NC-7000 series is an epoxy resin with a naphthalene structure and is characterized by high heat resistance, elastic modulus, and low water absorption.
Since naphthalene is a rigid structure and has high fat solubility, the performance after water absorption are less likely to deteriorate, and high heat resistance and elastic modulus can be maintained. In addition, the cresol is inserted between the naphthalene structures so that it does not become too hard and maintains well-balanced properties.
