Product Introduction

TX-E2 is a single-walled carbon nanotube (SWCNT) pre-dispersed concentrated material independently developed and produced by Shandong Carbon Search. It can be diluted and directly added to various resin systems for use.

This product uses fatty acid glycidyl ester as a carrier and is mainly used as a conductive and antistatic modifying additive for solvent-free epoxy coatings. At an appropriate dosage, it will not adversely affect the color or mechanical properties of the epoxy substrate, and can impart stable conductive/antistatic performance to the system while having little effect on the rheological properties of the matrix.

Core physicochemical & electrical properties

• Conductive properties: Single-walled carbon nanotubes form a continuous conductive network, providing durable and stable conductivity unaffected by ambient humidity, unlike traditional ionic antistatic additives.

• Adjustable resistance range: By adjusting TX-E2 dosage, surface resistance can be tuned across a wide range of 10⁴ ~ 10¹¹ Ω/sq, covering conductive, static dissipative, and antistatic requirements.

• Rheology: Minimal change in epoxy resin viscosity and density, with good compatibility with existing production processes.

• Mechanics: Mechanical strength of the epoxy composite is maintained, with slight improvement in some formulations.

• Color: Enables light-colored and colored epoxy products, overcoming the limitation of carbon black conductive fillers to black products only.

Key advantages

• Wide-range static control: Carbon nanotubes form a uniform conductive network for durable, stable antistatic and conductive performance.

• Mechanical-friendly: Maintains substrate mechanical properties, with possible gains in some formulations.

• Color-compatible: No blackening, enabling light-colored and colored epoxy products.

• Process-compatible: Pre-dispersed concentrate, no complex pretreatment, directly compatible with existing epoxy processes.

• Low-disruption: Minimal impact on resin viscosity and density, reducing formulation adjustments.

FAQ

What is the minimum order quantity (MOQ)?

Our standard MOQ is 1 kg for sample evaluation. For bulk orders, we recommend starting from 20 kg to enjoy better pricing and stable batch consistency.

Can you provide free samples for testing?

Yes, we can provide small free samples (typically 10–50 g) for initial evaluation. The courier cost is normally covered by the buyer, and it can be deducted from the first bulk order.

How should SWCNT powder be dispersed?

Due to their ultra-high aspect ratio and strong van der Waals forces, SWCNTs are much harder to disperse than conventional carbon black. We recommend using high-shear mixing, ultrasonic dispersion, or three-roll milling, combined with suitable surfactants or dispersants (such as NMP or specific polymers) to prevent agglomeration. To completely bypass the dispersion challenge, we also offer pre-dispersed water-based or NMP oil-based SWCNT conductive slurries for direct use in your production.

What is the lead time for bulk orders?

Samples can be shipped within 3–5 working days. For bulk orders, the lead time is usually 10–20 working days depending on quantity and customization requirements.

Do you support customized specifications?

Yes. We can customize purity, diameter, length, surface functionalization and packaging according to your application. Please contact us with your detailed requirements.
