Core Ingredient: Anionic acrylic polymer, a high - molecular compound polymerized from acrylic monomers. It regulates rheological properties through the interaction between anionic groups on its molecular chain and other components in aqueous systems.
Appearance & Character: Typically a colorless to light yellow transparent or translucent liquid with good fluidity, free from visible impurities to the naked eye. This makes it easy to mix and add with other materials during the production process.
Packaging Specification: 50 kg/drum. High - quality packaging drums that meet relevant standards are used, featuring excellent sealing and corrosion resistance. They effectively prevent product leakage, volatilization, and chemical reactions with external substances during transportation and storage, ensuring stable product quality.
Physical Parameters:
Density: Approximately 1.05 - 1.15 g/cm³ (at 25℃), similar to the density of common aqueous systems. This facilitates uniform dispersion in aqueous systems, allowing it to fully exert its rheological regulation effect.
pH Value: Generally between 7 - 9 (1% aqueous solution), showing weak alkalinity. This enables it to maintain stable performance in most aqueous systems.
Viscosity: 300 - 800 mPa·s (at 25℃). The moderate viscosity makes it convenient for storage, transportation, and mixing with other materials through stirring during production.
2. Product Features
Excellent Rheological Regulation Ability: It can effectively enhance the medium - shear viscosity thixotropy of aqueous systems. When subjected to medium shear forces (such as mechanical forces during spraying and brushing), the viscosity of the system changes significantly, making coatings or inks easier to apply and avoiding sagging. When the shear force disappears, it can quickly recover a certain viscosity to maintain good shape stability, ensuring uniform and consistent coating or printing results.
Good Flowability and Leveling Property: It endows aqueous systems with good flowability, enabling materials to be smoothly transported and stirred in production equipment. After application, it also provides good leveling property, allowing the material to spread automatically to form a smooth and flat surface, reducing surface defects and improving the appearance quality of products.
Superior Water Retention and Compatibility: It has excellent water retention capacity, which can prevent the rapid evaporation of water in aqueous systems. This is particularly effective in maintaining system stability in high - temperature environments or during long - term storage. Meanwhile, it has good compatibility with various pigments, fillers, and additives in aqueous systems, without causing adverse phenomena such as flocculation and sedimentation. This facilitates color mixing operations and meets the diverse needs of customers for product colors and properties.
Special Adaptability to Alkaline Environments: In alkaline environments, it produces a relatively small thickening effect. This makes it suitable for some aqueous systems with special requirements for alkaline environments, avoiding excessive viscosity increase of the system due to changes in alkalinity that may affect its usability and increasing the flexibility of product application.
Environmental Friendliness and Stable Storage Performance: It contains no organic solvents or alkylphenol ethoxylates (APEO), complying with environmental protection requirements and meeting the current market demand for green and environmentally friendly products. Additionally, it has excellent storage stability. Under normal storage conditions, the performance of the product does not change significantly over time, reducing the risk of product quality issues caused by storage problems and extending the shelf life of the product.
3. Application Fields
Water - Based Coatings Field: In architectural water - based coatings (such as exterior wall latex paints and interior wall latex paints), by regulating rheological properties, it enables the coating to better adhere to the wall surface, form a uniform and flat coating, and improve the decorative effect and protective performance. In industrial water - based anti - corrosion coatings, it helps with the dispersion of pigments and fillers, enhances the adhesion and anti - corrosion performance of the coating, and protects metal and other substrates from corrosion.
Latex Paint Field: It improves the thixotropy and leveling property of latex paints, making them smoother during brushing or rolling, less prone to sagging and brush marks. After drying, a smooth and flat paint film is formed, enhancing the decorative effect and user experience.
Textile Coatings Field: Used in fabric printing, coating finishing, and other processes, it can control the rheology of coatings on the fabric surface, ensuring clear and accurate printed patterns as well as uniform and firm coatings. It endows textiles with good hand feel and functionality (such as water resistance, stain resistance, and wear resistance).
Water - Based Adhesives Field: In the production and use of water - based pressure - sensitive adhesives, water - based white latex, water - based polyurethane adhesives, etc., it regulates the viscosity and flowability of the adhesive. This enables the adhesive to better wet the surface of the adherend, improve the bonding strength and bonding effect, and it is widely used in packaging, paper processing, wood processing, and other industries.
Water - Based Screen Printing Inks Field: It optimizes the rheological properties of water - based screen printing inks, allowing them to be evenly transferred through the screen to the printing substrate during the screen printing process. This ensures the clarity of printed patterns, the vividness of colors, and the neatness of edges, making it suitable for screen printing processes on various printing substrates such as paper, plastic films, and fabrics.
4. Usage Methods & Recommended Dosage
Recommended Dosage: Generally 0.2% - 1.5% based on the total mass of the formula. 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 coatings with high requirements for thixotropy may be close to 1.5%, while the dosage for some water - based screen printing inks 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: Under the stirring state of the aqueous system, slowly and evenly add DeuRheo WT - 115 to the system, and continue stirring for 15 - 30 minutes. This ensures that the rheology additive is fully dispersed and interacts with other components in the system, achieving the ideal rheological regulation effect. This method is easy to operate and 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.
