What are the applications of defoamers during discharge
After the polymerization reaction is completed, the reacted slurry should be discharged to the discharge tank, and the unreacted VCM should be discharged. When the unreacted gas is discharged, a large amount of foam will be generated in the discharge chute. These foam will be discharged with the unr

How dangerous is the foaming of leveling agents? Why not use leveling agents and defoamers?
Leveling agent is a commonly used coating additive and one of the important varieties in the coating industry. Leveling agent can promote the formation of a flat, smooth, and uniform coating film during the drying and film-forming process of the coating, effectively reducing the surface tension of t

How to achieve the equilibrium state of leveling agent and defoamer in water-based coatings
Some manufacturers in the development of water-based coatings always encounter the problem of multi foam and poor surface smoothness due to the imbalance between defoamer and leveling agent. During the use of water-based coatings, both defoamers and leveling agents need to be added in order to achie

Introduction to the dosage and steps of adding defoamers to coatings
The dosage and efficacy of defoamers depend on the formulation system of the coating or ink defoamer, especially the type of polymer, pH value, pigment dosage, and the chemical structure of other additives used. Similarly, there are requirements for the type and dosage of defoamers in the manufactur

Characteristics and functions of defoamers used as additives in coatings
Defoamer is widely used at present, and its main function is to eliminate some harmful foam. And in the process of preparing some water-based coatings, defoamers are also needed, just like other additives such as dispersants and leveling agents, which play an auxiliary role in the coating production
