Why Do You Need an AB Glue Defoaming Machine?

Bubbles entrapped during mixing greatly impair potting quality

Electronic Component Potting Industry

Electronic components such as power modules, transformers and sensors are commonly protected by epoxy AB‑glue potting. Bubbles form voids inside potting layers, causing uneven electrical insulation. Breakdown tends to occur at bubble positions under high‑voltage conditions, resulting in direct component scrapping.

 LED Lighting Industry
              

Transparent or white AB glue is widely used for potting LED strips, modules and driving power supplies. Bubbles are highly visible in transparent glue layers, directly damaging appearance and light‑efficiency uniformity. Worse still, poor heat dissipation at bubble positions drastically shortens LED bead service life. Properly debubbled potting layers deliver uniform transparency, consistent luminous efficiency and reliable heat dissipation.

Automotive Electronics Industry 

 Potting requirements are stricter for vehicle‑mounted ECUs, wire‑harness connectors, sensors and other parts. Cracks and liquid ingress easily emerge around bubbles under vibration, temperature cycling and humid‑hot conditions. Automotive‑grade products demand strict potting compactness for every unit in mass production. Stirring‑vacuum defoaming machines match production‑line tact time to guarantee consistent potting quality for each batch.        

✨ Traditional Dilemma: After manual stirring of AB glue, pour it into a container and let it stand for half an hour. Though no bubbles appear on the surface, numerous tiny holes turn up once the potted part is cured and cut open. Bubbles inside high‑viscosity AB glue cannot escape merely by vacuum chamber pumping. Even if defoaming is finished, new bubbles get entrapped again during potting. What you need is not more expensive glue, but a stirring‑vacuum defoaming solution that completes mixing and defoaming simultaneously.

Why Choose SIENOX AB‑Glue Defoaming Solution

Solve Core Challenges of AB‑Glue Mixing and Defoaming

Simultaneous Mixing and Defoaming

The biggest pain point of AB glue is bubbles entrapped during mixing. SIENOX MIX‑series stirring‑vacuum defoaming machines blend A and B glue under vacuum atmosphere. Bubbles generated during stirring are extracted synchronously under vacuum. Mixing and defoaming are accomplished in one single process, eliminating separate steps of stirring, material transfer and defoaming. It improves efficiency and prevents new bubbles caused by secondary material transfer.

Full‑phase Application Coverage

C‑series centrifugal defoaming machines (0‑12mL) for lab small‑sample verification for efficient defoaming of several‑milliliter AB‑glue samples; ZK‑series vacuum defoaming machines (50‑500mL) for pilot scale‑up; MIX‑series stirring‑vacuum defoaming machines (50mL‑20L) for mass production. Process parameters can be smoothly scaled up from R&D formula validation to batch potting.

For Thin to Paste‑Like Adhesives

SIENOX equipment series covers full viscosity range, from low‑viscosity epoxy AB glue (good fluidity, handled by centrifugal defoaming) to medium‑high‑viscosity thermal‑conductive AB glue (paste‑type, requiring combined stirring and vacuum). Corresponding defoaming modes are matched for different viscosities to guarantee satisfactory defoaming performance.

✨ MIX15LWK meets heavy‑duty temperature‑controlled mass production and high‑viscosity defoaming demands for temperature‑sensitive materials including new energy, semiconductors, adhesives and advanced materials.

Equipment Supporting Instructions

SIENOX AB‑glue defoaming solution can cooperate with other equipment to form a complete potting process chain

SIENOX AB‑glue defoaming solution can cooperate with other equipment to form a complete potting process chain: 

Integrated stirring & defoaming: MIX‑series stirring defoaming machines mix AB glue and perform synchronous defoaming under vacuum, finishing mixing and debubbling in one procedure. 

Temperature‑controlled defoaming: WK‑series temperature‑controlled defoaming machines conduct defoaming at set temperatures. Suitable for high‑viscosity AB glue to reduce viscosity by heating for higher defoaming efficiency. 

Defoaming & dispensing linkage: Connect directly to SIE‑301/302/303 dispensing machines for potting after defoaming, reducing new bubbles introduced by intermediate transfer steps. 

Pressurized fine defoaming: For scenarios requiring high defoaming rate, perform secondary fine defoaming with RX pressurized defoaming machine after stirring‑vacuum defoaming for higher defoaming efficiency.

  • 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.

Operating Precautions

Material Defoaming Effect Comparison Before & After

Material TypePre‑treatment Status
Silver PasteWeigh A/B components of AB glue accurately by ratio before mixing and defoaming. Incorrect ratio will impair curing performance.
Stirring SpeedControl stirring speed during vacuum stirring‑defoaming. Excessively high speed may generate new vortex bubbles.
Time ControlComplete defoaming and dispensing within pot‑life after AB‑glue mixing. Adhesive will thicken and cure beyond time limit.
Vacuum DefoamingRelease pressure slowly after vacuum defoaming to prevent adhesive foaming caused by rapid decompression.
Temperature ControlFor higher efficiency, heat high‑viscosity AB glue to 40‑60℃ properly to reduce viscosity before defoaming.
