Acrylic Coating Defoaming Machine
Resolve bubbles and craters of acrylic coatings · Uniform color paint and consistent leveling
Vacuum defoaming + Break up pigment agglomerates + Uniform color development of pigmented coatings
SIENOX acrylic coating defoaming solution addresses air entrapment and pigment agglomeration issues during stirring for acrylic color paints containing titanium dioxide and other pigments. It enables stirring, dispersion and defoaming simultaneously under vacuum, reducing mottling and craters of color paints for more consistent gloss and leveling performance.
✓ CE certification ✓ ISO9001 Quality Management System ✓ RoHS compliance ✓ Custom voltage available (110V/220V)
Why Do We Need Acrylic Coating Defoaming Machine
Industrial Acrylic TopcoatAir entrapment occurs during stirring and spraying of acrylic color paints for machinery and metal parts. After curing, craters and pinholes appear with uneven gloss, affecting appearance consistency. | Uneven Pigment DispersionColor paints contain titanium dioxide and chromatic pigments. Pigment agglomeration causes mottling and hue fluctuation, leading to color inconsistency within the same batch of paint. | Plastic & Toy CoatingsAcrylic paints for plastic components and toys require bubble-free surfaces. Bubbles and craters are especially noticeable on light-colored high-gloss finishes. |
✨ Traditional Dilemma: Pigmented coatings suffer from both entrapped air and pigment agglomeration, resulting in mottling and craters after spraying. Repeated paint mixing and rework lead to material waste. Simultaneous defoaming and dispersion is required.
Why Choose SIENOX Acrylic Coating Defoaming Solution
Integrated Defoaming & DispersionVacuum stirring achieves defoaming and breaks pigment agglomerates at the same time for uniform color development and consistent gloss of pigmented coatings. | Improved LevelingBubble removal delivers uniform film leveling, fewer craters and pinholes for cleaner surface appearance. | Flexible Color ChangeFrequent color switching for multi-color orders. C/ZK series supports fast color matching and defoaming, while MIX series scales up for mass production. |
✨ The MIX series is the ideal defoaming equipment for offset printing inks 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 |
| Vacuum Level | Control vacuum level for solvent-based acrylic paints to prevent excessive solvent volatilization which alters viscosity. |
| Moderate Vacuum for Water-based Paints | Apply moderate vacuum for water-based acrylic paints to avoid impairing wetting and leveling performance. |
| Slow Pressure Relief | Release pressure slowly after defoaming to prevent paint re-foaming. |
| Timely Application | Spray the paint as soon as possible after defoaming to prevent pigment re-sedimentation or air re-entrapment. |
