TERADA TERADITE TRU-0251FR High-Tg Flame-Retardant UV Curable Functional Resin
TERADITE TRU-0251FR 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-0251FR is characterized by High Tg / Flame Retardant performance. At 25°C, its viscosity is approximately 1,300 mPa·s, providing good flow and coating behavior. After curing, the material has a Shore D hardness of approximately 85, a Tg of approximately 91°C, and a CTE of approximately 98 ppm/K. The catalog lists TRU-0251FR as a flame-retardant UV-curable grade with a recommended curing condition of 1,500 mJ/cm² using a UV metal-halide lamp. LED curing is not supported for this grade.
