Adhesive Foaming Problems? Chemi Tech Defoamers Offer Efficient and Stable Solutions

The generation of foam is a common and troublesome issue during the production, mixing, filling, and application of adhesives. These tiny bubbles not only affect the product's appearance but also directly lead to reduced bond strength, incomplete bonding surfaces, and coating defects, potentially causing customer complaints and product scrap in severe cases. How to eliminate these bubbles efficiently and persistently is a shared challenge for many manufacturers.

Common market pain points include that many defoamers are either slow in defoaming speed or short in foam suppression time, leading to re-foaming after system storage or during application shear. Moreover, compatibility issues between defoamers and the adhesive system may cause haze, surface craters, or impact final bonding performance. Selecting a well-balanced, highly compatible defoamer is crucial.

Addressing these core needs, Chemi Tech launches a series of defoamers specifically designed for adhesive systems. Our solution is based on in-depth research of polymer systems, creating value for customers through the following steps: Step 1, Precise Analysis. Our technical team will gain a detailed understanding of your adhesive base, production process, and foam generation points. Step 2, Product Selection and Testing. From our product library of silicone, non-silicone, and mineral oil-based defoamers, we screen candidate products with good compatibility and high defoaming efficiency for your system. Step 3, Formulation Optimization and Validation. We simulate actual production conditions in the lab, conducting comprehensive tests on defoaming speed, persistent foam suppression, and final product performance to ensure the defoamer does not affect the core properties of the adhesive. Step 4, Production Guidance and Follow-up. We provide recommendations for optimal dosage and addition process, and follow up on batch production results.

We once assisted a client specializing in electronic potting compounds to solve their pain point. The client experienced persistent micro-foaming during dispensing even after high-speed mixing and vacuum degassing, affecting dispensing accuracy and encapsulation reliability. After Chemi Tech's technical analysis, we recommended a modified silicone defoamer with excellent foam suppression properties and optimized the addition timing. After application, the foam generation during the client's adhesive filling process was significantly reduced by over 90%. The product appearance became clear and uniform, dispensing fluency improved, and the final pass rate for airtightness testing of the encapsulated products increased substantially, earning positive feedback from the client.

Choosing Chemi Tech means choosing a commitment to quality. Our defoamers not only focus on rapid bubble breaking but also emphasize long-lasting foam suppression and system stability, helping your adhesive products stand out in the market with reliable appearance and performance.
