The printing industry continually seeks advancements to improve efficiency and final product quality. For UV inks, achieving a smooth, consistent print without visual defects like pinholes or craters is essential. Microfoam generated during the ink manufacturing and application process can significantly hinder these goals. This is where high-performance defoamers, particularly modified silicone-based types, offer a critical advantage.

UV inks are designed to cure rapidly when exposed to ultraviolet light, offering benefits such as fast drying times and durability. However, the formulation process, which often involves high-speed mixing and dispersion of pigments and photoinitiators, can introduce air, leading to foam. This foam, if not controlled, can result in uneven ink transfer, reduced adhesion, and unsightly surface imperfections on the printed substrate.

Modified silicone defoamers are engineered to combat these issues effectively. Their unique chemical structure allows them to spread rapidly across the air-liquid interface, reducing surface tension and causing foam bubbles to collapse. Unlike some organic defoamers, silicone-based products often exhibit excellent thermal stability and shear stability, making them suitable for demanding printing processes. Our modified silicone defoamer, for example, is specifically designed for high viscosity and solvent-free systems, common in advanced UV ink formulations.

When incorporating a defoamer into your UV ink formulation, it's vital to consider its compatibility and dosage. Typically, a low addition percentage, often between 0.01% and 1.00%, is sufficient to achieve significant foam reduction. It’s also advisable to perform compatibility tests to ensure the defoamer doesn't negatively affect the ink's rheology, curing speed, or adhesion properties.
