Product Overview
AgeSin® LA-D5431 is a high-performance polyether-modified silicone leveling agent designed to eliminate “pinholing” defects in two-component systems under humid conditions. With low foam stability and excellent intercoat adhesion, it serves as an ideal BYK-331 alternative for solvent-based, water-based, and UV-curable coatings.

Technical Specifications
| Property | Value/Description |
|---|---|
| Composition | Polyether-modified polysiloxane copolymer |
| Appearance | Colorless to light yellow transparent liquid |
| Active Content | 100% |
| Solvent | None |
| Viscosity (25℃) | 100–1500 mPa·s (rotational viscometer) |

Applications
- Solvent-Based Coatings: Automotive refinish, industrial anti-corrosion coatings
- Water-Based Systems: Wood coatings, architectural paints
- UV-Curable Systems: Electronic device coatings, 3D printing resins
Key Benefits
- Low Foam Stability: Prevents “pinholing” in high-humidity environments, ensuring flawless film appearance.
- Superior Recoatability: Minimal impact on interlayer adhesion at optimized dosage (0.1–0.5%) and baking temperatures (80–120℃).
- Surface Performance:
- Moderately reduces surface tension for enhanced substrate wetting.
- Improves scratch resistance by 30% (ASTM D4060) with a smooth finish.
- Broad Compatibility: Compatible with epoxy, polyurethane, acrylic, and hybrid resin systems.
Competitive Edge vs. BYK-331
| Parameter | AgeSin® LA-D5431 | BYK-331 |
|---|---|---|
| Foam Stability | Excellent (no pinholing) | Moderate (foaming risks) |
| Recoat Adhesion | 5/5 (no impact) | 4/5 (slight impact) |
| Cost Efficiency | 10–15% lower dosage | Standard dosage |
Usage Guidelines
- Recommended Dosage: 0.1–0.5% (on total formulation)
- Mixing: Add during grinding phase for homogeneous dispersion.
- Storage: Store in dark, dry conditions (15–25℃); shelf life 24 months.
