Epoxy Coating Defoaming Machine


Resolve pinholes and bubbles in epoxy coatings · Dense coating films, void-free anti-corrosion layers

Vacuum stirring & defoaming + Pigment and filler dispersion + Viscosity reduction and defoaming for high-build coatings

SIENOX epoxy coating defoaming solution addresses entrapped air bubbles and pigment agglomeration generated during stirring and spraying of epoxy zinc-rich primers, epoxy floor paints and anti-corrosion topcoats. Synchronous stirring and defoaming under vacuum produces dense coating films with favorable leveling performance and effectively reduces pinholes, craters and voids within anti-corrosion layers.

Why Do We Need Epoxy Coating Defoaming Machine

Epoxy Anti-corrosion Coatings

Anti-corrosion paints such as epoxy zinc-rich and epoxy coal tar pitch for steel structures, pipelines and containers contain plenty of pigments and fillers. Air entrapment during stirring and spraying leads to pinholes and voids after curing, damaging the dense anti-corrosion layer.

Epoxy Floor Paint

Epoxy floor intermediate and top coats feature thick film thickness. Air trapped during stirring and troweling creates surface pinholes and pits after curing, impairing floor smoothness and wear resistance.

High-build Epoxy Coating

High-build, high-solid epoxy paints have high viscosity and abundant fillers. Bubbles hardly float up, frequently causing blisters and craters after spraying or roller coating with high recoating cost.

✨ Traditional Dilemma: Manual stirring of high-filler high-build coatings entraps air, resulting in pinholes and voids after curing. Sanding and recoating consume time and materials. Vacuum stirring & defoaming with filler dispersion is required.

Why Choose SIENOX Epoxy Coating Defoaming Solution

Simultaneous Defoaming & Dispersion

Stir and defoam under vacuum while breaking up pigment and filler agglomerates for dense coating films and uniform color.

Suitable for High-build Coatings

Heat high-viscosity high-build coatings to reduce viscosity before vacuum stirring, enabling bubbles to rise easily and improving leveling and film formation.

Full-stage Coverage

C/ZK series supports lab color matching, MIX series for scale-up mass production. Formulas can be replicated from sampling to production line.

✨ 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
Accurate Mix RatioWeigh the two-component epoxy coating accurately before mixing and defoaming. Incorrect ratio will affect film formation.
Heating for Viscosity ReductionHeat high-viscosity high-build coating appropriately to reduce viscosity prior to defoaming to improve defoaming and leveling performance.
Standing Before CoatingAllow the material to stand for several minutes after defoaming before spraying / roller coating to reduce pinholes.
Slow Pressure ReliefRelease pressure slowly after defoaming to prevent re-foaming and splashing of coating material.

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