大研化学工業 List of Products and Services

Our company provides nano-dispersion technology using ultra-fine zirconia beads. By refining the mixture and achieving high-quality dispersion, it is possible to uniformly impart functionality. We have developed a product without dispersants (additives) to minimize the impact on resins while maximizing the filler function of the dispersion liquid. This ensures the transparency and mechanical properties of the resin after film formation. The ND series of hollow silica dispersion liquids has characteristics that improve compatibility with customer resins and can be adjusted to meet hydrophobic and hydrophilic requirements. 【Product Lineup】 ◎ ZrO2 dispersion liquid: DLZ-001-30NDOFS, DLZ-001-30A6END ◎ BTO dispersion liquid: DLB-001-20TO40NAEND ◎ TiO2 dispersion liquid: DLT-001R-25ND ◎ Silica dispersion liquid: ・Hollow → DLSB-001-30SNA-16ND/-17ND ・Spherical → DLS-001-3050SKND ◎ ATO dispersion liquid: DLAT-002-30ND *Our company also handles contract production and sales of nano-dispersion liquids.
