In precision optical coatings, the dispersant’s clarity dictates end-product light transmission and surface uniformity. Chemi Tech’s KMK-100 series utilizes unique molecular design to disperse nano-metal oxides (e.g., TiO₂, ZrO₂) while maintaining ≥99.5% transmittance. Core innovations include:
Sub-10nm Particle Control: Anchoring groups and steric hindrance synergistically suppress agglomeration below visible light scattering thresholds.
Surface Energy Matching: Molecular chains tailor compatibility with resin substrates, eliminating phase-separation micro-defects.
A leading screen manufacturer faced transmittance loss (initial 92%) due to ZrO₂ nanoparticle (30nm) agglomeration. After adopting KMK-100:
Coating transmittance reached 99.8%, haze reduced from 1.5% to 0.2%
Pencil hardness increased by 1H grade (to 8H)
Production yield rose 15% as dispersion stability extended slurry shelf life to 3 months
This technology also enables AR glasses to achieve full-spectrum transmittance consistency (<0.3% fluctuation) in 0.1mm coatings, breaking thickness-clarity trade-offs.
