TERADA TERADITE TRU-0500K2 UV-LED Curable Conformal Coating Resin
TERADITE TRU-0500K2 is a special UV-curable functional resin developed by Terada Co., Ltd. It belongs to the TERADITE Special UV Curable Resin series, which is designed for adhesive and coating applications and supports UV-LED curing. TRU-0500K2 is specifically positioned as a Conformal Coating grade for protective coating of electronic and electrical assemblies. At 25°C, its viscosity is approximately 550 mPa·s, providing good flow and spreading behavior for thin, uniform coating applications. After curing, the material has a hardness of approximately Shore D 58, a Tg of approximately 10°C, and a CTE of approximately 100 ppm/K. It supports UV-LED curing, with a recommended curing energy of 1,500 mJ/cm². The manufacturer’s cross-cut adhesion results are 25/25 on both SUS and PC substrates under the stated test conditions.
