Description
SWCNT Pre-Dispersion for Thermosetting Systems (CTISO-01)
CTISO-01 disperses single-walled carbon nanotubes uniformly and efficiently in solvent-free epoxy and other thermosetting systems, including polyurethane, rapidly forming a stable, dense conductive network. At ultra-low dosage it imparts efficient, durable antistatic properties with minimal impact on the base resin’s mechanical properties and chemical resistance, avoiding the performance degradation and substrate damage associated with conventional conductive fillers. It is intended for resin formulators and compounders buying at drum-and-up volumes for coatings, flooring, and composite production.
Core Features
- Excellent adaptability: no significant modification of formulations or processing equipment.
- Low addition, high cost-effectiveness: extremely low dosage that does not significantly raise system viscosity.
- Environmental protection with low precipitation: formulated to minimize free carbon particle release throughout service life.
- Long-lasting antistatic effect: permanently reduces surface and volume resistivity of epoxy, polyurethane, and similar resins.
Base SWCNT feedstock: 1-2 nm outer diameter, ≥98% purity by TGA (see the SWCNT Powders page for full grade specification).
Application Example (D.E.R. 351 Pure Resin, No Other Additives)
| CTISO-01 Addition (%) | Net SWCNT (%) | Sheet Resistance (Ω) |
|---|---|---|
| 0.1-0.5 | 0.01-0.05 | 10&sup5;-10&sup6; |
| 0.5-1.0 | 0.05-0.1 | 10&sup4;-10&sup5; |
| 1.0-2.0 | 0.1-0.2 | 10³-10&sup4; |
Addition amounts calculated on total resin weight including curing agent; dispersed with a 50 mm dispersion disc at 3800 rpm for 20 minutes.
Recommended Evaluation
- Initial screen at 0.05%, 0.10%, and 0.15% net SWCNT of total resin weight to map the effect on each performance indicator.
- Optimal dosage: confirm with repeated multi-batch trials, since dosage and efficacy depend on formulation, raw-material type, and temperature.
Applications
- Antistatic flooring
- Electronic packaging materials
- Aviation and aerospace precision components
- Explosion-proof equipment
- High-performance composite structural parts
- Conductive gelcoats and other industrial applications with stringent antistatic requirements
