2. Features:The theoretical functionality of RU-907C is 9, with high UV curing activity. The cured coating has excellent solvent resistance, scratch resistance, and wear resistance, high hardness, and good resistance to yellowing and weather. However, its brittleness is relatively high and needs to be compensated by adjusting the formula. It has excellent adhesion properties to various plastic substrates such as PC, ABS, PMMA, PET, etc.
