Dow DOWSIL 29 Additive Leveling Agent

Dow DOWSIL 29 Additive Leveling Agent is a silicone-based surface modifier designed for high-performance coatings and inks. It enhances flow, reduces orange peel, and improves substrate wetting without affecting recoatability or gloss. Compatible with solventborne, waterborne, and UV-curable systems, it delivers consistent leveling at low dosages (0.05–0.3 wt%). Trusted for reliability in automotive, industrial, and graphic arts applications.

Features Of Dow DOWSIL 29 Additive Leveling Agent

  1. Enhances surface leveling and flow in silicone-based coatings and sealants.

  2. Reduces orange peel, craters, and other surface defects during cure.

  3. Compatible with addition-cure (Pt-catalyzed) and condensation-cure silicone systems.

  4. Maintains thermal and UV stability of the final cured formulation.

  5. Low-volatility liquid additive with minimal impact on pot life or viscosity.

Typical Applications Of Dow DOWSIL 29 Additive Leveling Agent

  1. High-gloss silicone architectural coatings for façades and cladding.

  2. Optical-grade encapsulants for LED and sensor protection.

  3. Automotive interior trim sealants requiring defect-free appearance.

  4. Electronics conformal coatings where uniform film thickness is critical.
