Using BeNano 90 Zeta to measure the particle size and zeta potential of multicolor UV-sensitive resins
Nanoparticle Size Matters
Multicolor UV-sensitive resins drive innovation in 3D printing, industrial inks, and high-performance coatings. Manufacturers increasingly introduce nano-sized pigments and additives to enhance product performance. When you reduce particle size to the nanoscale, you vastly improve the resin’s glossiness, brightness, and curing speed. Nanoparticles also ensure uniform colour distribution and smoother layer adhesion during the 3D printing process.
The Agglomeration Challenge
However, formulating these advanced resins presents a significant challenge. Nanoparticles possess high surface energy and naturally tend to clump together. Instead of remaining finely dispersed, they often form larger agglomerates. This agglomeration ruins the uniformity of the liquid, destabilises the mixture, and clogs 3D printer nozzles. Formulators must accurately assess both the actual particle size within the liquid matrix and the overall suspension stability to prevent these issues.
Precision Measurement with BeNano 90 Zeta
The BeNano 90 Zeta provides the ultimate solution for characterising these complex UV-sensitive mixtures. This advanced instrument utilises Dynamic Light Scattering (DLS) to capture the precise hydrodynamic diameter of the particles in the resin. It reveals whether your particles truly remain at the nanoscale or if they have clustered into larger aggregates.
Simultaneously, the system measures Zeta Potential via Electrophoretic Light Scattering (ELS)
Zeta potential quantifies the surface charge of the nanoparticles, which directly dictates the electrostatic repulsion between them. A high zeta potential confirms strong repulsive forces, ensuring that your particles repel each other and maintain a stable, long-lasting dispersion.
By integrating the BeNano 90 Zeta into your research and development workflow, you gain critical, real-time insights into your resin formulations. This precise data allows you to optimise your chemical recipes, guarantee product uniformity, and deliver stable, premium-grade multicolor UV resins to the market.
