Get the advantages of silicones for challenging sealant applications

With silicone pavement sealants from Dow, you can count on the features of high-performance silicone materials, including:

• Long-term elasticity and high movement capability that accommodates thermal and loading movement
  
• Long-term integrity and adhesion that keeps water and incompressible debris out of joints – maintaining their functionality, avoiding cracks and preventing freeze-thaw damage
  
• Weather resistance – silicone sealants are virtually unaffected by long-term ultraviolet light, rain, snow, ozone, de-icing chemicals and temperature extremes
  
• Outstanding movement capability (+100/-50 percent) without splitting, cracking or losing adhesion
  
• Quick installation so newly sealed areas can be opened to traffic within an hour
  
• Low to ultra-low modulus
  
• Ability to seal irregular joint widths

Silicone pavement sealants are available in one- and two-part formulations, including self-leveling and non-sag formulations.
