TERADA TERADITE TRU-0250K High-Thixotropy High-Heat-Resistance UV Curable Functional Resin
TERADITE TRU-0250K is a UV-curable functional resin developed by Terada Co., Ltd. It belongs to the TERADITE UV Curable Resin series, which is designed for adhesive and coating applications and emphasizes rapid UV curing, good workability, heat resistance and moisture resistance. TRU-0250K is characterized by High T.I (T.I 3.7). Its viscosity at 25°C is approximately 158,000 mPa·s, providing strong shape retention and making it suitable for dispensing, localized coating and applications where sagging or flow must be minimized. After curing, the material has a Shore D hardness of approximately 86, a Tg of approximately 125°C, and a CTE of approximately 32 ppm/K. The recommended curing condition is 1,500 mJ/cm² using a UV metal-halide lamp. The catalog does not indicate LED-curing compatibility for this grade.
