High quality defoamers should be able to quickly eliminate bubbles in cement mortar in a short period of time. In addition to defoaming, defoamers should also have long-lasting anti foaming ability to prevent the generation of new bubbles. Defoamers should be compatible with other components in cement mortar and not affect their overall

performance. And in harsh environments such as high temperature and high humidity, defoamers should maintain stable performance.

In the selection of defoamers, it is necessary to clarify the requirements and choose the appropriate type of defoamer according to the specific needs of the project. Choose defoamers produced by manufacturers with good brand reputation and word-of-mouth. Compare the technical performance indicators of different products and choose

the product with superior performance. Taking into account factors such as product price, usage, and construction efficiency, choose products with high cost-effectiveness.
