塗料用添加剤の基礎と不具合現象

摘要

Additives are essential materials to achieve high functionality and high performance coatings. They improve various coating defects and failures of coated films. The present paper shows the incorporation method and mechanism of action of additives through consideration of rheology profile and surface/interfacial tension properties. It is important and useful to know the effect and function of additives in order to understand how they work in coatings. Additives improve the coating profile by providing high functionality and high performance in several fields.%添加剤は，塗料の不具合現象や欠陥現象を防止し, 高機能化や高性能化に寄与するファインな塗料原料である。塗料の流動性や表 面·界面張力に起因する欠陥現象を解説し，それを防止する添加剤の種類や使い方について述べる。添加剤の作用や機能を把握して 添加することが，さまざまな分野におけるコーティング材料の高機能化や高性能化に大きな役割を果たす。
