After using caprolactone and lauric acid to modify hyperbranched polyester, the film properties in gloss, impact resistance, adhesion and flexibility is very excellent. Caprolactone and lauric acid-modifiedhyperbranched polyester has the best performance, lowest viscosity of 7500 mPa • s, the coating is dry in 40 minutes, and the hardness is F. Seperately using caprolactone or lauric acid modifiedHBP-1 and HBP-2, the corresponding data are 7 × 105 mPa • s, 20 minutes, HB, and 17500mPa • of s, 90 minutes and 2B. In addition, coating with lauric acid and benzoic acid-modified hyperbranched polyester in adhesion, hardness and is greatly improved, and increasing the amount of benzoic acid can improve the pendulum hardness.
