Why OCA Optically Clear Adhesive Defoaming Machine Is Needed

Bubbles in Full Lamination

Bubbles and white spots after OCA full lamination of mobile phones and tablets directly affect display performance, and rework cost for screen-grade products is extremely high.

High Transparency of Optically Clear Adhesive

Optically clear adhesives are highly sensitive to microbubbles and impurities. Tiny bubbles are clearly visible when the screen is lit, resulting in heavy yield loss.

Touch Lamination

Lamination of touch screens and cover glass requires uniform and void-free adhesive layers. Bubbles will also impair touch sensitivity and appearance consistency.

✨ Traditional Dilemma: Even tiny bubbles in optically clear adhesive will lead to full-screen rework. High-cleanliness vacuum defoaming is required to completely remove bubbles before lamination.

Why Choose SIENOX Optically Clear Adhesive Defoaming Solution

Void-free Lamination

Vacuum removal of microbubbles reduces bubbles and white spots after OCA full lamination for clear and bright display.

Clean Non-contact Operation

No paddles or impurities introduced, keeping adhesive clean and preventing white spots and contamination.

Yield Improvement

Adequate defoaming cuts screen rework rate and delivers more stable yield for optical lamination.

Equipment Supporting Description

SIENOX AB adhesive defoaming solution can be matched with other equipment to build a complete potting process chain: 

Integrated Mixing & Defoaming: MIX series mixers blend AB adhesives and perform synchronous defoaming under vacuum, accomplishing mixing and bubble removal within one single process. 

Temperature-controlled Defoaming: WK series temperature-controlled defoamers work at preset temperatures. It is suitable for high-viscosity AB adhesives, which can be heated to lower viscosity for higher defoaming efficiency. 

Defoaming & Dispensing Linkage: Directly connect to SIE-301/302/303 dispensers for potting after defoaming to avoid new bubbles generated during material transfer. 

Pressurized Fine Defoaming: For applications requiring superior defoaming rate, transfer materials to RX pressurized defoamer for secondary fine defoaming after vacuum mixing to achieve better bubble removal performance.

  • 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

PrecautionsOperating Instructions
Clean EnvironmentPerform defoaming and material transfer in a clean environment to avoid white spots and impurities caused by dust.
Light-shielded OperationKeep UV curable optically clear adhesive away from light to prevent premature curing.
Slow Pressure ReliefRelease pressure slowly after defoaming to prevent re-foaming and hazing of optically clear adhesive.
Timely LaminationComplete lamination promptly after defoaming to avoid re-entrapment of air bubbles.

* Internal laboratory test data. Actual results depend on optically clear adhesive formulation and lamination process. Contact sales for real customer cases.
