1. Basic Information

• Product Name: FoamStar ST 2280 Defoamer
• Packaging Specification: 20 kg/drum
• Main Ingredient: Modified polydimethylsiloxane, whose compatibility with water-based systems and defoaming efficiency have been enhanced through molecular structure optimization.

2. Product Characteristics

1. Broad-Spectrum Defoaming Ability:
   • For various water-based media such as water-based coatings, water-based color pastes, acrylic systems, PVC coatings, alkyd systems, and polyurethane systems, it can quickly break down existing bubbles and continuously inhibit foam regeneration during production, storage, and application stages. This prevents coating defects like pinholes and craters.
2. Excellent System Adaptability:
   • It has good compatibility with mainstream film-forming substances such as water-based acrylic resins, PVC emulsions, alkyd resins, and polyurethane emulsions. After addition, it does not affect the basic properties of the system (e.g., gloss, viscosity, adhesion) and will not cause phenomena like delamination or demulsification.
3. High Efficiency at Low Dosage:
   • Only 0.1% - 0.5% of the total system volume needs to be added to achieve the ideal defoaming effect. Compared with traditional defoamers, it saves more dosage and reduces production costs.
4. Environmental Friendliness:
   • It contains no solvents or harmful substances, complies with environmental standards, and is suitable for scenarios with high environmental requirements such as interior/exterior architectural coatings and industrial water-based coatings.

3. Application Fields

1. Water-Based Architectural Coatings:
   • Suitable for interior/exterior wall latex paints, matte/high-gloss coatings, elastic coatings, etc. It improves the leveling property during construction and ensures a smooth and flat wall coating.
2. Water-Based Industrial Coatings:
   • Can be used in metal anti-corrosion coatings, automotive primers, wood coatings, etc. It eliminates bubbles generated during spraying or roller coating and enhances the protective performance of the coating.
3. Water-Based Color Pastes and Adhesives:
   • Effectively controls foam in the color mixing process of water-based color pastes and the production of adhesives, ensuring uniform color of products and good coating effect.

4. Usage Methods

• Dosage:The recommended dosage is generally 0.1% - 0.5% of the total system volume. The specific dosage needs to be determined through small-scale tests based on the coating formula, foam severity, and process conditions.
• Addition Method:It can be directly added during the grinding and dispersion stages of coating production, or diluted with an appropriate amount of water and slowly added under stirring to ensure uniform dispersion of the defoamer.

5. Storage and Transportation

• Storage Conditions:Store in a cool, dry, and well-ventilated place at 5℃ - 35℃, avoiding direct sunlight and high-temperature environments. Keep the package sealed to prevent moisture absorption or contamination.
• Shelf Life:Under proper storage conditions, the shelf life is 12 - 24 months.
• Transportation Requirements:It is a non-hazardous product and can be transported as ordinary goods. Avoid severe vibration and inversion during transportation.
