Project Description
Waterborne Defoamers for Paints & Coatings | INVINO®
Foam generation within waterborne coatings formulations induces immediate operational limitations, including micro-void surface defects, impaired film formation parameters, and unpredictable gloss consistency boundaries during drawdown. Defoamers are necessary component additions to balance macro-foam collapse during high-speed pigment dispersion milling stages while maintaining long-term chemical persistence during the final let-down phase. Restricting foam volume fractions remains a critical threshold for formulating architectural latex paints, wood coatings, industrial primers, and water-based inks.
INVINO® provides structured non-silicone hydrocarbon compounds and modified organosilicone emulsions calculated for balanced macro-foam knockdown and micro-bubble deaeration. These formulations regulate interfacial surface tension gradients to safeguard substrate wetting parameters, surface flow leveling, and uniform dry film structure.

Key Benefits of Waterborne Defoamers
Reduces surface tension irregularities including fish eyes, pinholes, and orange peel anomalies to achieve a uniform, high-gloss drawdown structure.
Improves wet film film flow and leveling parameters across high-shear grinding lines, ensuring complete coverage with minimal surface macro-defects.
Secures macro-foam suppression boundaries at low dosage metrics (0.1%–0.3% w/w fractions), conserving batch compounding timelines and chemical waste.
Calibrated safe for commercial latex paints, acrylic emulsions, waterborne inks, and continuous architectural polymer resin structures.
Meets dynamic VOC regulations and eco-friendly criteria, acting as non-APEO component blocks for modern green chemistry formulations.
Frequently Asked Questions (FAQ)
Will the defoamer cause surface defects like cratering or "fisheyes"?
A: Incorrect dosing or poor active dispersion can create local surface tension variations, leading to cratering. INVINO® mineral oil formulas are engineered with specific emulsifier balances to optimize compatibility within the acrylic polymer matrix, preventing fish-eye anomalies.
Should I add the defoamer during the Grind or the Let-down stage?
A: We recommend a split-dosing protocol. Add 50% of the calculated amount into the pigment grind stage to control intense foam buildup caused by high mechanical shear. Introduce the remaining 50% during the final let-down blend to ensure long-term persistence in storage.
Is it effective for high-pressure Airless Spray applications?
A: Yes. High-pressure airless atomization creates extreme air entrainment limits. Our high-viscosity compound series, including INVINO-604, retains active structural properties under high shear, maintaining dynamic anti-foaming kinetics inside spray tips.
Does this defoamer affect the gloss or clarity of the coating?
A: Heavy loading of aliphatic hydrocarbons can potentially alter gloss baselines. For clear coats or high-gloss decorative varnishes requiring strict optical transparency, we recommend matching the formulation with INVINO-3100 or INVINO-604 siloxane composites.
How does it perform after long-term storage (Shelf Life)?
A: INVINO® hydrocarbon and siloxane active formulations possess standard chemical stability parameters for 12 months when held within sealed factory boundaries out of direct solar radiation between 5°C and 35°C thresholds.
