    Epoxy adhesives are widely used in many fields due to their excellent bonding properties, good chemical stability and mechanical properties. However, in the preparation and use of epoxy adhesives, foam problems often occur, which has an adverse effect on their performance. The rational application of epoxy adhesive defoamer becomes the key to solving this problem.

    In the preparation of epoxy adhesives, due to the high viscosity of epoxy resin, air is easily involved in the stirring process to form foam. The presence of foam in epoxy adhesives will reduce the effective contact area between the adhesive and the bonded material. During the bonding process, the space occupied by the foam will prevent the adhesive from fully filling the bonding interface.

    Characteristics of epoxy adhesive defoamer:

    1. Compatibility with epoxy adhesives

    Epoxy adhesive defoamer has good compatibility with epoxy adhesives. It will not react chemically with the epoxy adhesive ingredients, and will not affect the curing reaction process and performance of the adhesive after curing.

    2. Effective defoaming performance

    It can quickly and effectively eliminate the foam in the epoxy adhesive. Whether in the early stage of adhesive preparation or in the static process after mixing, it can quickly reduce the amount of foam and improve the quality of the adhesive.

    3. Durability

    During the storage and use of epoxy adhesives, the defoamer can continue to work. It will not fail quickly due to long-term storage of the adhesive, ensuring that the epoxy adhesive will not have foam problems.

    Epoxy adhesive defoamer plays an indispensable role in the preparation and use of epoxy adhesives. Due to its good compatibility with epoxy adhesives, effective defoaming performance and durability, it helps to improve bonding performance, optimize physical properties and improve product quality and reliability.
