1.0 %. SCHWEGO foam 8325 is incorporated to the mill base. Thus, a good distribution is ensured and good defoaming is achieved when applied. | |
| Storage: | Do not store SCHWEGO foam 8325 at temperatures below 5 °C and above 30 °C. Stir it up befor use. Keep it in a cool, well-ventilated place. As the viscosity of the product increases at low temperatures it is recommended to store SCHWEGO foam 8325 at ambient temperature in order to simplify subsequent processing. | |
| Subject to appropriate storage, the described properties of SCHWEGO foam 8325 remain stable for at least 18 month, provided the original container is closed after use. | ||
