| Abstract: | The paper presented the synthesis of an hydroxy polyester resins used for powder coatings.The glass transition temperature(Tg)of the polyester resin was determined by use of differential thermal analysis(DTA),the physicochemical properties,such as acid value,hydroxyl value and molten viscosity were tested.The textured powders,such as wrinkle and tortoise patterns were made from the polyester resin,and the paper discussed the impact of hydroxyl value and monomers on the texturing effect of wrinkle powder from hydroxy polyester and the influence of different powder formulations on the texturing effect of tortoise pattern powder was discussed too.The weathering performance of polyester resin-based powder coatings was tested.The results showed that the prepared polyester provided lower acid value,higher glass transition temperature,resulting in an excellent texturing effect of wrinkle and tortoise pattern,while flat coatings could provide excellent weather resistance. |
