T-7128F is a high-performance UV-curable resin specifically developed for challenging inorganic substrates such as glass, ceramics, and metals. With its low acid value, high double-bond conversion rate, extremely low shrinkage, and outstanding water resistance, it delivers exceptional performance in metal printing inks, UV adhesives, and vacuum coating primer applications.
Particularly in metal printing inks, T-7128F enables rapid curing under low-energy LED exposure while maintaining strong and stable adhesion, meeting the demands of high-efficiency and high-reliability industrial production.
Key Features
| Feature | Description |
|---|---|
| LED Low-Energy Rapid Curing | Compatible with long-wavelength LED light sources (e.g., 365 nm / 395 nm) for fast surface and through-curing, improving production efficiency |
| Excellent Adhesion to Metals | Outstanding adhesion to tinplate, aluminum, stainless steel, and other metal substrates; performs well without additional adhesion promoters |
| Low Shrinkage | Minimal volumetric shrinkage reduces internal stress, ensuring print precision and adhesion stability |
| High Double-Bond Conversion | Thorough curing enhances coating density, ensuring reliable performance in post-processing (e.g., vacuum metallization, stamping) |
| Boiling Water & Retort Resistance | Maintains excellent adhesion and flexibility even after boiling water exposure, suitable for retort-grade packaging applications |
| Low Acid Value, Low Odor | Non-corrosive to metal substrates and user-friendly in production environments |
