RHEOBYK-420 Liquid rheology additive for aqueous and water-reducible coating systems
DESCRIPTION
Anjeka 4420 is a liquid rheological additive suitable for water-borne coatings and adhesives. The additive produces highly thixotropic fluidity to improve sag resistance and settling resistance. The additive can be added later.
PRODUCT DATA
Composition : Solution of modified polyurea
Typical Properties
The values given in this data sheet describe the typical properties and do not constitute specification limits.
Density: 1.1 g/ml (25℃)
Viscosity: 300-1600 cps (25℃)
Non-volatile matter (20 min., 150 ℃): 50%
Solvents: N-Methylpyrrolidone
STOREGE AND TRANSPORTATION
Temperature sensitive. Store in dry condition. Slight turbidity of the material that occurs during the storage has no influence on the rheological effectiveness.
Incorporate the additive into the coating system using moderate shear to ensure even and quick dispersion. Once integrated, the additive creates a three-dimensional network structure, providing thixotropic flow characteristics. This prevents particle sedimentation and improves anti-sagging properties without affecting leveling.
Use 0.2-1% of the additive (as supplied) based on the total formulation to prevent settling.
Use 0.5-2% to prevent sagging, depending on the solids content in the formulation.
Architectural Coatings: Improved application properties, smooth finish, and sag resistance.
Industrial Coatings: Enhanced durability, stability, and performance under varying environmental conditions.
Automotive Coatings: High-quality finish, good leveling, and consistent film thickness.
Wood Coatings: Better flow, leveling, and penetration into wood substrates.
Improved Application Properties: Ensure smooth and uniform application without defects like brush marks or sags.
Enhanced Stability: Prevent settling of pigments and fillers, maintaining uniformity in the coating.
Controlled Viscosity: Provide the desired viscosity for different application methods (brushing, rolling, spraying).
Thixotropy: Allow easy application under shear and quick recovery to prevent dripping and sagging.
Processing Instructions
Add the additive while stirring to ensure even distribution. Temperature control is not necessary. The additive can also be used to adjust viscosity later in the process by incorporating it as a post-additive.
