During the production, stirring, filling, and application of adhesives, the generation of bubbles is a common and troublesome problem. These tiny bubbles not only affect the appearance of the product, but more directly lead to reduced adhesive layer strength, incomplete bonding surfaces, and coating defects; in severe cases, they even trigger customer complaints and product scrapping. How to efficiently and durably eliminate these bubbles is a common challenge faced by many manufacturers.
The common pain point in the market is that many defoamers either have a slow defoaming speed or a short foam-suppression time, and generate bubbles again after the system is stored or subjected to application shear. In addition, the compatibility problem between the defoamer and the system may cause the adhesive to become turbid, produce surface shrinkage cavities, or affect the final bonding performance. Choosing a defoamer with balanced performance and strong adaptability is crucial.
In response to these core needs, Chemi Tech has launched a defoamer series designed specifically for adhesive systems. Our solution is based on in-depth research into polymer systems and creates value for customers through the following steps: The first step is precise analysis. Our technical team will learn in detail about your adhesive base material, production process, and the stages where bubbles are generated. The second step is product selection and testing. From our product library of silicone, non-silicone, and mineral oil defoamers, we screen out candidate products with good compatibility with your system and high defoaming efficiency. The third step is formulation optimization and verification. Under laboratory conditions simulating actual production, we carry out comprehensive tests on defoaming speed, foam-suppression durability, and final product performance, to ensure that the addition of the defoamer does not affect the core physical properties of the adhesive. The fourth step is production guidance and follow-up. We provide the optimal dosage and addition process recommendations, and follow up on the batch production effect.
We once helped a customer focusing on electronic packaging adhesives solve its pain point. After high-speed stirring and vacuum defoaming, the customer's product still continuously generated micro-bubbles during filling, affecting dispensing precision and packaging reliability. Through Chemi Tech technical analysis, we recommended a modified silicone defoamer with excellent foam-suppression performance and optimized the timing of addition. After application, the amount of bubbles generated during the filling process of the customer's adhesive was significantly reduced by more than 90%, the product appearance was clear and uniform, and the dispensing smoothness was improved; finally the air-tightness test pass rate of the packaged product was greatly increased, earning positive feedback from the customer.
Choosing Chemi Tech means choosing a commitment to quality. Our defoamers are not only committed to rapid foam breaking, but also focus on long-lasting foam suppression and system stability, helping your adhesive products stand out in the market competition with reliable appearance and performance.
