Defoamer

We encounter foam in many aspects of our lives. We see it not only in soap, shampoo, and detergent but also in various food and beverages. This foam does not create big problems for us. However, when foam occurs in industry fields, it may create multiple problems in the exterior and properties such as appearance defects, layer separation, and lowered dispersion. To solve this problem, there is generally a mechanic method and a chemical method. Our company’s defoaming agent is the chemical method, and it can defoam liquids with just a small amount. Foam is chemically removed in three ways, destruction, where foam is destroyed when a defoaming agent is input, suppression, where the defoaming agent suppresses the foam, and degassing, where the foam is merged. Our defoaming agents are widely used in various sectors and are divided into silicone types, mineral oil types, and polymer types. As there is an increasing demand for antifoaming agents, we are continuously developing new products.
Industry / Field
Product Features
Paint & Ink

In the paint and coating field, form may cause aesthetic problems such as craters and pinholes or even cause corrosion and adhesion problems on the painted surface. Our defoamers are applied to various water- and oil-based paints, inks, adhesives, emulsions, and finishing materials to solve the above problems.

Electronic
material

Air bubbles generated when manufacturing various electronic material slurries may lead to poor productivity and quality. We provide defoamers for relevant environments and fields of use to solve these problems and contribute to higher-quality products.

Rubber/latex

A large amount of surfactant involved in the emulsion and latex processes often causes foaming. Defoamers are necessary as additives to suppress foaming in each process stage from manufacturing to final product completion. Also, dispersion is an essential property when adding defoamers to emulsions and latex processes. If the dispersion capacity of a defoamer is inadequate, fat components may become suspended on the surface during the latex and emulsion processes, hampering final product quality. San Nopco Korea helps ensure the highest quality by selecting the best products suitable for the emulsion/latex (mainly monomer stripping), filling, transporting, and final coating processes.

Ceramic

Defoamers are essential for suppressing the possibility of bubbles forming on the binders for controlling aqueous slurry during ceramic manufacturing. Defoamers designed using various materials such as polyether and mineral oil with amide wax as the core material can be used without affecting the specificity of fine ceramic, electrical, and magnetic functions.

Paper

Our various types of defoamers inhibit the generation of air bubbles which may lower productivity and quality in the pulp and paper manufacturing process. Defoamers for kraft pulp manufacturing, coating and size press, and wastewater processing are deployed for each process.

Concrete/
construction
materials

Defoamers are essential for controlling the air volume of cement, mortar, and concrete products. Our defoamers secure excellent performance in preventing excessive air inflow and maintaining proper air volume. Excessive shrinkage or porosity related to cement and concrete production is prevented by removing air layers.

Defoamer [Defoamer Theory]

  • Defoaming Mechanism (1) Foam breaking : Destroyed by penetrating into the upper bubble
  • Defoaming Mechanism (2) Foam inhibition : Inhibits bubble formation by penetrating into the bubbles in the liquid
  • Defoaming Mechanism (3) Deairation : Floating to the liquid surface by coalescing air bubbles in the liquid
