1. Basic Information

• Brand & Model: DeuRheo WT - 105A
• Core Ingredient: Non - ionic polyurethane associative thickener, a high - molecular polymer with a special structure. It regulates rheological properties through intermolecular association and interaction with other components in the system. Its non - ionic nature enables it to function stably in aqueous systems with different acid - base properties.
• Appearance & Character: Typically a colorless to light yellow transparent or translucent liquid with moderate fluidity and no obvious mechanical impurities, facilitating addition and mixing in various production processes.
• Packaging Specification: 25 kg/drum. High - quality packaging drums are used, featuring excellent sealing and corrosion resistance. They can effectively prevent the product from external contamination, volatilization, or chemical reactions with other substances during transportation and storage, ensuring stable product quality.
• Physical Parameters:
  • Density: Approximately 1.0 - 1.1 g/cm³ (at 25℃), similar to the density of common aqueous systems, which is beneficial for uniform dispersion in the system.
  • pH Value: Generally between 6 - 8 (1% aqueous solution), nearly neutral. It does not significantly affect the acid - base balance of aqueous systems, minimizing interference with system stability.
  • Viscosity: 500 - 1500 mPa·s (at 25℃). This viscosity range not only facilitates product storage and transportation but also allows for rapid mixing with other materials through stirring during production.

2. Product Features

• Broad System Applicability: It has good adaptability to various aqueous systems, including water - based coatings, latex paints, water - based adhesives, textile coatings, leather coatings, and water - based inks. Whether it is low - viscosity water - based inks or leather coatings requiring high viscosity, it can effectively adjust their rheological properties to meet the needs of different industries and products.
• Excellent Thickening Effect: It can significantly increase the viscosity of aqueous systems, and the viscosity range of the system can be flexibly adjusted according to the amount added. In water - based coatings, an appropriate viscosity can prevent sedimentation during storage and avoid sagging during application (such as spraying, brushing, and rolling), resulting in a more uniform and smooth coating.
• Superior Rheological Control: It endows the system with excellent pseudoplastic rheological properties. When subjected to shear forces (such as mechanical forces during stirring and spraying), the system viscosity decreases rapidly, enhancing fluidity for easy application. When the shear force disappears, the viscosity quickly recovers, preventing coatings or inks from flowing on vertical surfaces and ensuring coating or printing effects.
• Stable Storage Performance: It can improve the storage stability of aqueous systems, reducing quality instability caused by issues such as particle sedimentation and delamination in the system. During long - term storage, it maintains the uniformity and consistency of the system, extending the product shelf life.
• Outstanding Compatibility: It has good compatibility with various additives (such as dispersants, defoamers, fungicides) in aqueous systems, as well as pigments and fillers. No chemical reactions or adverse phenomena such as flocculation and turbidity occur, ensuring the stability and performance of the entire formulation system.

3. Application Fields

• Water - Based Coatings Field: In architectural water - based coatings (such as exterior wall latex paints and interior wall latex paints), it adjusts viscosity and rheological properties to ensure good leveling and anti - sagging performance during coating application, guaranteeing the appearance and quality of the coating. In industrial water - based anti - corrosion coatings, it helps with the uniform dispersion of pigments and fillers, enhancing the adhesion and protective performance of the coating.
• Latex Paint Field: It improves the thixotropy of latex paints, making them easier to apply during brushing or rolling without dripping. At the same time, it forms a uniform and smooth film during the drying and film - forming process, enhancing the decorative effect.
• Water - Based Adhesives Field: It improves the viscosity and fluidity of water - based adhesives, making them more uniform during coating and enhancing wettability and bonding strength on different substrates (such as paper, wood, and plastic). It is widely used in packaging, paper processing, wood processing, and other industries.
• Textile Coatings Field: Used in fabric printing, coating finishing, and other processes, it controls the rheology of coatings on the fabric surface, ensuring clear and accurate printed patterns, as well as the uniformity and firmness of the coating, improving the appearance and functionality (such as water resistance and stain resistance) of textiles.
• Leather Coatings Field: During leather finishing, it helps coatings adhere better to the leather surface, forming a uniform and wear - resistant coating. At the same time, it endows leather with a good hand feel and appearance, meeting the production needs of different leather products (such as leather shoes, leather bags, and leather clothing).
• Water - Based Inks Field: It adjusts the viscosity and rheological properties of water - based inks, enabling them to transfer uniformly to printing substrates during printing, ensuring the clarity of printed patterns and the vividness of colors. It is suitable for various printing processes such as paper printing and plastic film printing.

4. Usage Methods & Recommended Dosage

• Recommended Dosage: Generally 0.1% - 1.0% based on the total formula mass. The specific dosage needs to be adjusted according to factors such as the type of system, viscosity requirements, and application process. For example, the dosage for leather coatings requiring high viscosity and strong anti - sagging performance may be close to 1.0%, while for some water - based inks requiring low viscosity, the dosage may be between 0.1% - 0.3%. It is recommended to determine the optimal dosage through small - scale formula tests.
• Addition Methods:
  • Direct Addition Method: Under the stirring state of the aqueous system, slowly and evenly add DeuRheo WT - 105A to the system, and continue stirring for 15 - 30 minutes to ensure the rheology additive is fully dispersed and interacts with other components in the system, achieving the ideal rheological adjustment effect. This method is applicable to most cases.
  • Pre - dilution Method: If the system viscosity is high or more precise control of the dosage is desired, 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 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.
