How to Solve Glue Foaming Issues? Chemi Tech Defoamer Provides Effective Solution

Foaming frequently occurs during glue production and application, which not only affects product appearance but also reduces adhesive strength and sealing performance. Foam issues can lead to decreased production efficiency, lower product qualification rates, and even material waste. Addressing this common industry challenge, Chemi Tech has developed a series of specialized defoamers through years of technical accumulation, providing customized solutions for various adhesive systems.

The main causes of glue foaming include air entrainment during mixing, gas generation from chemical reactions, and excessive surfactant content. Targeting these pain points, Chemi Tech defoamers utilize specially modified polysiloxanes and high-efficiency active components to rapidly break bubble surface tension, achieving instant defoaming and persistent foam suppression.

The specific solution involves three steps: First, select the appropriate defoamer type based on the adhesive system (such as water-based glue, epoxy resin, UV glue, etc.). Second, conduct tests with 0.1%-0.8% dosage to determine the optimal ratio. Finally, adopt phased addition during production to ensure even dispersion of the defoamer.

An adhesive manufacturer encountered severe foaming issues when producing water-based acrylic glue, with product qualification rates barely reaching 75%. By implementing Chemi Tech KM-108 defoamer at 0.3% dosage and high-speed dispersion, bubbles were completely eliminated, increasing product qualification to 98.5% while significantly improving glue transparency.

Chemi Tech defoamers feature low dosage requirements, excellent compatibility, and no impact on original adhesive properties.
