water-based thixotropic agent equivalent to BYK420 Enhanced Penetration into Glass Fiber Boards

Anjeka 4420 Liquid Thixotropic agent water Enhanced Penetration into Glass Fiber Boards

General 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

Chemical 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.

Application

Incorporate the additive into the coating system using moderate shear to achieve uniform and rapid dispersion. Once integrated, the additive forms a three-dimensional network structure, imparting thixotropic flow characteristics. This helps prevent particle sedimentation and enhances anti-sagging properties without compromising leveling.

Recommended Addition Level

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.

Applications in Coatings:

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.

Benefits of Liquid Rheological Agents:

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.
