1. Basic Information

• Product Name: Cognis Defoamer 134
• Packaging Specification: 172 kg/drum
• Chemical Composition: Non-ionic surfactant system. This component is mild in nature, featuring good compatibility with various water-based systems and no easy damage to the original properties of products like coatings.
• Product Category: Industrial defoamer

2. Product Characteristics

1. Efficient Defoaming: It can quickly eliminate bubbles in systems such as latex paints and emulsion polymers, effectively avoiding coating defects like pinholes and pockmarks caused by residual bubbles, and improving the appearance quality of products.
2. Long-lasting Anti-foaming: During the production, storage and use of adhesives, pressure-sensitive adhesives and other products, it has the ability to inhibit bubble generation for a long time, ensuring stable product performance.
3. Good Compatibility: For water-based systems like water-based wood coatings, it will not cause adverse phenomena such as delamination and demulsification. After addition, the uniformity and stability of the system can still be maintained.
4. Effective at Low Dosage: Only a small amount of Cognis Defoamer 134 needs to be added to achieve the ideal defoaming and anti-foaming effects, which helps control production costs while ensuring product quality.

3. Application Fields

1. Latex Paints: Suitable for the production process of various interior and exterior latex paints, ensuring that a smooth and flat paint film is formed after the latex paint is applied.
2. Emulsion Polymers: During the emulsion polymerization reaction and the subsequent processing and use of emulsion products, it can effectively control foam problems and ensure the smooth progress of production.
3. Adhesives and Pressure-sensitive Adhesives: It can help adhesives and pressure-sensitive adhesives maintain good fluidity and coatability during manufacturing, coating and other processes, avoiding problems such as poor bonding effect caused by bubbles.
4. Water-based Wood Coatings: When applied to water-based wood coatings, it can improve the gloss and fullness of the paint film, making the decorative effect of the wood surface better.

4. Usage Methods

• Addition Method: It can be directly added during the stirring and dispersion stage of the production process, or added after the system mixing is completed. However, in both cases, sufficient stirring and uniform mixing must be ensured to exert the best defoaming effect.
• Recommended Dosage: The general addition amount is 0.1% - 0.5% of the total system volume. In actual use, the most suitable addition amount can be determined through small-scale tests according to the specific product formula and foam conditions.

5. Storage and Transportation

• Storage Conditions: It should be stored in a cool, dry and ventilated warehouse, avoiding direct sunlight and high-temperature environments. The storage temperature is recommended to be controlled at 5 - 35℃. Keep the package sealed to prevent the product from absorbing moisture, volatilizing or being contaminated.
• Shelf Life: Under the conditions that meet the storage requirements, the shelf life is usually 12 - 24 months.
• Transportation Requirements: It is a non-hazardous chemical and can be transported by road, railway and other conventional means as ordinary goods. However, during transportation, severe collision and inversion should be avoided to prevent package damage.
