Water-based Coating Defoaming Machine
Resolve foam and pinholes of water-based coatings · No defoamer added, full paint film
Physical vacuum defoaming without defoamers + Preserve adhesion of water-based system + Flexible color change
SIENOX water-based coating defoaming solution addresses the easy foaming problem of water-based industrial paints, water-based wood coatings and architectural coatings containing surfactants. Bubbles are removed by physical vacuum treatment without adding defoamers to prevent damage to paint film adhesion, resulting in plump paint film and fewer pinholes.
✓ CE certification ✓ ISO9001 Quality Management System ✓ RoHS compliance ✓ Custom voltage available (110V/220V)
Why Do We Need Water-based Coating Defoaming Machine
Water-based Industrial CoatingsWater-based industrial coatings contain surfactants and tend to foam easily after stirring and spraying. Pinholes, craters and fish eyes occur during roller coating and spraying, impairing the appearance and protection of metal workpieces. | Water-based Wood CoatingsBubbles and pinholes are prominent on light-colored paint films after film formation of water-based wood coatings. Excessive defoamers will hurt coating adhesion and water resistance. | Architectural Exterior CoatingsWater-based exterior wall paints and real stone paints contain pigments and fillers. Air is entrapped during stirring and construction, leading to pinholes and mottling on coatings and weakening decorative performance and weather resistance. |
✨ Traditional dilemma: Adding defoamers to suppress foam will impair coating adhesion and water resistance. Frequent color changes with manual stirring inevitably entrap air. Physical vacuum defoaming is required.
Why Choose SIENOX Water-based Coating Defoaming Solution
No Defoamers AddedPure physical vacuum defoaming without adding defoamers to preserve adhesion and water resistance of water-based paint films. | Full Paint FilmBubble removal enables smooth and full paint film, fewer pinholes and craters for cleaner appearance. | Flexible Color ChangeFrequent color switching for multi-color orders. C/ZK series support fast color mixing and defoaming, while MIX series for mass production scaling. |
✨ The MIX series is the ideal defoaming equipment for offset ink from color matching to bulk ink supply.

How does the stirring and defoaming machine work?
The SIENOX stirring and defoaming machine performs defoaming through centrifugal force at revolution and stirring through shear force formed by revolution and rotation,
Assisted by a vacuum pump to extract gas and achieve a vacuum state, removing nanoscale tiny bubbles. No contact with materials, no secondary pollution, and no secondary waste.
-
What is the function of a defoaming machine?
A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.

Precautions for Use
| Notes | Operation Instructions |
| Moderate Vacuum | Apply moderate vacuum for water-based paint defoaming. Excessive degassing shall be avoided to prevent adverse effects on wetting, leveling and film formation. |
| Slow Pressure Relief | Release pressure slowly after defoaming to prevent foam re-entering and paint splashing. |
| No Defoamer Added | Rely primarily on vacuum defoaming. Extra defoamers should be avoided to prevent deterioration of adhesion and water resistance. |
| Timely Construction | Start construction as soon as possible after defoaming to avoid air re-entrapment or pigment sedimentation during standing. |
