Chemical Composition: A mixture of hydrophobic components in paraffinic mineral oil, containing a small amount of coating-compatible silicone.
Appearance: Liquid.
Solvent: None.
Solid Content: Approximately 97%.
Application Areas:
Latex paints (including gloss and semi-gloss latex paints)
Exterior wall paints
Industrial emulsions
Emulsion-based stuccoes
Adhesives
Production of emulsion binders
Performance Characteristics:
Enhanced Defoaming Efficiency: The addition of a small amount of coating-compatible silicone significantly boosts its ability to break and suppress foam, outperforming conventional mineral oil-based defoamers in fast-paced coating production processes.
Broad Formulation Compatibility: Suitable for latex systems with a pigment volume concentration (PVC) of 20%-70%, adapting to both low-fill (e.g., high-gloss latex paints) and medium-fill (e.g., industrial emulsions) formulations.
Stability and Weather Resistance: Exhibits excellent storage stability—no stratification or sedimentation occurs under normal conditions. It also has good resistance to UV-induced yellowing, ensuring the long-term color stability of exterior wall paints and other outdoor coatings.
Color Neutrality: Does not affect the color acceptance or color development of tinted coating systems, maintaining the accuracy and consistency of the final coating color.
Recommended Dosage: 0.1%-0.5% of the total formulation weight; in exceptional cases, the dosage can be increased to 0.8% (determined by specific formulation requirements and application scenarios).
Usage Method: In most cases, 2/3 of the defoamer is added to the grinding paste (to suppress foam generated during pigment grinding), and 1/3 is added during or after the paint mixing process (to prevent foam formation in the final coating system). This two-stage addition ensures comprehensive foam control throughout the production cycle.
