Water-based glue plays an important role in many industrial production and daily application scenarios. From paper packaging, textile printing and dyeing to architectural decoration, it is favored by its environmental protection and easy use. However, water-based glue often has foam problems during use. These foams not only affect the appearance and quality of the product, but also may reduce production efficiency. The emergence of water-based glue defoamer effectively resolves this problem.

There are many factors that make water-based glue prone to foaming. First of all, the surfactant in its formula plays a key role. In order to make water-based glue have good wettability, dispersibility and stability, a certain amount of surfactant is usually added. However, these surfactants reduce the surface tension of the glue while making it easier for air to enter the glue system and form foam.

The water-based glue defoamer can play a role thanks to its unique working principle. Generally speaking, the defoamer has a low surface tension. When it is added to the water-based glue system, it will quickly disperse on the surface of the glue. Because its surface tension is lower than that of glue, the defoamer can penetrate into the liquid film of the foam and destroy the elasticity and stability of the foam.

When choosing a water-based glue defoamer, multiple factors need to be considered comprehensively. First of all, it should be selected according to the specific composition and use environment of the water-based glue. For example, if the water-based glue is used for bonding in a high temperature environment, then a high-temperature resistant defoamer needs to be selected to ensure that good defoaming performance can be maintained under high temperature conditions.

Water-based glue defoamers play an irreplaceable role in solving the problem of water-based glue foam. With the continuous expansion of the application field of water-based glue and the increasing requirements for product quality, water-based glue defoamers will continue to develop and innovate, providing better quality and efficient defoaming solutions for the production of various industries.
