Rheology Additive 44
Overview
Rheological Additive 44 is a high-performance chemical additive designed to modify the rheological properties of various materials. It is widely used in industries such as coatings, adhesives, and construction to control viscosity, prevent sagging, and improve application performance. This additive is particularly valued for its ability to provide thixotropic behavior, meaning it reduces viscosity under shear stress (e.g., during mixing or application) but regains viscosity when at rest. This property is crucial for ensuring even application and preventing drips or runs in vertical surfaces.
Physical and Chemical Properties
Rheological Additive 44 typically appears as a white or off-white powder with a density ranging from 1.2 to 1.5 g/cm³. It exhibits partial solubility in water but disperses more effectively in organic solvents, making it suitable for a variety of formulations. Key chemical properties include its ability to form hydrogen bonds with other components in a mixture, which contributes to its thickening and stabilizing effects. The additive is stable under normal storage conditions but should be protected from excessive moisture to prevent clumping or reduced efficacy.
Main Applications
The primary use of Rheological Additive 44 is in the formulation of coatings, where it enhances viscosity and prevents sagging on vertical surfaces. It is also commonly added to adhesives and sealants to improve their workability and final performance. In construction materials, such as tile adhesives and grouts, this additive ensures proper consistency and reduces slump. Its versatility makes it a preferred choice for manufacturers seeking to optimize the rheological behavior of their products without compromising other properties like drying time or adhesion.
Safety and Storage
When handling Rheological Additive 44, it is essential to wear protective gloves and goggles to avoid skin contact or eye irritation. Inhalation of dust should be minimized by working in well-ventilated areas or using appropriate respiratory protection. Storage recommendations include keeping the additive in a cool, dry place, away from direct sunlight and moisture. Properly sealed containers are necessary to maintain the product's quality and prevent contamination. Bulk storage should be in areas with controlled humidity to avoid clumping.
B2B Procurement Guide
For B2B buyers, sourcing Rheological Additive 44 requires attention to compatibility with specific formulations. Request technical datasheets from suppliers to verify performance characteristics such as viscosity enhancement and thixotropic behavior. Price ranges typically fall between $5 and $15 per kilogram, depending on order volume and supplier terms. Consider testing small batches before large-scale procurement to ensure the additive meets your application requirements. Reliable suppliers often provide samples for evaluation.
