Product Details
- Product Name: Defoamer
- Brand and Model: BYK - 052N
- Packaging Specifications: 20 kg/blue iron drum, 150 kg/blue iron drum
- Composition: Non - silicon polymer (The specific chemical structure is not fully disclosed due to technical confidentiality and other reasons. It is mainly made through a special synthesis process and has efficient defoaming function.)
Physical Properties
- Appearance: Usually a colorless to pale yellow clear liquid (The appearance of different batches may vary slightly due to minor differences in raw materials.)
- Density: Approximately 0.8 - 1.0 g/cm³ (The specific value is subject to the accompanying technical data of the product.)
- Flash Point: Relatively high, generally above 60°C (To ensure safety during production and use.)
- Solubility: Can be well dispersed in most common solvent - based and some solvent - free systems.
Application Fields
- Solvent - based printing inks: In the production process of offset printing inks, gravure printing inks, flexographic printing inks, etc., it can effectively eliminate foam introduced by operations such as stirring and adding pigments, ensure the leveling property and uniformity of the ink, and make the printed patterns clearer and the colors more vivid.
- Solvent - free printing inks: Suitable for some environmentally friendly solvent - free ink systems, solve the foam problem in the system, and meet the needs of the modern printing industry for environmental protection and high efficiency.
- Varnishes: Whether it is solvent - based varnish or solvent - free varnish, using this defoamer can avoid defects such as bubbles and pinholes after varnishing, improve the gloss and surface quality of the coating, and enhance the protection effect on the substrate.
- Other solvent - based and solvent - free coatings: It can be used as a general defoamer in industrial protective coatings, wood coatings, etc., to ensure the stability of coatings during production and coating processes.
Performance Characteristics
- Rapid foam breaking: It can quickly penetrate into the foam film, destroy the surface tension of the foam, and make the foam break quickly. Compared with some similar products, the defoaming speed is faster, which can effectively shorten the production time.
- Long - lasting foam suppression: It can not only quickly eliminate the generated foam, but also inhibit the regeneration of foam for a long time, ensure the continuity of the production process and construction process, and reduce downtime and rework caused by foam problems.
- Good compatibility: It can be well compatible with various resins (such as acrylic resin, polyurethane resin, etc.) and additives (such as leveling agent, dispersant, etc.) in solvent - based and solvent - free systems, and there will be no surface defects such as craters and fisheyes, ensuring the appearance quality of the coating.
- Does not affect interlayer adhesion: In multi - layer coating systems, after using this defoamer, it will not have a negative impact on the adhesion between coatings, ensuring a firm bond between coatings and improving the overall durability and reliability of the coating.
Recommended Dosage
It generally accounts for 0.05% - 0.5% of the total formula amount. The specific dosage needs to be adjusted according to factors such as the severity of foam in the system and the formula composition. For example, for ink formulas that are prone to generate a large amount of foam, or situations where a lot of air is easily introduced in the production environment, the dosage can be appropriately increased; for systems with relatively mild foam problems, the dosage can be reduced.
Usage Method
- Adding stage: It can be added in the grinding stage and paint (ink) mixing stage of ink or coating production. Adding it in the grinding stage can effectively inhibit the foam generated during pigment dispersion; adding it in the paint (ink) mixing stage can eliminate the foam generated during the mixing process.
- Adding method: It is added slowly while stirring to ensure that the defoamer can be evenly dispersed in the system and exert the best defoaming effect. 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 as general chemicals, and avoid mixing with strong oxidants, strong acids, strong alkalis and other substances. During transportation, collision, inversion, exposure to the sun and rain should be prevented to ensure that the packaging is intact.
- Storage: It should be stored in a cool, dry and well - ventilated warehouse, with the temperature controlled at 5 - 35°C, avoiding direct sunlight. When storing, it should be stored separately from incompatible substances, keep the packaging sealed, and the 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 volatile gases. 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: Under normal use and disposal conditions, this product has less harm to the environment, but 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.
