One-component UV-curable urethane acrylate resin. Suitable for substrate coating. Excellent workability with low viscosity of 550 mPa·s and quick curing for mass production.
The 『TRU-0500K2』 is a one-component UV-curable urethane acrylate resin developed for moisture-proof coating applications on electronic circuit boards. Its one-component design, which requires no mixing, makes it easy to handle, and it allows for rapid curing through UV irradiation (1,500mJ/cm²), making it suitable for energy-efficient and effective mass production processes. This product features a low viscosity design of 550mPa·s (25°C), providing excellent workability and making it easy to coat complex part shapes and narrow areas. The cured material has a Shore D hardness of 58, balancing flexibility and strength. Additionally, it boasts excellent insulation properties with a dielectric breakdown strength of 30kV/mm and a volume resistivity of 2×10^15Ω·cm, supporting the long-term reliability of electronic devices. The appearance is transparent, allowing for use without compromising the aesthetics of circuit boards and electronic components. 【Features】 ■ One-component UV-curable urethane acrylate resin ■ Low viscosity (550mPa·s) for good workability ■ High moisture resistance (water absorption rate of 0.3%), ensuring long-term reliability *For more details, a product specification sheet is available for download as a PDF below, or please contact us. *Samples are also available, so please reach out if needed.
