Anjeka7410 anti-blocking leveling agent excellent wetting and leveling for polyurethane adhesive BYK322

ANJEKA-7410 organosiloxane polymer with good alignment of matte powder and aluminum powder

GENERAL DESCRIPTION

Anjeka-7410 is a multifunctional aryl-modified silicone additive that combines leveling, flow enhancement, and defoaming properties. It moderately reduces the surface tension of coatings to improve film formation while preventing common defects such as Benard cells.

PRODUCT DATA

• Chemical Composition: Aryl-modified polymethylalkylsiloxane.

• Typical Physical & Chemical Data: (Values are typical and not binding specifications.)

  • Appearance: Colorless to pale yellow, transparent liquid.

  • Solubility: Oil-soluble.

  • Density (23°C): 0.85 – 1.05 g/cm³.

  • Viscosity (25°C): 300 – 3,000 mPa·s.

  • Active Ingredient: 100%.

STORAGE & HANDLING

• Store in a cool, ventilated area between 0°C and 40°C.

• Keep containers tightly sealed and away from heat and ignition sources.

• Avoid direct exposure to heat radiation.

• Recommended shelf life: 12 months.

SPECIAL NOTES

While Anjeka-7410 exhibits broad compatibility, it is advisable to conduct preliminary tests for long-term storage stability, recoatability, and crater resistance in specific formulations prior to full-scale use.

APPLICATION GUIDELINES

Features and Benefits
Anjeka-7410 is a versatile silicone additive that delivers leveling, limited defoaming (system-dependent), and surface enhancement without compromising key performance attributes.

Key Advantages:

• Thermal Stability: Withstands baking temperatures up to 250°C (480°F).

• Surface Enhancement: Increases slip and improves scratch/abrasion resistance.

• Defect Prevention: Effectively prevents Benard cell formation.

• Particle Orientation: Improves the alignment of aluminum flakes and matting agents.

• Process Stability: Stabilizes the curtain in curtain-coating applications.

• Formulation Flexibility: Does not adversely affect intercoat adhesion or increase gloss, making it suitable for challenging systems such as high-solids polyurethanes and acid-cured polyesters.

Recommended Application Sectors

• Solvent-borne industrial and wood coatings.

Recommended Dosage

• 0.1% – 0.5% on total formulation weight.

Note: This is a typical starting range. The optimum dosage should be determined through application testing.

Incorporation & Processing
Can be added at any stage of production, including as a post-additive.

PACKAGING
