BD-3467

Silicone Leveling Agent, Polyurethane Coating Leveling Agent, Polyurethane Uniform Foaming Agent

This product is a reactive leveling agent. It can graft onto polyurethane resin through reaction of its hydroxyl groups with isocyanate (-NCO), achieving long-lasting effects. In addition to excellent leveling, anti-craters, and substrate wetting properties, it also features anti-blocking and release aid, smooth feel, improved scratch and wear resistance, low-temperature flexibility, and enhanced breathability and moisture permeability.

This product is suitable for comprehensive modification of polyurethane coatings, PU leather, and similar composite coatings.

Typical Applications

• Polyurethane Coatings/Foaming Systems

Application Recommendations

• Recommended Dosage: 0.05-1% based on total formulation for solvent-based systems, 0.5-5% based on resin solids for resin modification, 0.5-5% based on total formulation for water-based systems

• Addition Method: For polyurethane modification, add together with polyols during prepolymerization or later stage. For coating modification, add directly; for ease of addition, dilute with suitable solvent first.

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

• Applicable Coating Systems:

  Coating System	Applicable
  UV System	√
  Solvent System	√
  Water-based System	√

Precautions

This product prioritizes system compatibility, so feel expression is slightly insufficient. If special emphasis on feel is needed, try BD-3253 as alternative.
