Left uncontrolled, foam can lead to surface defects, reduced gloss, inconsistent film thickness, and slower production. Anti-foam additives (also known as defoamers) are critical tools for resolving this issue and ensuring product quality and efficiency.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\"><strong>What Is Foam and Why Does It Form?<\/strong><\/h3>\r\n\r\n\r\n\r\n<p class=\"\">Foam is formed when air gets trapped in a liquid, stabilized by surfactants and surface-active agents present in the formulation.
