Why Do We Need Conductive Carbon Paste Defoaming Machine

Membrane Switches & Buttons

Carbon paste is printed to form conductive contacts for membrane switches and buttons. Air bubbles and agglomerates create pinholes and uneven thickness in carbon films, resulting in contact resistance drift and button failure.

Carbon Film Resistors

Printing for carbon film resistors and heating sheets requires stable resistance values. Agglomeration and bubbles cause resistance dispersion and poor batch consistency.

EMI Shielding

EMI shielding carbon paste demands continuous and dense coatings. Bubbles and pinholes break the continuity of shielding layers and weaken shielding performance.

✨ Traditional Dilemma: Carbon black features large specific surface area and tends to agglomerate severely. Manual stirring brings air entrapment and agglomerates, leading to unstable resistance of carbon films. Vacuum defoaming with strong dispersion is required

Why Choose SIENOX Carbon Paste Defoaming Solution

Break Carbon Black Agglomerates

Rotational shear breaks up agglomerates of carbon black and graphite for continuous and uniform carbon films with consistent resistance.

Vacuum Defoaming

Trapped air generated during stirring is removed synchronously to reduce pinholes in carbon films and deliver more reliable shielding and conductivity.

Reproducible Batches

100 groups of formula storage ensures stable carbon film resistance across batches. Smooth process scale-up from lab samples to mass production.

Precautions for Use

NotesOperation Instructions
Dispersion TimeCarbon black has a large specific surface area. Control vacuum stirring duration and shear strength to balance dispersion and defoaming.
Loading & Rotation SpeedMatch loading volume and rotation speed for high-viscosity carbon paste to prevent carbon black sedimentation and re-agglomeration.
Slow Pressure ReliefRelease pressure slowly after defoaming to avoid re-foaming and splashing of paste.
Prompt PrintingPrint promptly after defoaming and dispersion to prevent re-agglomeration of carbon black upon standing.
