THERMAL-FLOWABILITY REGULATOR FOR POWDER COATING COMPOSITION, PROCESS FOR PRODUCING THE SAME, AND POWDER COATING COMPOSITION

摘要

Disclosed are a thermal fluidity modifier for a powder coating material, which contains a polymer containing t-butyl (meth)acrylate units and having a glass transition temperature (Tg) of 20 to 120°C as calculated by the following equation (1): 1 / Tg = ˆ‘ w i / Tg i
wherein w i represents a mass fraction of monomer i which constitutes the polymer and Tg i represents a glass transition temperature of a homopolymer of the monomer i; and a powder coating material containing the thermal fluidity modifier.
