Why Silicone Defoaming Machine Is Required

Transparent Potting Silicone Industry

Bubbles and white spots in transparent or white potting silicone are highly visible under transmitted light, which directly affects appearance and light transmittance. Bubbles also reduce sealing and insulation reliability. Properly defoamed silicone features clear and uniform texture.

Thermal Conductive Grease & Gel Industry

Thermal conductive grease and thermal conductive gel contain large amounts of thermal conductive fillers with high viscosity and tend to agglomerate. Trapped bubbles and voids increase thermal resistance, resulting in poor heat dissipation of chips and shortened service life. Vacuum mixing enables simultaneous defoaming and deagglomeration of fillers.

Addition-cured Silicone Rubber Industry

Addition-cured (platinum-catalyzed) silicone rubber is sensitive to impurities. Contact with sulfur, phosphorus or amines may cause catalyst poisoning and failed curing. Meanwhile, air entrapment during mixing creates pores inside vulcanized parts. Non-contact vacuum defoaming provides higher safety.

✨ Traditional Dilemma: Air entrapment during manual mixing and the difficulty for bubbles to rise in high-viscosity silicone; addition-cured adhesives may fail to cure once contaminated. Hence, a vacuum, non-contact and reproducible defoaming method is required.

Why Choose SIENOX Silicone Defoaming Solution

Vacuum Elimination of Microbubbles

Negative pressure drives microbubbles within transparent silicone to rise, delivering crystal clear adhesive surface without white spots and meeting the requirements of high-transparency potting.

Shear Dispersion of Fillers

Rotational shear breaks up agglomerates of thermal conductive fillers. After void removal, fillers form tighter contact for improved thermal conductivity consistency.

Non-contact & Contamination-free

It will not damage the platinum catalyst system and cause no cross-contamination. 100 recipe storage slots support stable and reproducible silicone processes for mass production.

  • 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
Contamination PreventionTools and containers for addition-cured silicone shall not come into contact with substances containing sulfur, phosphorus or amines to prevent catalyst poisoning and curing failure.
Heating for Viscosity ReductionHigh-viscosity thermal grease can be moderately heated to reduce viscosity before defoaming for higher defoaming efficiency.
Slow Pressure ReliefRelease pressure slowly after defoaming and before opening the lid to avoid bubble reformation on adhesive surface.
Uniform MixingFor filler-loaded silicone, match loading volume with rotation speed to prevent filler sedimentation and uneven dispersion.
