It has the characteristics of easy dispersion, rapid defoaming, high stability and strong adaptability.
XDD-806/804/802 powder defoamer is capable of defoaming microbubbles generated during construction or
production of building materials, and provides excellent durability and shear stability and increased strength.
Nature and application:
XDD-806/804/802 powder defoamer is recommended to use dry mix of concrete and admixture before adding
water. The addition of 806/804/802 powder defoamer will reduce the bubble of the solution, especially almost no The water-based paddle or mud block of the air has good defoaming effect. In some powder systems, such as: XDD-806/804/802 powder defoamers have a flowing nature. Especially suitable for the industry of parquet flooring. This product is very easy to use. All powder systems, such as powder coatings, powders, plaster walls and concrete, work well with this product.
XDD-806/804/802 powder defoamer is mainly used in: 1. caulking agent; 2. inner and outer wall putty; 3. bonding
mortar; 4. decorative mortar; 5. waterproof mortar; 6. gypsum prefabricated board; .Gypsum plaster; 8. Cement and gypsum-based self-flowing equal mortar.
Features:
1. It has good dispersibility in the system, good antifoaming effect and rapid defoaming.
2. Low dosage and high efficiency.
3. Effectively control the foam generation in the mortar system to make the concrete members more dense and bright.
4. This product has strong adaptability to other admixtures.
Suggested addition amount:
Generally, the amount of the total amount of the material added is XDD-806/804/802 powder defoamer is 0.1 to 1.0%.
XDD-806/804/802 powder defoamer has excellent workingability and transportation because of its very good fluidity. In addition, the XDD-806/804/802 powder defoamer is compatible with all powder coatings. For best results, please test in advance.

Antifoaming agents refer to substances that can reduce the surface tension of water, solutions, suspensions, etc., prevent foam formation, or reduce or eliminate the original foam. During paper making, foam will accumulate in the wet paper system due to unreasonable sizing, poorly washed pulp, use of basic filler in acidic system, and addition of various additives, resulting in formation of foam spots on the paper that is copied, such as transcurtain and so on. Depending on the situation, various types of antifoam agents can be added in the paper manufacturing procedure. Antifoam agents in early use were hydrocarbon oils such as coal oil, paraffin oil, sulfonated oils, sodium oleate, octanol, and others. Among the effective components of the more recently used antifoam agents are silicones, polyether type surfactants, aliphatic amide type surfactants, etc. Antifoam agents can be further divided into oil-based and water-based antifoam agents, and their effective active components are generally the same, the advantage of water-based antifoam agents is that it has extremely little effect on various other additives, does not produce accumulation in the circulation, avoids the occurrence of resin barriers, and thus is the direction of development.
