In order to avoid the shrinkage phenomenon of the coating due to excessive addition of defoamer, the following key aspects can be taken into consideration:1. Accurately measure and control the dosageExperimentally determine the optimal dosage:Before formal production, it is imperative to deter

The relationship between defoamer dosage and paint shrinkageIn the production and use of paint, defoamer plays a vital role. It can effectively eliminate bubbles generated during the manufacture and construction of paint, and improve the quality and construction effect of paint. However, the dosage

The role of dispersants in coatingsAs an indispensable material in modern industrial production and daily life, the performance and quality of coatings directly affect the appearance, durability and environmental protection of products. In the preparation process of coatings, dispersants, as a key a

The wonderful effect of coating levelling agent addition on performanceCoatings play an important role in our lives, from home decoration to industrial protection, and the amount of leveling agent added is one of the key factors that affect the final performance of the coating, just like the amount

Usually, surfactants are associated with other additives, such as dispersants, so why are they different? In fact, surfactants are a wide range of categories, including many auxiliary agents, and dispersants are also surfactants. However, it should be noted that inorganic dispersants are all surfact

Defoamers, also known as antifoams, will produce many harmful foam in the process of industrial production, so defoamers need to be added. But there are many types of defoamers, including organosiloxanes, polyethers, silicon and ether grafts, amines, imines, and amides, which have the characteristic

The main difference between dispersants and surfactants is that dispersants can improve particle separation in suspensions, while surfactants are substances that can reduce surface tension between two phases of a substance.Dispersant is a form of surfactant. But all surfactants are not dispersants.

The characteristics of defoamers for landfill leachate are as follows:1. The defoaming and defoaming effect of leachate treatment is significant, and the dosage is small, which will not affect the properties of the foaming system itself;2. It can remove various forms of foam, such as biological bact

Polyether defoamer1. Polyether type defoamers are formed by the polymerization of ethylene oxide (EO) and propylene oxide (PO) under certain conditions, using a substance containing active hydrogen as the starting agent. According to different application fields, there are specific requirements for

The adhesion promoter is a new type of resin based adhesion promoter that has special effects on the anti peeling property of coatings. Adhesion promoters are widely used in various substrates such as chemical fibers, wood, plastics, metals, ceramics, glass, ABS, PVC, and other substrates. They were

The application of alternative solvent based products in various fields. Waterborne polyurethane, as a representative, can be widely used in coatings, adhesives, fabric coatings and finishing agents, leather finishing agents, paper surface treatment agents, and fiber surface treatment agents.Waterbo
