Acrysol K-140

Acrysol K-140 is a highly efficient associative thickener designed for use in a wide range of waterborne formulations. It is particularly well-suited for applications in coatings, adhesives, and other industrial products requiring precise viscosity control and excellent stability.

Chemical Composition

Acrysol K-140 is an anionic, hydrophobically modified alkali-soluble emulsion (HASE) polymer. This unique composition enables it to deliver outstanding performance across various parameters, making it a preferred choice for formulators seeking superior thickening properties.

Key Features

  1. Excellent Thickening Efficiency: Acrysol K-140 provides exceptional thickening efficiency, allowing for the use of lower concentrations to achieve desired viscosity levels. This translates to cost savings and enhanced performance in end-use applications.

  2. Broad pH Range Stability: One of the standout features of Acrysol K-140 is its stability across a wide pH range (3-12). This makes it versatile and compatible with a diverse array of formulations.

  3. Outstanding Rheology Control: The product imparts excellent rheological properties, ensuring smooth application, good flow, and leveling characteristics. It also helps in preventing sagging and settling, which is crucial for high-quality finishes.

  4. Enhanced Film Formation: Acrysol K-140 aids in forming durable and resilient films, improving the mechanical properties and longevity of the final product. It is particularly beneficial in coatings where film integrity is critical.

  5. Compatibility: This thickener is compatible with a wide variety of pigments, fillers, and other additives, making it a flexible choice for formulators. It integrates seamlessly into both new and existing formulations.

Applications

  • Architectural and Industrial Coatings: Acrysol K-140 is extensively used in both architectural and industrial coatings, providing superior viscosity control and enhancing the overall performance of the coating.

  • Adhesives: The product is an excellent choice for formulating adhesives, where consistent viscosity and strong adhesion properties are essential.

  • Textile and Paper Coatings: In textile and paper industries, Acrysol K-140 offers enhanced printability and coating quality, ensuring vibrant colors and durable prints.

  • Personal Care Products: Its application extends to personal care products, where it acts as a thickening agent in lotions, creams, and other formulations, providing a desirable texture and feel.

Usage Instructions

Acrysol K-140 is typically added to the formulation at the beginning of the manufacturing process. It can be incorporated directly into the aqueous phase under high-speed stirring to ensure uniform dispersion. The optimal concentration will depend on the specific application and desired properties, generally ranging from 0.2% to 1.0% by weight.

Safety and Handling

  • Storage: Store Acrysol K-140 in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the container is tightly closed when not in use to prevent contamination.

  • Handling: Use appropriate personal protective equipment (PPE) such as gloves and eye protection when handling the product. Refer to the Safety Data Sheet (SDS) for detailed information on safety measures and first aid procedures.
