Why Do We Need UV Curable Coating Defoaming Machine

UV Wood Coating

High-gloss and high-transparency UV paints for furniture and flooring. Bubbles before curing form pinholes and fish eyes on the coating surface, ruining the high-gloss finish.

Shear-sensitive UV System

UV coatings are sensitive to shear heat. Conventional high-speed stirring generates heat, causing premature thickening and reaction of coatings. Coating performance is compromised before defoaming is finished.

3C & Paper Varnishing

UV coatings for 3C casings and paper UV varnishing require high gloss with zero defects. Pinholes and craters will be directly rejected by downstream customers.

✨ Traditional dilemma: Conventional stirring generates heat and causes premature thickening of UV materials. The material thickens before defoaming is completed. Vacuum defoaming with low temperature, low shear and light shielding is required.

Why Choose SIENOX UV Curable Coating Defoaming Solution

Low Shear & Low Heat Generation

Non-contact low-speed vacuum stirring produces minimal heat, preventing premature curing or thickening of UV coatings.

Complete Microbubble Removal

Negative pressure of −98 kPa forces microbubbles in highly transparent UV materials to rise, achieving high-gloss coatings free of pinholes.

Light-shielding & Reproducible Process

Full light-shielding operation. Supports storage of 100 formula recipes for stable and replicable mass UV coating processes.

✨ 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
Light-shielding OperationKeep light out during batching, defoaming and transferring to prevent premature curing of UV coatings.
Low-speed OperationLow-speed stirring is recommended to reduce shear heat and avoid premature thickening of materials.
Vacuum DurationControl vacuum time to prevent excessive volatilization of active monomers which impairs coating performance.
Slow Pressure ReliefRelease pressure slowly after defoaming to avoid re-foaming and fogging of coating materials.

* Internal laboratory test data. Actual results vary with coating formula and construction process. Contact sales for real customer cases.
