Product Details
- Product Name: Defoamer
- Brand and Model: BYK - 066N
- Packaging Specifications: 20 kg/blue iron drum, 155 kg/blue iron drum
- Main Ingredient: Organosilicon, which is processed through special techniques to play a stable and efficient role in defoaming systems.
Physical Properties
- Appearance: Usually a colorless to pale yellow transparent or translucent liquid. The specific appearance may vary slightly due to production batches and minor differences in raw materials.
- Density: Generally between 0.9 - 1.1 g/cm³ (The specific value is subject to the product technical manual).
- Flash Point: Relatively high, usually above 60°C, which is relatively safe during normal use and storage, reducing the risk of fire.
- Solubility: Can be well dispersed in various common solvent - based and solvent - free systems, ensuring uniform distribution and function in different systems.
Application Fields
- Solvent - free and Solvent - based Coatings: In the production of industrial protective coatings (such as steel structure anti - corrosion paint), architectural decorative coatings (interior and exterior wall latex paint, wood paint, etc.), it can effectively eliminate foam generated by air introduced during operations such as stirring and mixing, prevent defects such as pinholes and bubbles in the coating, improve the flatness and appearance of the coating, and enhance the protective performance of the coating on the substrate.
- Printing Inks: For various printing inks such as offset printing inks, gravure printing inks, and flexographic printing inks, during ink preparation and printing, it can quickly eliminate foam, ensure the leveling property and uniformity of the ink, make printed patterns clearer and colors more vivid, avoid printing defects caused by foam, and improve printing quality and production efficiency.
- Room - temperature Curing Plastic Systems Based on Epoxy Resin and Polyurethane: During plastic injection molding, compression molding and other forming processes, it can eliminate foam in the system, prevent problems such as voids and uneven surfaces in plastic products, and improve the mechanical properties and appearance quality of plastic products.
Performance Characteristics
- Efficient Defoaming and Long - lasting Foam Suppression: It has the ability to defoam quickly, can rapidly reduce the surface tension of foam, making the foam break quickly; at the same time, it has a good foam suppression effect, which can inhibit the re - generation of foam for a long time, ensuring the continuity and stability of the production process.
- Good Balance of Defoaming Property/Compatibility: While playing an efficient defoaming role, it has good compatibility with various components such as resins, pigments and additives in various solvent - based systems. It will not cause surface defects such as craters and fisheyes, nor will it affect key performance indicators such as curing performance, adhesion and gloss of coatings, inks or plastic systems.
- Wide Applicability: Suitable for various types of solvent - free and solvent - based systems. Whether it is a polar or non - polar system, it can show good defoaming effect and has strong adaptability to different formulations and production processes.
Recommended Dosage
Generally, it accounts for 0.05% - 0.5% of the total formula amount. The specific dosage will be adjusted according to factors such as the severity of foam in the system, solvent type and formula composition. For example, for systems that are prone to generate a large amount of foam, or application scenarios with extremely high defoaming effect requirements, the dosage can be appropriately increased; for systems with relatively mild foam problems, the dosage can be appropriately reduced.
Usage Method
- Adding Stage: It can be added in the grinding stage, paint (ink) mixing stage or mixing stage of coating, ink or plastic system production. Adding it in the grinding stage can effectively inhibit the foam generated during pigment dispersion; adding it in the paint (ink) mixing or mixing stage can eliminate the foam formed by air introduced during the mixing process.
- Adding Method: It is recommended to use the method of slow dripping while stirring to ensure that the defoamer can be evenly dispersed in the system and fully exert its defoaming performance. The stirring speed is generally controlled at 100 - 300 rpm, and the stirring time depends on the amount of the system and the efficiency of the stirring equipment, generally 15 - 30 minutes.
Storage and Transportation Conditions
- Transportation: Transport in accordance with the requirements for general chemicals. During transportation, collision, inversion, exposure to the sun and rain should be avoided to prevent packaging damage and affect product performance. It should be transported separately from strong oxidants, strong acids and strong alkalis.
- Storage: Store in a cool, dry and well - ventilated warehouse. The recommended storage temperature is controlled at 5 - 35°C, avoiding direct sunlight. When storing, it should be stored separately from incompatible substances, keep the packaging sealed. Under the specified storage conditions, the product storage period is generally 24 months.
Safety Information
- Health Hazards: If it comes into contact with the skin accidentally, rinse immediately with plenty of water; if it comes into contact with the eyes, rinse with plenty of water and seek medical attention in time. During use, avoid inhaling the gas volatilized from the product. It is recommended to operate in a well - ventilated environment. If necessary, personal protective equipment such as protective masks and gloves can be worn.
- Environmental Information: Waste packaging barrels and remaining products should be properly disposed of in accordance with local environmental protection regulations and should not be discarded at will. Under normal use and disposal conditions, this product has little harm to the environment.
