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.
