Basic Information

EPOSTAR™ are heat-cured, spherical fine particles with melamine and benzoguanamine resins as raw materials.
We offer nine types of standard item numbers, with three types of resin structures.

Features and Properties

1. Excellent heat resistance and solvent resistance
2. Particle size adjustable from 0.1 – 9μm
3. High refractive index (n = 1.66) derived from a resin backbone densely containing nitrogen atoms.
4. Exhibits a tendency to acquire a positive charge
