BD-3245

Silicone Wetting Agent, Silicone Surfactant, Plastic Coating Wetting Agent

This product is a low-viscosity, low-surface-tension silicone polymer. It imparts excellent spreading, wetting, and penetration properties, making it a new type of high-efficiency silicone additive.

Provides good spreadability and wettability on difficult-to-treat substrates, such as high-gloss packaging materials like polyethylene, polypropylene, and polyester. Suitable for inks, decorative and industrial coatings for plastics, metals, and wood. Used as a wetting and leveling agent in water-based, UV-curable, conventional solvent-based, and high-solids coatings, with recoatability and gloss retention features. This product is widely used in water-based PU coatings.

Typical Applications

• Industrial coatings
• Wood paints
• Water-based coatings
• Plastic coatings
• Transportation coatings

Application Recommendations

• Recommended dosage: 0.1-1.0% based on total formulation

• Addition method: Can be added during grinding or stirring, or post-added after production. For ease of addition, pre-dilute with a suitable solvent.

• Solvent types: Water, alcohols, alkanes, aromatics can be diluted in any ratio.

• Applicable coating systems:

Precautions

May have foam-stabilizing effect in water-based systems. Alternatively, select BD-3281 with better foam-suppressing performance.

Taboos

Use with caution when mixing with other additives. Below freezing point, it may form emulsions; it recovers upon warming. For applications requiring precision, re-test applicability.
