1. Basic Information

• Brand & Model: DAPR ODF1760
• Core Ingredient: Modified polyol, a component obtained by optimizing the molecular structure of polyols through specific chemical modification processes. Its molecular structure contains both lipophilic and hydrophilic groups, enabling it to quickly penetrate the surface of the bubble film, reduce the film’s surface tension, and destroy its stability—thus achieving defoaming and foam-inhibiting effects. Since it contains no silicon, it avoids surface defects that may be caused by silicone-based defoamers.
• Appearance & Character: Typically a colorless to light yellow transparent liquid with good fluidity, free from visible mechanical impurities to the naked eye. It disperses evenly in various coatings and UV systems easily, without affecting the color or transparency of the final product due to its appearance properties.
• Packaging Specification: 25 kg/drum. High-strength, corrosion-resistant packaging drums are used, featuring excellent sealing and impact resistance. They effectively prevent product leakage, volatilization, or external contamination during transportation and storage, ensuring stable product performance.
• Physical Parameters:
  • Density: Approximately 1.02 - 1.10 g/cm³ (at 25℃), close to the density of most coatings and UV systems. This facilitates uniform diffusion in the system, allowing it to fully exert its defoaming effect.
  • Flash Point: ≥70℃, classified as a non-flammable liquid. This reduces safety risks during storage and use, enabling easy daily operation and management.
  • Viscosity: 200 - 800 mPa·s (at 25℃). The moderate viscosity range not only allows for accurate metered addition but also ensures rapid dispersion in target systems of different viscosities, avoiding local aggregation that could affect defoaming efficiency.

2. Product Features

• Significant Silicon-Free Advantage: As a silicon-free defoamer, it completely avoids surface defects such as coating craters, fisheyes, and reduced gloss that may be caused by silicone-based defoamers. It is particularly suitable for scenarios with high requirements for coating appearance, such as can coatings, automotive original equipment manufacturer (OEM) paints, and automotive refinish paints—ensuring the product surface is smooth, flat, and uniformly colored.
• Dual Efficiency in Defoaming and Foam Inhibition: The modified polyol component can quickly capture and eliminate existing bubbles in the system, while forming a stable protective film on the system surface to inhibit the generation of new bubbles. It effectively controls foaming during coating production (e.g., stirring) and application (e.g., brushing, spraying), with long-lasting foam-inhibiting effects to maintain long-term system stability.
• Broad System Compatibility: It exhibits excellent compatibility with acidic/alkaline systems of can coatings, high-solid systems of automotive coatings, anti-corrosion components of industrial protective coatings, high-temperature curing systems of coil coatings, film-forming resins of wood coatings, water-based matrices of water-based inks, and photo-curing resins of UV systems. It does not react with other components in the system, nor does it cause turbidity or delamination—ensuring the original performance of the product remains unaffected.
• Adaptability to Diverse Application Scenarios: It not only meets the defoaming needs of conventional coatings but also adapts to special scenarios, such as the food contact safety requirements of can coatings, the high-temperature baking process of automotive OEM paints, and the rapid curing characteristics of UV systems. It performs stably under different process conditions, eliminating the need to replace defoamer types due to scenario changes.

3. Application Fields

• Can Coatings Field: Suitable for internal and external coatings of various metal cans. It eliminates bubbles generated during coating application and curing, avoiding issues such as uneven coating thickness and reduced anti-corrosion performance caused by bubbles. Its safe and stable composition also meets food contact standards.
• Automotive Coatings Field: Applicable to electrophoretic paints, intermediate coats, topcoats of automotive OEM paints, and the entire range of automotive refinish paints. It ensures automotive body coatings are free of bubbles and defects, enhancing the decorative and weather-resistant properties of the coatings to meet the strict appearance and performance requirements of the automotive industry.
• Industrial Protective Coatings Field: It functions in protective coatings for industrial components such as steel structures, mechanical equipment, and pipelines. By eliminating bubbles in the coatings, it ensures the coatings adhere tightly to the substrate surface, enhancing the coatings’ corrosion resistance, wear resistance, and impact resistance—extending the service life of industrial components.
• Coil Coatings Field: It adapts to the continuous roll coating and high-temperature baking processes of coil coatings. It effectively inhibits bubbles generated by high-speed shear during roll coating and bubbles formed by solvent evaporation during baking, ensuring the flatness and consistency of coil coatings to meet the appearance and performance needs of the construction and home appliance industries.
• Wood Coatings Field: Used in the coating of wood products such as solid wood furniture and wood-based panels. It eliminates bubbles during brushing or spraying of the coating, avoiding defects such as pinholes and pitting on the wood surface, enhancing the decorative effect and feel of the wood coating, while not affecting the coating’s display of wood grain.
• Water-Based Inks & UV Systems Field: In water-based ink printing (e.g., packaging printing, paper printing), it eliminates bubbles generated during ink stirring and transfer, ensuring clear printed patterns and vivid colors. In UV-curable coatings and ink systems, it adapts to the rapid curing process, quickly defoaming before curing to ensure the surface quality and performance of the cured product.

4. Usage Methods & Recommended Dosage

• Recommended Dosage: 0.1% - 0.8% based on the total mass of the formula. The specific dosage needs to be adjusted flexibly according to factors such as the type of target system (e.g., coating, water-based ink, UV system), foaming degree, and application process (e.g., brushing, spraying, roll coating). For example, in high-foaming automotive OEM intermediate coat systems, the dosage can be appropriately increased to 0.6% - 0.8%; in low-foaming systems such as water-based inks, the dosage can be controlled between 0.1% - 0.3%. It is recommended to determine the optimal dosage through small-scale formula tests to achieve the ideal defoaming effect.
• Addition Methods:
  • Direct Addition Method: When the target system (e.g., coating, water-based ink) is under stirring (stirring speed recommended at 300 - 500 r/min), slowly and evenly add DAPR ODF1760 to the system, and continue stirring for 15 - 30 minutes to ensure the defoamer fully integrates with the system without local aggregation. This method is easy to operate and suitable for most conventional systems.
  • Pre-Dilution Method: For high-viscosity target systems (e.g., high-solid automotive coatings), the defoamer can first be pre-diluted with a compatible solvent in the system (e.g., coating solvent, water for water-based inks) at a ratio of 1:5 - 1:10. After stirring evenly, add the diluted solution slowly to the target system and continue stirring for 20 - 30 minutes. Pre-dilution improves the dispersion efficiency of the defoamer in high-viscosity systems, avoiding poor local defoaming effects or new defects caused by uneven defoamer dispersion.

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 should be controlled between 5 - 40℃. The warehouse must be kept away from fire sources, heat sources, and strong oxidants to prevent performance changes due to environmental factors. Unopened products have a shelf life of 18 months under proper storage conditions; after opening, the packaging drum must be sealed immediately to prevent the product from absorbing moisture or oxidizing due to prolonged contact with air (which would affect defoaming performance). Opened products are recommended to be used up within 3 months.
• Safety Precautions:
  • Operators must wear protective gloves, goggles, and masks during use to avoid direct contact between the product and skin/eyes. In case of accidental skin contact, rinse immediately with plenty of water; if splashed into the eyes, rinse with physiological saline for at least 15 minutes and seek medical attention promptly.
  • Although the product is non-flammable, the storage and use areas must still maintain good ventilation to prevent excessive accumulation of product vapor. Smoking or open flame operations are strictly prohibited in the storage area, and dry powder fire extinguishers and other fire-fighting equipment should be equipped to handle emergencies.
  • When handling the product, carry it with care to avoid damage to the packaging drum due to impact or extrusion (which could lead to product leakage). In case of leakage, isolate the leakage area immediately, absorb the leaked material with adsorbents (e.g., vermiculite, sand), and dispose of it properly in accordance with environmental protection requirements—do not discharge it randomly.
