These are organic resin microparticles with a particle diameter in the nanoscale and a hollow interior. They are provided in a solvent dispersion to achieve primary dispersion of the nanoscale particles. 〇 Features (1) The particle diameter is nanoscale, and the particle size distribution is uniform, allowing for the creation of a highly transparent low refractive index film when added to materials. (2) Being polymer microparticles, they have good compatibility with resin materials and organic solvents, resulting in excellent dispersibility. (3) Compared to inorganic hollow particles, the organic NH series has a lighter weight per particle, leading to a higher number of particles when added in the same weight, resulting in enhanced properties. (4) They have high affinity with the coating film, making it less likely for cracks to occur during film bending or punching processes. (5) The hollow structure allows for expected properties such as weight reduction, thermal insulation, and low dielectric constant in addition to lowering the refractive index. 〇 Comparison of reflections due to low-reflection films By adding to the coating film, the refractive index decreases, reducing light reflection. 〇 Comparison of coating film strength during film bending Since TP-NH is a resin composition, it has high compliance with organic binders, resulting in a coating film with excellent bend resistance.
