Spargerea barierei de vindecare! YS-DYE: O soluție revoluționară pentru întărire UV în înaltă-Sisteme Chroma

In high-end fields such as TFT-LCD manufacturing and electronic inks, UV curing processes for pigmented systems present significant challenges. Traditional photoinitiators struggle to maintain efficient initiation capabilities at high pigment concentrations, leading to low curing efficiency and film defects.

Core Technological Breakthrough: Five Key Advantages of YS-DYE

1. Ultra-Fotosensibilitate ridicată la 365nm

YS-DYE este optimizat special pentru I-line (365nm) lungime de undă, realizarea industriei-conducând la eficiența cuantică fotochimică. Experimental data shows that under the same light intensity, its initiation speed is over 40% faster than conventional oxime ester photoinitiators, făcându-l deosebit de potrivit pentru înaltă-speed continuous production lines.

2. Extreme Pigment Tolerance

It offers breakthrough tolerance for carbon black pigment concentrations up to 35% (SGS certified), providing reliable assurance for Black Matrix (BM) production. Chiar și în sistemele cunivel ridicat concentrations of pigments like phthalocyanine blue or benzidine yellow, it maintains over 90% curing efficiency.

3. Ultra-Thin Film Curing Capability

Its ability to cure ultra-thin layers (1-30μm) meets the thinning demands of modern electronic devices. In 10μm film thickness tests, it achieves complete curing with a single exposure, avoiding the film stress issues caused by multi-stage curing in traditional processes.

4. Excellent Solubility

Its specially designed molecular structure ensures outstanding compatibility in systems like epoxy acrylates and urethane acrylates. Even in high-viscosity systems (>5000 cP), it maintains uniform dispersion, preventing uneven curing caused by photoinitiator aggregation.

5. Intelligent Synergy Adaptability

It supports synergistic use with other photoinitiators like 369, ITX, 819, or TPO. Pentru grosimi de peliculă care depășesc 30μm, o formulare folosind YS-DYE (0,5-1.0%) combined with TPO (1.5-2.0%) achieves a perfect balance between deep curing and surface curing.

 Performanță în scenarii de aplicație

TFT-LCD Color Filters

În testele pe linia de producție G6, YS-DYE a îmbunătățit viteza de întărire la 3,5 m/min (compared to only 2.0 m/min with traditional initiators) in a colored resin system containing 25% titanium dioxide. Abaterea coordonatei culorii ΔE was <0.8, far exceeding the industry standard of ≤1.5.

Electronic Inks

When used in LDI solder mask inks, a synergistic system of YS-DYE/TPO (1:2 ratio) achieved complete curing with a single exposure at 35μm thickness, significantly reducing energy consumption costs. After 1000 hours of testing at 85°C/85% RH, rata de retenție a aderenței filmului a depășit 95%.

Inkjet Printing Applications

In UV inks containing 15% dyes, YS-DYE reduced droplet curing time to 0.8 seconds (traditional products require 1.5 seconds) withnonozzle clogging, making it especially suitable for high-precision industrial printing.
