Functionalized Core-Shell Microparticles

Advanced impact modifiers for thermoplastics and epoxy-based coatings.
Enhance toughness, crack resistance, and mechanical strength in high-performance materials.

High-Efficiency Tougheners for Thermosets, Coatings, and Engineering Plastics

NAGASE’s functionalized core-shell microparticles are engineered as high-performance impact modifiers and tougheners for a wide range of materials. Designed for use in thermoplastics, epoxies, unsaturated polyesters (UPEs), powder coatings, and UV-curable formulations, they significantly improve mechanical strength and crack resistance.

The particles feature a functionalized shell for strong interaction with polymer matrices and a soft core that absorbs impact energy. This dual-structure design ensures optimal dispersion, long-term stability, and enhanced durability of the end-product.

NAGASE supplies functionalized core-shell microparticles globally for industrial coatings, adhesives, electronics, and composite materials – with formulation support and custom particle solutions.

Applications
