Bubbles Plaguing Your Adhesive? ChemiTech Defoamers Restore Smooth Production

On the production floor, Engineer Wang stared at the churning foam in the adhesive tank, his brow furrowed. This batch of high-transparency specialty adhesive demanded impeccable final appearance; even the tiniest trapped bubble could be grounds for customer rejection. Previous attempts with various methods yielded unsatisfactory results – either incomplete defoaming left microscopic bubbles hidden within the adhesive mass, or the defoamer negatively impacted the adhesive's viscosity stability, making subsequent coating processes difficult to control. Production was stalled, and every minute meant mounting costs.

This scenario is all too common across diverse adhesive applications. Whether it's precision dispensing for electronic component encapsulation or laminating for high-end packaging materials, bubbles act like hidden saboteurs. At best, they cause surface imperfections and reduced gloss; at worst, they critically undermine bond strength and product yield. Traditional physical deaeration methods are time-consuming, labor-intensive, and often unreliable.

The ChemiTech technical team possesses a deep understanding of the complexities within adhesive systems. We recognize the multifaceted origins of bubbles – air entrainment during mixing, gaseous by-products from reactions, or the inherent tendency of the formulation to stabilize foam. Generic defoamers often prove incompatible, leading to issues like haziness, fisheyes, or simply lacking the persistence needed, allowing foam to regenerate during filling, coating, or spraying operations.

To address the specific challenges of adhesives, ChemiTech has developed specialized defoamer series. Their effectiveness lies in carefully selected modified silicones and unique non-silicone polymer systems. These agents rapidly penetrate bubble walls, achieving both efficient 'bubble breaking' and long-lasting 'foam suppression'. Crucially, they exhibit excellent compatibility with a wide range of adhesive bases (such as acrylates, polyurethanes, EVAs, etc.). Incorporation does not cause cloudiness, separation, or abnormal viscosity fluctuations, preserving the adhesive's inherent clarity and transparency.

Equally important is their outstanding persistence. Throughout the entire process chain – from high-speed mixing and pumping to coating or spraying – ChemiTech defoamers continue to perform effectively, suppressing foam reformation. This ensures the adhesive remains uniform and smooth from the production source right through to the end application. As Engineer Wang confirmed: ‘After adding ChemiTech, the foam in the tank visibly dissipated quickly. The adhesive flowed better, coating uniformity improved significantly, and most importantly, the final product was virtually free of bubble defects.’

Choosing ChemiTech's specialized adhesive defoamers is more than selecting an additive; it's an investment in quality assurance and production efficiency. Let us help you eliminate the bubble barrier and unlock the full potential of your adhesive.
