The application of coatings is closely related to our daily life, mainly used in automobiles, ships, decoration, and other fields. However, the foam problem during use is also very troublesome. The following 1,3,5,7-Tetramethylcyclotetrasiloxane manufacturer will introduce the addition method of coating defoamer:
1. Add before foaming: This method can suppress foam generation by adding defoamer to the system that may generate foam in advance. Defoamers can effectively play a preventive effect.
2. Addition during the production process: When the foaming liquid is circulating or flowing, the circulating flow of the foaming liquid will consume the defoaming agent. In this case, use continuous dripping of the defoaming agent In the method, the defoamer can effectively exert the effect of eliminating foam, and it can also effectively control the additional amount to achieve the purpose of economic use of the defoamer.
