Product Details
CasNo： 63148-62-9
MF： C6H18OSi2
Appearance： liquid
Delivery Time： 15 days
Packing： 25kg/drum
Purity： 99%
Basic Information
- Chemical Composition: Organosilicon. This component endows it with excellent defoaming performance, which can quickly reduce the surface tension and thus destroy the stability of foam.
- Appearance: Usually a clear to slightly turbid liquid (the specific appearance may vary slightly due to factors such as production batches).
- Packaging Specifications: 25 kg/blue iron drum, 185 kg/blue iron drum. This packaging is convenient for storage and transportation, and the blue iron drum can better protect the product and prevent external factors from affecting the product quality.
Application Fields
- Protective Coating Systems: In protective coatings, such as industrial equipment protective paint and steel structure anti - corrosion paint, it can effectively eliminate foam generated during production and construction, avoid coating defects caused by foam, such as pinholes and bubbles, and improve the compactness and protective effect of the protective coating.
- Construction Coatings: Suitable for architectural exterior wall coatings, interior wall latex paints, etc. It can prevent the generation of foam during paint production mixing and coating construction (such as spraying and roller coating), ensure that the coating is uniform and smooth, and improve the decorativeness and durability of the paint.
- Wood and Furniture Coatings: Whether it is clear paint or colored paint, when coating the wood surface, it can quickly eliminate foam, make the coating adhere to the wood surface better, and present a smooth and flat appearance, improving the aesthetics and quality of woodware and furniture.
Performance Characteristics
- Efficient Defoaming and Foam Suppression: It has the ability of rapid defoaming and long - lasting foam suppression. It can eliminate the foam already generated in the system in a short time, and effectively inhibit the re - generation of foam in the subsequent production, storage and construction processes.
- Good Compatibility: It has good compatibility with various resins, additives and other components in solvent - based and solvent - free systems, and will not produce surface defects such as craters and fisheyes, ensuring the appearance quality of the coating.
- High Stability: Under normal temperature storage conditions, the product has good stability, is not easy to stratify or precipitate, and can maintain its defoaming performance for a long time.
Recommended Dosage
It usually accounts for 0.05% - 0.5% of the total formula dosage. The specific dosage needs to be adjusted according to the complexity of the coating system and the severity of foam generation. For example, for systems with serious foam generation, the dosage can be appropriately increased, but attention should also be paid to avoiding possible negative impacts caused by excessive dosage, such as affecting the gloss of the coating.
Storage and Transportation Conditions
- Transportation: Transport as non - hazardous chemicals. During transportation, collision and inversion should be avoided to prevent packaging damage and product leakage.
- Storage: It should be stored in a cool, dry and well - ventilated warehouse, avoiding direct sunlight and high - temperature environment. The recommended storage temperature is between 5 - 35℃, and the storage period is generally 24 months.
Usage Method
It can be added in the grinding stage, paint mixing stage or before construction of paint production. Adding it in the grinding stage can effectively inhibit the foam generated during pigment dispersion; adding it in the paint mixing stage can eliminate the foam formed by air introduced during the mixing process; adding it before construction can further ensure that the coating quality will not be affected by foam during construction. When adding, it should be fully stirred to make the defoamer evenly dispersed in the coating system.
