영문 초록

In order to synthesize high-solid coatings, acrylic resins (HSAs) containing 90% solid content were first synthesized, then the synthesized HSAs were cured with a curing agent, isocyanate, at room temperature to obtain high-solid coatings. In the HSAs synthesis, conversion was in a range of 82∼87%, and viscosities and number-averaged molecular weight (Mn) of the HSAs were in a range of 4380∼8010 cP and 1540∼1660, respectively. From the correlation between Tg value, viscosity and Mn, it was found that, with increasing Tg value, viscosity increases rapidly and molecular weight increases slowly. From the visco-elasity measured by the pendulum method, it was found that the curing time decreased with increasing Tg values. From the tests of physical properties of the coatings’ film, 60〫 specular gloss, impact resistance and heat resistance were proved to be good and pencil hardness, drying time and pot-life were proved to be poor.
