Accelerating New Product Development with CNT Dispersion Liquid [Conductivity with Small Additions]
Achieving strong conductivity, EMI shielding, and thin-film heating with a small amount of CNT high-dispersion liquid. Proposing process-compatible solutions to accelerate the transition from prototyping to mass production.
The CNT conductive dispersion liquid, pursued for high dispersion, achieves conductivity, static charge suppression, and heat generation with a small amount of addition, from thin films to thick films. It enhances implementability with viscosity design that accommodates a wide range of processes such as screen printing, bar coating, spraying, and impregnation, along with particle size management to reduce clogging. It can be applied to various uses such as vehicle-mounted sensor gripping parts, transparent conductive and anti-fog coatings, local EMI shielding around ECUs, interlayer conductivity of CFRP, and thin film heaters. Evaluation samples (100g/500g/1kg) are provided in a short delivery time, and we also support custom requests for solvents, viscosity, and formulations, as well as consultations on safety regulations (SDS, RoHS/REACH). Features: - High dispersion and high concentration (approximately 1–5 wt%) enable conductivity with a small amount of addition. - Functionally variable with low percolation (from static charge prevention to conductivity). - Suitable for printing/coating/impregnation with a viscosity range of 50–800 mPa·s. - Reduced clogging and improved printability with D90 < 500 nm management. - Storage stability (approximately 3–6 months) with a focus on lot reproducibility. - Can accommodate transparent conductive applications with a transmittance range of 80–92%. - Designed for SE (10 MHz–3 GHz) countermeasures, adjustable with film thickness and volume resistivity. *For more details, please refer to the related links or feel free to contact us.*
