Pecora 300SL Self-Leveling Silicone Pavement Joint Sealant - 4.5 Gallon Pail

Pecora 300SL Silicone Pavement Sealant is a one-part, ultra low modulus elastomer designed for sealing joints in roadways. It has excellent unprimed adhesion to concrete, metal and asphalt substrates, superior weather resistance and remains flexible at extremely low temperatures. Pecora 300 SL Silicone Pavement Sealant is a self levelling product designed for applications on flat surfaces.

Basic uses:

Sealing of typical concrete, metal and asphalt roadway and airfield control joints.

Advantages

• Reduces pavement deterioration by restricting surface water penetration into underlying base and sub base layers
• Is a convenient one-component, neutral moisture curing system
• Ultra-low modulus resulting in high movement capability.
• Very easy to apply with standard automated bulk dispensing equipment such as Graco or Pyles
• VOC compliant
• Primerless adhesion to concrete and asphalt
• Aids in elimination of noncompressables entering expansion joints.

Limitations

Pecora 300 SL Silicone Pavement Sealant should not be used...

• for continuous water immersion conditions
• when ambient temperatures are below 40°F or above 120°F
• flush with traffic surface. (sealant should always be recessed below surface.)
• for applications requiring support of hydrostatic pressures
• with solvents for dilution purposes
• with concrete that is cured less than seven days
