In the production, transport and high-speed printing of water-based inks, the generation of foam is a common and troublesome problem. Excessive foam leads to an unstable ink tank level and affects pumping efficiency, and moreover forms defects such as white spots, pinholes or fisheyes on the printed surface, seriously reducing the product qualification rate and production efficiency. Traditional defoaming methods often have only a short-lived effect, or have poor compatibility with the system, and may trigger new problems such as craters and reduced gloss.
To address these market pain points, Chemi Tech has developed, on the strength of its professional surface chemistry technology, a series of high-efficiency antifoams for water-based inks. Our solution emphasizes not only fast foam breaking but also lasting foam suppression, ensuring stability throughout the entire process. The products are carefully designed to have good compatibility with various water-based resin systems, and while defoaming efficiently, can effectively avoid negative effects on ink transparency, tinting strength and the final print result.
Our specific solution steps are clear and definite: first, our technical team conducts an in-depth analysis of the customer's specific ink system, production process and foaming environment to precisely locate the root cause of the foam. Second, we screen out the best-matching antifoam model from our product library, which may be a composite product based on polyether-modified silicone or special mineral oil. Then, we provide detailed dosage recommendations (usually between 0.1% and 0.5%) and guidance on the dosing point (for example, the grinding stage or the let-down stage). Finally, we support customers in conducting on-site or laboratory application tests to verify the defoaming effect and system compatibility, ensuring nothing goes wrong.
A typical case is a printing enterprise that encountered severe foam in its new high-speed flexographic printing ink, causing unstable surface quality of the printed matter. After adopting the specific antifoam model recommended by Chemi Tech, the foam was brought under immediate and lasting control under stirring and high-speed printing conditions. The ink's transferability and leveling were improved, the surface uniformity and color saturation of the printed matter rose significantly, and the operating efficiency of the production line increased substantially thanks to reduced downtime and cleaning frequency. The customer spoke highly of the stability of the final effect and the cost-effectiveness of the product.
Choosing Chemi Tech means choosing a reliable and efficient foam control solution. We are committed to helping every customer optimize the performance of their water-based inks, overcome foam obstacles, and achieve smoother production and more outstanding print quality.
