Product Details

• Product Name: Defoamer
• Brand and Model: BYK - 070
• Packaging Specifications: 25 kg/blue iron drum. This packaging is convenient for handling and storage, suitable for small and medium - sized enterprises and laboratories with relatively small product demand, and can effectively reduce waste during storage and use.
• Main Ingredient: Organosilicon polymer. Through a special synthesis process, organosilicon monomers are polymerized to form a polymer with a unique molecular structure, which endows the product with efficient defoaming and deaeration performance.

Physical Properties

• Appearance: Usually a colorless to light yellow transparent or translucent liquid. There may be extremely slight color changes between different production batches due to small differences in raw materials, but this will not affect the performance and use effect of the product.
• Density: Approximately 0.9 - 1.1 g/cm³, which is similar to the density of common adhesives, sealants and acrylic system materials. This enables BYK - 070 to be dispersed relatively uniformly when added to these systems, better exerting defoaming and deaeration effects.
• Flash Point: Relatively high, generally above 60 °C. It is relatively safe in normal storage and use environments, and is not prone to dangerous situations such as combustion.
• Solubility: It can be well dissolved or dispersed in various organic solvents, such as aromatic hydrocarbons and ester solvents; In aqueous systems, good dispersion can also be achieved through special emulsification technology, thus adapting to different types of adhesives, sealants and acrylic systems.

Application Fields

• Adhesives: During the production of adhesives, operations such as stirring and adding various additives are likely to introduce air and form foam. These foams will affect the uniformity, fluidity and bonding performance of adhesives. BYK - 070 can quickly eliminate these foams, and continuously inhibit the generation of new foams during the construction of adhesives, ensuring that the adhesives can be evenly coated and achieve good bonding effect.
• Sealants: Sealants also face the problem of foam during production and construction. The existence of foam will lead to air pockets inside the sealant, affecting the sealing effect and reducing its waterproof, dust - proof and other properties. BYK - 070 can effectively prevent the generation of foam and air pockets, make the sealant form a dense sealing layer, and improve its sealing performance and service life.
• Room - temperature Curing Acrylic Systems: Acrylate materials are widely used in coatings, inks, resins and other fields. During room - temperature curing, chemical reactions inside the system and operations such as stirring are prone to generate foam. BYK - 070 is especially suitable for this system. It can efficiently eliminate foam without affecting the curing performance of the acrylic system, ensure the surface quality of coatings, paint films, etc., and avoid defects such as pinholes and bubbles.

Performance Characteristics

• Efficient Defoaming and Deaeration: It has the ability of rapid defoaming and deaeration, and can quickly reduce the surface tension of foam, making the foam burst quickly. At the same time, it can also effectively remove the tiny air pockets already existing in the system, improving the compactness and uniformity of materials.
• Good System Compatibility: It has good compatibility with various components in adhesives, sealants and acrylic systems, such as resins, curing agents and fillers. It will not have adverse reactions with these components, nor will it affect key performance indicators such as curing speed, hardness and flexibility of the system.
• Strong Targeting: It has particularly outstanding effects on acrylate systems, and can accurately solve the problems of foam and air pockets encountered in the production and construction of this system, meeting the high - quality requirements of users for acrylate products.

Recommended Dosage

Generally, it accounts for 0.05% - 0.5% of the total formula amount. The specific usage amount needs to be adjusted according to factors such as the severity of foam in the system and the formula composition. If the system is prone to generate a large amount of foam or has very high requirements for defoaming effect, the dosage can be appropriately increased; Conversely, if the foam problem of the system is relatively light, the dosage can be appropriately reduced. It is recommended to conduct a small - scale test before actual use to determine the optimal addition amount.

Usage Method

• Adding Stage: During the production process of adhesives, sealants or acrylic systems, it is recommended to add at the later stage of stirring or the glue (paint) mixing stage. Adding at the later stage of stirring can eliminate most of the foam generated during the stirring process; Adding at the glue (paint) mixing stage can further remove the new foam introduced during the mixing process.
• Adding Method: Adopt the method of slow dripping while stirring, and the stirring speed is controlled at 100 - 300 rpm. Slow dripping can ensure that the defoamer is evenly dispersed into the system, avoiding excessive local concentration; Continuous stirring can make the defoamer fully mix with the system, better exerting defoaming and deaeration effects.

Storage and Transportation Conditions

• Transportation: Transport in accordance with the requirements for general chemicals. During transportation, it is necessary to prevent the packaging barrels from being collided or extruded, and avoid product leakage caused by packaging damage. At the same time, it should be avoided to be transported together with strong oxidants, strong acids, strong bases and other substances to prevent chemical reactions.
• Storage: It should be stored in a cool, dry and well - ventilated warehouse. The recommended storage temperature is controlled at 5 - 35 °C, and direct sunlight should be avoided. The packaging barrel should be kept sealed to prevent the product from volatilizing or mixing with impurities, which will affect the product quality. Under the condition of meeting the storage conditions, the storage period of the product is generally 24 months.

Safety Information

• Health Hazards: If it accidentally contacts the skin, it should be rinsed with plenty of water immediately; If it contacts the eyes, it needs to be rinsed 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.
