Co-crosslinking Agent (TAC)

TAC is a light yellow to colorless liquid or crystal at room temperature with a melting point of 25-27℃, a density of 1.1133 g/ml (at 30℃), a viscosity of 1.26×10-2 Pa•s (30℃) and a refractive index of 1.5049 (25℃). TAC is hardly soluble in water and soluble in ethanol, acetone, heptane, petroleum ether, solvent oil, soybean extract oil, halogenated hydrocarbon, and the like. TAC is stable at room temperature and can be stored stably for a long time.
