1. Basic Information

• Brand & Model: RHEOLATE 299
• Core Ingredient: Associative polyurethane, a specially structured high - molecular polymer. It regulates rheological properties through the associative interaction between functional groups on its molecular chain and other components (such as resins and pigments) in aqueous systems.
• Appearance & Character: Typically a colorless to slightly yellow transparent or translucent liquid with moderate fluidity, free from visible mechanical impurities to the naked eye. This makes it convenient to be added to various aqueous systems during the production process.
• Packaging Specification: 50 kg/drum. High - quality packaging drums are used, which have good sealing, corrosion resistance and impact resistance. They can effectively protect the product from external factors during transportation and storage, preventing volatilization, leakage or deterioration.
• Physical Parameters:
  • Density: Approximately 1.0 - 1.1 g/cm³ (at 25℃), similar to the density of common aqueous systems. This helps it to be uniformly dispersed in aqueous systems and fully exert its rheological regulation function.
  • pH Value: Generally between 6 - 8 (1% aqueous solution), nearly neutral. It will not significantly affect the acid - base property of aqueous systems, reducing interference with system stability.
  • Viscosity: 400 - 1000 mPa·s (at 25℃). This viscosity range facilitates product storage and transportation, and also helps it to be quickly mixed uniformly with other materials during production.

2. Product Features

• Excellent Anti - Sagging Property: In applications such as water - based industrial coatings, water - based wood coatings and water - based metal coatings, it can significantly increase the viscosity of the system. Especially after the disappearance of high shear forces (such as spraying and brushing), it quickly recovers viscosity, effectively preventing the coating from flowing on vertical surfaces. This makes the coating thickness uniform, avoids sagging, and ensures the appearance quality and protective performance of the coating.
• Outstanding Anti - Settling Property: For aqueous systems containing solid particles such as pigments and fillers (such as wood product coatings and water - based sealants), it can adjust the rheological properties, make the solid particles uniformly dispersed in the system, and reduce the settlement of particles. This extends the storage stability of the product and avoids quality problems caused by precipitation, such as uneven color and reduced coating performance.
• Good Leveling Property: It endows aqueous systems with good fluidity. After the application of coatings or sealants, they can automatically spread to form a smooth surface, fill small unevenness, reduce surface defects, and improve the decoration and functionality of products.
• Wide System Applicability: It is suitable for a variety of aqueous systems, whether colored water - based industrial coatings (used for protecting and decorating workpieces), transparent water - based wood coatings (highlighting wood texture while providing protection), water - based metal coatings (preventing metal corrosion), wood product coatings or water - based sealants. It can well exert the rheological regulation effect and meet the needs of different industries and products.
• Good Compatibility with Systems: It has good compatibility with various additives (such as dispersants, defoamers, bactericides, etc.) as well as resins and pigments in aqueous systems. No chemical reactions or adverse phenomena such as flocculation and turbidity will occur, ensuring the stability and performance of the entire formulation system.

3. Application Fields

• Water - Based Industrial Coatings Field: In industrial production such as automobile parts coating and mechanical equipment coating, RHEOLATE 299 can help water - based industrial coatings maintain a good atomization effect during spraying. After application, it quickly prevents sagging, forming a uniform, flat coating with good protective performance, effectively resisting the erosion of the external environment on metal and other substrates.
• Industrial Water - Based Wood Coatings Field: Used in the coating of furniture, floors and other wood products, it can make wood coatings level better, show the natural texture of wood, and prevent the coating from flowing on vertical wooden surfaces. This improves coating efficiency and quality, endowing wood products with beautiful appearance as well as good wear resistance and scratch resistance.
• Industrial Water - Based Metal Coatings Field: In metal protective coating, such as steel structure anti - corrosion and metal door and window coating, this rheology additive can effectively prevent pigment precipitation, ensure that metal coatings are uniformly covered during application, form a continuous and dense protective film, enhance the corrosion resistance of metals, and prolong the service life of metals.
• Wood Products Field: For the surface coating of wood products such as cabinets and wardrobes, RHEOLATE 299 can ensure that pigments and fillers in the coating are uniformly dispersed, avoid precipitation during storage. At the same time, it provides good leveling and anti - sagging properties during the coating process, making the coating on the surface of wood products more beautiful and durable.
• Water - Based Sealants Field: In application scenarios such as building sealing and automobile sealing, it can adjust the viscosity and rheological properties of water - based sealants. This makes them have good fluidity during extrusion application, easy to operate. After application, they can quickly set and prevent flowing, ensuring the sealing effect and improving the applicability and reliability of sealants.

4. Usage Methods & Recommended Dosage

• Recommended Dosage: Generally 0.2% - 1.0% based on the total formula mass. The specific dosage needs to be adjusted according to factors such as the type of aqueous system, viscosity requirements, application process and performance requirements of the final product. For example, the dosage for industrial water - based metal coatings with high requirements for anti - settling and anti - sagging properties may be close to 1.0%, while the dosage for some transparent water - based wood coatings with relatively low viscosity requirements may be between 0.2% - 0.5%. It is recommended to determine the optimal dosage through small - scale formula tests.
• Addition Methods:
  • Direct Addition Method: When the aqueous system is in a stirring state, slowly and evenly add RHEOLATE 299 into the system, and continue stirring for 15 - 30 minutes to ensure that the rheology additive is fully dispersed and interacts with other components in the system, achieving the ideal rheological regulation effect. This method is suitable for most aqueous systems.
  • Pre - dilution Method: If the viscosity of the aqueous system is high or more precise control of the dosage is required, the rheology additive can first be pre - diluted with deionized water or other suitable aqueous solvents in the system (the dilution ratio is generally 1:5 - 1:10), and then added to the system with continuous uniform stirring. Pre - dilution can improve the dispersion efficiency of the rheology additive in high - viscosity systems and avoid the phenomenon of uneven local thickening.

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 not used up at one time, the packaging drum should be sealed promptly to prevent the product from absorbing moisture, volatilizing or reacting with substances in the air, which may affect its performance.
• Safety Precautions:
  • Operators should wear appropriate protective equipment such as gloves and goggles when using this rheology additive to avoid skin and eye contact. If it accidentally comes into contact with the skin, rinse immediately with plenty of water; if it splashes into the eyes, rinse immediately with plenty of water and seek medical attention promptly.
  • Although this product is not flammable or explosive, the storage and use areas should still maintain good ventilation to avoid the accumulation of a large amount of vapor. At the same time, it should be avoided to store or transport it together with strong oxidants, strong acids and strong alkalis to prevent chemical reactions. During handling, handle with care to avoid damage to the packaging drum due to impact or extrusion, which may lead to product leakage.
