In improving the performance of coating agents, the question of whether to increase or decrease surface tension is surprisingly an area that has led to many misunderstandings. In this series, we will explain in detail five performance aspects where surface tension has a particularly significant impact, one by one. Leveling, wetting, beading and cratering, hydrophilicity and hydrophobicity, and recoatability. In the final installment, we will organize all these topics from a comprehensive perspective to deepen your overall understanding. *For detailed content of the article, please refer to the PDF.
