        ①In the same formulation, gloss may have deviation due to the adoption of different
        polyesters . Generally, polyesters with slow reaction speed have lower gloss.
        ②Less amount of TGIC could be consumed by T-302B. In order to obtain better mechanical
        properties, normally excess TGIC and T-302B ratio of about 10/1.
