Project Description

Waterborne Defoamers for Paints & Coatings | INVINO®  

Foam in waterborne coatings can cause a range of issues, including surface defects, poor film formation, and unpredictable finish. Defoamers are essential for achieving a smooth, consistent film and maintaining high-quality appearance. Excess foam can also increase production time and waste, making foam control a crucial step in formulating waterborne paints, latex paints, and inks.

INVINO® provides high-performance waterborne defoamers that effectively address these challenges, ensuring smooth application, excellent coverage, and enhanced durability.

Key Benefits of Waterborne Defoamers

  • Surface Quality: Reduces fish eyes, pinholes, and orange peel to achieve a smooth and glossy finish.

  • Enhanced Application: Improves flow and leveling to ensure even coverage with fewer defects.

  • Cost Efficiency: Achieves effective foam control at low dosages, saving both time and material costs.

  • Compatibility: Suitable for latex paints, acrylic emulsions, inks, and other waterborne formulations.

  • Regulatory Compliance: Meets VOC and eco-friendly standards, making it ideal for green chemistry and sustainable production.

Frequently Asked Questions (FAQ)

Q: Will the defoamer cause surface defects like cratering or "fisheyes"?
Compatibility is key. For high-gloss or clear coats (varnishes), we recommend our **Mineral Oil-Free** or **Modified Polysiloxane** series. They offer the perfect balance between defoaming power and compatibility, ensuring a defect-free, smooth leveling without causing surface tension defects.
Q: Should I add the defoamer during the Grind or the Let-down stage?
We generally recommend a **split addition** method. Add 50-70% of the stronger defoamer during the **Grind phase** to suppress macro-foam generation. Add the remaining 30-50% of a more compatible defoamer during the **Let-down (finishing) phase** to control micro-foam and ensure long-term stability.
Q: Is it effective for high-pressure Airless Spray applications?
Yes. Airless spraying generates intense shear, creating stubborn micro-foam. Our specifically formulated "Shear Stable" defoamers are designed to break these micro-bubbles instantly upon application, preventing pinholes and ensuring a uniform film build.
Q: Does this defoamer affect the gloss or clarity of the coating?
No, provided the correct grade is selected. For high-gloss enamels and wood coatings, we utilize particle-controlled technology that eliminates foam without causing haze or "gloss reduction" (matting effect).
Q: How does it perform after long-term storage (Shelf Life)?
Our waterborne defoamers are formulated to resist settling and phase separation. They maintain their defoaming efficiency even after months of storage in the paint can, preventing the common issue of "efficiency loss" over time.
