Properties and Applications
The recommended use of powder defoamer is to mix it dry with concrete and admixtures before adding water. This reduces bubbles in the solution, leading to a nearly air-free aqueous slurry or paste, achieving an effective defoaming result.
Powder defoamer has flowing properties, making it highly suitable for the wood flooring industry. It is very easy to use in powder systems like powder coatings, filler adhesives, plaster walls, and concrete, with excellent compatibility.
