Organic Silicone Defoamer

Many factors, such as materials and construction techniques, affect the concrete forming process, often creating bubbles on the surface. The presence of air bubbles on the cover not only affects the aesthetics of the component but also has a particular impact on the durability of the concrete. At this time, defoaming treatment with more bubbles must be performed on the concrete surface. Organic silicone defoamers can effectively reduce the formation of bubbles and foam in construction materials such as concrete and mortar. The pores in the material can be decreased by controlling the generation and diffusion of bubbles, which can improve the compactness and strength of the material.

Feature:

1. Suitable for defoaming under solid acid and alkali conditions;
2. It can maintain good physical condition in a wide temperature range. It will not break emulsions and has stronger foam breaking and defoaming effects than average temperature. Quickly defoaming and suppressing foam for a long time;
3. Good dispersion in cement mortar system and rapid defoaming;
4. Non-toxic, no irritating odor, no adverse side effects, and will not cause any pollution to the environment. Add a small amount when using this product to defoam. It is a product with good quality and a favorable price.

The use of organic silicone defoamers in building materials offers several specific advantages, some of which are:

Reduce bubble porosity:

Improve process performance: Organic silicone defoamers can improve process performance during the preparation of building materials. They reduce the material’s viscosity and surface tension, enhancing flow and workability and making the material easier to pour, smooth, and form.

Improve material properties: Organic silicone defoamers can improve building materials’ physical and mechanical properties. The compressive strength, flexural strength, and durability of the material can be enhanced by controlling the distribution and shape of bubbles. In addition, defoaming agents can improve the material’s thermal insulation and acoustic properties.

Improve the appearance quality of materials: Organic silicone defoamer can improve the appearance quality of building materials. They can reduce or eliminate bubbles, defects, and pores on the material surface, making it smoother, more uniform, and beautiful.

Increase material durability: Organic silicone defoamers can improve the durability of building materials. By reducing bubbles and pores, the penetration of water and gas can be reduced, thereby reducing the material’s moisture absorption rate, water permeability, and gas permeability and extending the material’s service life.

Features of organic silicone defoamer:

Organic silicone defoamer is a surfactant with a unique molecular structure. Its molecular structure contains silicon-oxygen bonds, so it has the following characteristics:

1. Excellent defoaming performance: The silicon-oxygen bond in organic silicone defoamer molecule forms a stable silicon oxide film in water, thereby effectively inhibiting the formation and diffusion of bubbles and having excellent defoaming performance.
2. High-temperature resistance: The thermal stability of the silicon oxide film is excellent and can remain stable at high temperatures so that organic silicone defoamer can be used under high-temperature conditions.
3. Good stability: The silicon-oxygen bond in the organic silicone defoamer molecule gives it good strength and is not easily decomposed or hydrolyzed by water.
4. Good compatibility with other surfactants: Organic silicone defoamer can be compatible with other surfactants to create synergistic effects.
