1. Basic Information

• Brand & Model: Defom W - 0506
• Core Ingredient: Organosilicon serves as the main active substance, combined with other functional additives to build an efficient defoaming system. The unique molecular structure of organosilicon endows it with excellent surface tension reduction ability, thus effectively achieving defoaming and foam inhibition.
• Appearance & Character: Usually a colorless to slightly yellow transparent liquid with good fluidity, without visible mechanical impurities to the naked eye, and easy to add and disperse in various water - based systems.
• Packaging Specification: 25 kg/blue square drum. The blue square drum is made of special materials, with good sealing, corrosion resistance and impact resistance, which can ensure that the product is not affected by external factors during transportation and storage, and avoid leakage, volatilization and deterioration.
• Physical Parameters:
  • Density: Approximately 0.98 - 1.02 g/cm³ (at 25℃), which is close to the density of common water - based systems, conducive to the uniform dispersion of the defoamer in the aqueous medium and giving full play to its defoaming effect.
  • Flash Point: ≥100℃, it is a flammable liquid. During storage and use, it should be kept away from open flames, high - temperature sources and strong oxidants to ensure safety.
  • Viscosity: 100 - 200 mPa·s (at 25℃). The moderate viscosity makes the defoamer easy to operate during stirring and mixing. It will not be difficult to disperse due to too high viscosity, nor will its stability in the system be affected due to too low viscosity.

2. Product Features

• Efficient Adaptability to Water - Based Systems: Specially developed and designed for water - based systems such as water - based coatings, water - based inks and water - based adhesives. It has good compatibility with water - based resins, additives, solvents and other components in these systems, and there will be no adverse phenomena such as demulsification, flocculation and delamination. It will not have a negative impact on key performance indicators such as film - forming performance, color, gloss and adhesion of the system.
• Rapid Defoaming and Long - Lasting Foam Inhibition: It can quickly penetrate to the liquid film surface of bubbles in the water - based system, reduce the surface tension of the liquid film, and make the bubbles burst quickly. At the same time, a stable protective film is formed in the system to continuously inhibit the generation of new bubbles. Even in dynamic construction processes such as stirring, spraying and brushing, it can maintain the low - foam state of the system for a long time to ensure the smooth progress of product production and construction.
• Good Chemical Stability: It can maintain stable defoaming and foam - inhibiting performance under different pH environments (usually in the range of pH 5 - 10) and different temperature conditions (generally between 5 - 40℃). It will not fail due to changes in the pH value or temperature fluctuations of the system, providing a reliable foam control solution for water - based systems.
• Low Addition Amount and High Cost - Effectiveness: Only a small amount (generally 0.05% - 0.3% based on the total formula mass) needs to be added to achieve the ideal defoaming and foam - inhibiting effect, which effectively reduces the user's use cost. Compared with some defoamers with poor effects that need to be added in large quantities to achieve similar effects, Defom W - 0506 significantly reduces the impact on system cost while ensuring performance.

3. Application Fields

• Water - Based Coatings Field: In the production process of various water - based coatings such as architectural latex paint, industrial water - based anti - corrosion paint and water - based wood coatings, it can effectively eliminate bubbles introduced by operations such as stirring, dispersing pigments and adding additives, as well as bubbles generated by spraying, roller coating and brushing during construction, making the coating surface smoother and smoother without defects such as pinholes and bubbles, and improving the decorative and protective properties of the coating.
• Water - Based Inks Field: Suitable for various water - based printing inks, such as paper printing ink, plastic film printing ink and fabric printing ink. It can eliminate bubbles generated during the production, storage and printing of ink in time, prevent quality problems such as blurring, missing printing and bubble holes in printed patterns, improve the clarity and quality of printed matter, and meet the needs of different printing processes.
• Water - Based Adhesives Field: In the production and use of water - based pressure - sensitive adhesives, water - based white latex and water - based polyurethane adhesives, it can quickly eliminate bubbles generated by processes such as stirring and emulsification, ensure the uniformity and stability of the adhesive, enable it to better wet the surface of the adherend during the bonding process, and improve the bonding strength and bonding effect.

4. Usage Methods & Recommended Dosage

• Recommended Dosage: Generally, 0.05% - 0.3% based on the total formula mass. The specific addition amount needs to be appropriately adjusted according to factors such as the foaming degree, viscosity, temperature and pH value of the water - based system. For systems with serious foaming, the dosage can be appropriately increased, but generally it should not exceed 0.5%; for systems with less foaming, the dosage can be reduced accordingly. It is recommended to determine the optimal addition amount through small - scale application tests.
• Addition Methods:
  • Direct Addition Method: When the water - based system is in a stirring state, slowly and evenly add Defom W - 0506 into the system, and continue stirring for 5 - 10 minutes to fully disperse the defoamer in the system. This method is simple to operate and suitable for most water - based systems.
  • Pre - dilution Method: If the viscosity of the water - based system is high, or it is necessary to control the addition amount of the defoamer more accurately, the defoamer can be pre - diluted with deionized water or other suitable water - based solvents in the system (the dilution ratio is generally 1:5 - 1:10), and then added to the system and stirred evenly. The pre - dilution method can improve the dispersion effect of the defoamer in high - viscosity systems and avoid the phenomenon of uneven local defoaming.

5. Storage & Safety

• Storage Conditions: Should be stored in a cool, dry and well - ventilated warehouse, avoiding direct sunlight and high - temperature environments. The storage temperature is recommended to be controlled at 5 - 35℃. The shelf life of the product in an unopened state is generally 12 - 18 months. After opening, it should be used as soon as possible. If it is not used up at one time, the packaging barrel should be sealed in time to prevent the product from volatilizing, absorbing moisture or reacting with substances in the air, resulting in performance degradation.
• Safety Precautions:
  • Operators should wear appropriate protective equipment such as protective gloves, goggles and masks when using the defoamer to prevent the product from contacting the skin and eyes. If it accidentally contacts the skin, it should be rinsed with plenty of water immediately; if it splashes into the eyes, it should be rinsed with plenty of water immediately and seek medical attention in time.
  • This product is a flammable liquid. Fireworks are strictly prohibited in storage and use places, and they should be kept away from open flames, high - temperature sources and electrostatic discharge sources. Necessary fire - fighting equipment such as dry powder fire extinguishers and carbon dioxide fire extinguishers should be equipped in accordance with relevant fire regulations to deal with possible fire accidents.
  • Avoid mixing, storing or transporting this defoamer with strong oxidants, strong acids and strong alkalis to prevent chemical reactions. During handling, handle with care to avoid damage to the packaging barrel due to impact or extrusion, resulting in product leakage.
