Why Do We Need Acrylic Coating Defoaming Machine

Industrial Acrylic Topcoat

Air 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 Dispersion

Color 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 Coatings

Acrylic 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 & Dispersion

Vacuum stirring achieves defoaming and breaks pigment agglomerates at the same time for uniform color development and consistent gloss of pigmented coatings.

Improved Leveling

Bubble removal delivers uniform film leveling, fewer craters and pinholes for cleaner surface appearance.

Flexible Color Change

Frequent 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

NotesOperation Instructions
Vacuum LevelControl vacuum level for solvent-based acrylic paints to prevent excessive solvent volatilization which alters viscosity.
Moderate Vacuum for Water-based PaintsApply moderate vacuum for water-based acrylic paints to avoid impairing wetting and leveling performance.
Slow Pressure ReliefRelease pressure slowly after defoaming to prevent paint re-foaming.
Timely ApplicationSpray the paint as soon as possible after defoaming to prevent pigment re-sedimentation or air re-entrapment.
