Industrial glue defoamer is an additive used to reduce or eliminate bubble formation in glue during production and application. The presence of bubbles will not only affect the bonding performance of the glue, but may also cause problems with the appearance and strength of the final product. Therefore, the use of defoamers is an important step to ensure the quality of industrial glue.

The role of defoamers

1. Reduce surface tension: Defoamers can effectively reduce the surface tension of liquids, thus promoting bubble rupture.

2. Accelerate foam loss: By changing the foam structure in the liquid, defoamers can accelerate foam loss time.

3. Improve bonding performance: After removing bubbles, the bonding effect of glue will be better, enhancing the performance of the final product.

Common types

1. Silicone-based defoamer: Based on silicone oil, it has good high temperature resistance and chemical stability, and is suitable for a variety of glues.

2. Polyether defoamers: Usually used in water-based glues, can quickly defoam, economical and practical.

3. Organic acid salts: Suitable for certain types of industrial glues.

Precautions for use

1. Compatibility: The selection of a suitable defoamer needs to consider its compatibility with the glue.

2. Addition amount: Excessive use of defoamers may affect other properties of the glue, so it should be adjusted according to specific needs.

3. Stirring method: The addition of defoamers requires reasonable stirring to ensure uniform dispersion.
