Putty powder is a kind of building decoration material, the main component is talcum powder and glue, is the key component of putty, mainly plays the role of bond. Putty commonly used binder is cement and organic polymer, organic polymer and latex powder. Putty powder foaming, because putty powder contains binder, surfactant and other additives, and these additives will produce a large number of bubbles in the operation.Putty powder foaming is easy to cause paint, latex paint in the construction of quality problems.Add in coating water defoaming agent can be exempted from the problem specifically speaking mainly have the following points:1. Foam will affect the production schedule and product output.2. Excessive bubbles are easy to lose raw materials and increase production costs.3, foam will bring different degrees of defects to the finished film.4. Excessive bubbles will hinder the normal production and construction of coating.Defoaming agent is suitable for the area under the condition of strong acid alkali soaking, putty powder antifoaming agent under the condition of this can maintain good physical condition, demulsification, floating oil, foam rather than normal temperature strong broken bubble foam suppression effect, fast defoaming, inhibit for a long time, and no poison, taste, won't cause pollution to the environment, use new earth defoaming less dosage, low use cost. Can be directly added into the foaming system, before use to stir evenly, the recommended dosage is 0.05%~0.3%, the actual dosage can be determined according to the results of use. Because the foaming property of each system is different, there are many reasons for foaming.
