Anjeka4350 Aluminum powder directional agent Modified ethylene-vinyl acetate copolymer wax emulsion Slow down pigment sedimentation White emulsion BYK8421

PRODUCT OVERVIEW
Anjeka-4350 is a specially modified ethylene‑vinyl acetate (EVA) copolymer emulsion designed to enhance the orientation and stability of effect pigments (e.g., aluminum flakes, pearlescent pigments) in water‑based coatings.

TECHNICAL SPECIFICATIONS
Chemical Composition: Non‑ionic ethylene‑vinyl acetate copolymer emulsion.
Note: The values below are typical and should not be regarded as exact product specifications.

Appearance: Milky white emulsion
Diluent: Water
Density (23 °C): 1.00–1.05 g/cm³
Active Content: 20 %
pH (as supplied): 3–5

STORAGE & HANDLING
Store in sealed containers in a cool, well‑ventilated area away from heat and ignition sources. Recommended storage temperature range is 5 °C to 40 °C. Do not store beyond 12 months.

PERFORMANCE BENEFITS
Anjeka-4350 significantly improves the alignment of metallic and pearlescent pigments, resulting in a stronger flop effect (color‑shift with viewing angle) and reduced mottling or flooding. It also helps retard pigment settling in the can, extending in‑can stability.

RECOMMENDED APPLICATIONS
Ideal for water‑borne metallic basecoats, effect‑pigment primers, and single‑coat metallic topcoats.

DOSAGE GUIDANCE
Typical addition level: 5–10 % on total formulation weight (as supplied).
Note: This range is a starting point; optimal dosage should be confirmed through formulation‑specific trials.

PROCESSING INSTRUCTIONS

pH adjustment: Before addition, adjust the system pH to 8.5–9.5 for best compatibility.

Addition: Introduce Anjeka-4350 after the effect pigments have been incorporated, using low‑ to moderate‑shear mixing.

Dilution: No pre‑dilution with water is required.
