1. Basic Information

• Brand & Model: Defom W-082
• Core Ingredient: Based on mineral oil, formulated with special surfactants and additives to ensure high-efficiency defoaming performance
• Appearance & Character: Typically appears as a clear or translucent oily liquid, ranging in color from light yellow to light brown, with no obvious mechanical impurities
• Packaging Specification: Standard packaging is 50 kg/blue round drum; customized packaging of different specifications is also available upon customer request
• Physical Parameters:
  • Density: Approximately 0.85 - 0.95 g/cm³ (at 20℃), ensuring appropriate dispersion and defoaming effects in the system
  • Flash Point: Relatively high, usually ≥130℃, classified as a relatively safe non-flammable substance
  • pH Value: Neutral, ranging from 6 to 8, compatible with various water-based systems without easily affecting the acidity or alkalinity of the system

2. Product Characteristics

• High-Efficiency Defoaming Ability: It can quickly eliminate foam in water-based systems. Through the synergistic effect of mineral oil and surfactants, it rapidly reduces the surface tension of foam to break it; at the same time, it inhibits the generation of new foam, ensuring the system remains in a low-foam state during production, stirring, and construction processes.
• Wide System Applicability: Specifically designed for water-based systems, it performs excellently in fields such as latex paints, water-based adhesives, papermaking slurries, and water-based corrugated ink. It has good compatibility with different resin types, pigment systems, and other additives, without affecting key properties of the system such as stability, film-forming ability, and bonding strength.
• Long-Lasting Foam Inhibition Performance: After being added to the system, it can continuously exert foam-inhibiting effects for a long time. Even if the system is affected by external factors (such as temperature changes, mechanical stirring), it can still effectively control foam generation and reduce product quality defects caused by foam problems.
• Good Dispersibility: It can disperse quickly in water-based systems without complex dispersion processes. It can be uniformly mixed through simple stirring, saving production time and costs while ensuring the defoamer exerts its effects evenly.

3. Application Fields

• Latex Paint Industry: During the production of latex paints, it effectively eliminates foam introduced by operations such as stirring and adding pigments/fillers, avoiding surface defects like pinholes, bubbles, and craters on the coating. It improves the smoothness and decorativeness of the coating, while ensuring the latex paint maintains good fluidity and stability during storage and construction.
• Water-Based Adhesive Industry: Used in products such as water-based white latex and water-based polyurethane adhesives, it prevents problems like volume expansion and unstable viscosity of the adhesive caused by foam during production. It ensures the adhesive is evenly distributed during coating and improves the bonding effect on different materials (such as paper, wood, and plastic).
• Papermaking Slurry Industry: It can quickly eliminate foam in papermaking slurries, avoiding foam from affecting the forming quality of paper and preventing paper defects like holes and spots. It improves the uniformity and strength of paper, and also helps enhance the operating efficiency of paper machines, reducing production failures such as paper breaks caused by foam.
• Water-Based Corrugated Ink Industry: During the preparation and printing of water-based corrugated ink, it effectively controls foam generation, ensuring the ink is evenly transferred to the surface of corrugated paper. It avoids problems like blurring, missing prints, and color differences in printed patterns, improving the quality and aesthetics of corrugated printed products.

4. Usage Method & Recommended Dosage

• Recommended Dosage: Based on the total formula, the dosage generally ranges from 0.1% to 0.5%. The actual dosage needs to be accurately adjusted through tests according to the foaming degree of the specific system, production process, and requirements for defoaming effects.
• Addition Method:
  • Direct Addition Method: Under stirring, slowly and evenly add Defom W-082 to the system, and continue stirring for 5 - 10 minutes to ensure the defoamer is fully dispersed. Suitable for small-scale production or situations where there is no strict requirement on the addition time.
  • Dilution Addition Method: Pre-dilute the defoamer with an appropriate amount of water or system solvent by 2 - 5 times, then add it to the system. This method helps improve the dispersion effect of the defoamer in the system and is suitable for large-scale production or systems with high requirements for defoamer dispersibility.

5. Storage & Safety

• Storage Conditions: Should be stored in a cool, dry, and well-ventilated warehouse, protected from direct sunlight and high-temperature environments. The recommended storage temperature is 5 - 35℃ to prevent the product's performance from being affected by excessively high or low temperatures. Under proper storage conditions, the shelf life of the product is usually 12 - 18 months.
• Safety Precautions: Although the product is non-flammable, it is still necessary to avoid contact with open flames and high temperatures during use; it is recommended that operators wear protective gloves and goggles to prevent the product from contacting the skin and eyes. In case of accidental contact, rinse immediately with plenty of water and seek medical attention promptly. The product is non-edible and should be stored away from children.
