CYCLOALKANE DICARBOXAMIDE COMPOUNDS, THEIR PREPARATION AND APPLICATION

摘要

PURPOSE: A cycloalkane dicarboxamide compound is provided to improve mechanical strength and heat resistance when used as a hardener of polyester powder resin. CONSTITUTION: A cycloalkane dicarboxamide compound is represented by formula 1. In formula 1, R1~R4 are independently linear or branched C1-C7 alkyl groups of which one or more hydroxyl groups are substituted; R9 and R10 are independently hydrogen, hydroxyl group, or hydroxyl-substituted or non-substituted C1-C7 alkyl groups; and m and n are independently integers between 1 and 3.
