1. Basic Information

• Brand & Model: Defom 6800
• Core Ingredient: Silicone serves as the main active component, combined with specific additives to form an efficient defoaming system. The unique molecular structure of silicone can significantly reduce the surface tension of liquids, thereby achieving the purpose of defoaming and foam inhibition.
• Appearance & Character: Usually a colorless to light yellow transparent liquid with good fluidity, without visible impurities or suspended matter to the naked eye, and easy to disperse evenly in various systems.
• Packaging Specification: 25 kg/blue iron drum. The iron drum has good sealing and corrosion resistance, which can effectively protect the product from external factors during transportation and storage, and prevent the product from volatilizing, deteriorating or leaking.
• Physical Parameters:
  • Density: Approximately 0.95 - 1.05 g/cm³ (at 25℃), similar to the density of most oily and some water-based systems, which is conducive to the uniform distribution of the defoamer in the system and fully exerts its effect.
  • Flash Point: ≥100℃, it is a flammable liquid. It should be kept away from open flames, high-temperature sources and strong oxidants during storage and use to avoid safety accidents such as fire.
  • Viscosity: 150 - 350 mPa·s (at 25℃). The moderate viscosity makes the defoamer easy to mix with the system during stirring, and will not affect the defoaming effect and use convenience due to too high or too low viscosity.

2. Product Features

• Wide System Applicability: Suitable for various coating and ink systems, such as floor coatings, epoxy systems, UV varnishes, screen printing inks, unsaturated polyester systems, etc. Whether it is water-based, oily or solvent-free systems, it can show good defoaming and foam-inhibiting properties, providing a universal solution for customers in different fields.
• Efficient Defoaming and Foam-Inhibiting Ability: It has excellent elimination and inhibition effects on bubbles generated in high-viscosity resin systems and during construction. Especially in the manufacturing and construction of high-solid and solvent-free epoxy coatings, it can quickly eliminate bubbles generated by stirring, curing reaction, etc., and prevent bubbles from remaining in the coating to cause defects such as pinholes and fish eyes, ensuring the flatness and aesthetics of the coating.
• Adaptability to High Film Thickness Construction: For high-viscosity, high-film-thickness, especially solvent-free high-film-thickness epoxy floor coatings, Defom 6800 can effectively inhibit the generation and floating of bubbles, avoiding the impact of bubble problems on the thickness uniformity and overall performance of the coating, and meeting the high-standard floor construction requirements.
• Good Chemical Stability: Under different chemical environments, such as acid-base conditions and different solvent systems, it can maintain stable performance and will not chemically react with other components in the system to affect the defoaming effect or cause the system performance to decline.

3. Application Fields

• Floor Coating Field: In the production and construction of epoxy floor coatings, polyurethane floor coatings, etc., Defom 6800 can effectively eliminate bubbles, ensure that the floor surface is smooth and smooth, improve wear resistance, corrosion resistance and aesthetics, and is widely used in various floor projects such as industrial plants, commercial places, and parking lots.
• Epoxy System: In the synthesis of epoxy resin, paint preparation and curing process, the defoamer can quickly eliminate bubbles and ensure the quality of epoxy products, such as epoxy electronic potting glue, epoxy structural glue, epoxy anti-corrosion coating, etc.
• Ink Field: In the production and printing process of UV varnish, screen printing ink, etc., it can eliminate bubbles in the ink in time, prevent problems such as blurring, missing printing, and bubble holes in printed patterns, and improve the clarity and quality of printed matter.
• Unsaturated Polyester System: Used in the processing and molding of unsaturated polyester resin, such as the production of FRP products, to eliminate bubbles in the resin and improve the strength and appearance quality of the products.

4. Usage Methods & Recommended Dosage

• Recommended Dosage: Generally 0.1% - 0.5% based on the total formula. The specific dosage needs to be adjusted according to factors such as the foaming degree, viscosity and temperature of the system. For high-viscosity systems with serious foaming, the dosage can be appropriately increased, but it should not exceed 1%. It is recommended to determine the optimal addition amount through small-scale tests.
• Addition Methods:
  • Direct Addition Method: Under the stirring state of the system, slowly and evenly add Defom 6800 into the system, and continue stirring for 5 - 15 minutes to fully disperse the defoamer. This method is simple to operate and suitable for most conventional systems.
  • Pre-dilution Method: If the system viscosity is high, the defoamer can be pre-diluted with the solvent in the system (such as xylene, ethyl acetate, etc.) at a ratio of 1:5 - 1:10 first, and then added to the system. This can improve the dispersion effect of the defoamer and avoid local agglomeration.

5. Storage & Safety

• Storage Conditions: Should be stored in a cool, dry and well-ventilated warehouse, avoiding direct sunlight and high-temperature environments. The recommended storage temperature is 5 - 35℃. The shelf life of unopened products is generally 12 - 18 months. After opening, it should be used as soon as possible. If it is not used up at one time, it should be sealed and stored to prevent the product from volatilizing, absorbing moisture or reacting with substances in the air and deteriorating.
• Safety Precautions:
  • Protective gloves, goggles and masks should be worn during operation to avoid skin contact and inhalation. 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 corresponding fire-fighting equipment, such as dry powder fire extinguishers, should be equipped.
  • Avoid mixed storage and transportation with strong oxidants, strong acids, strong alkalis and other substances to prevent chemical reactions. During handling, handle with care to prevent the packaging drum from 破裂 and causing product leakage.
