CS-440 Fuel & Oil Resistant Sealant

For above and below ground fuel containment structures. Not intended for use in expansion joints or joints that move.

Technical Data

SEALING PROPERTIES

  • Provides permanently flexible watertight joints.
  • Excellent adhesion and structural integrity.
  • Bonds well to most surfaces, including: Concrete, Fiberglass, Metal, Plastic and aluminum.
  • Sealed joints will not shrink, harden or oxidize upon aging.
  • Controlled flow resistance for application ease.
  • Low to high temperature workability: 20°F to 120°F (-7°C to 48°C)
  • Rugged service temperature: -30°F to +200°F (-34°C to +93°C)
  • No priming normally necessary. When confronted with difficult installation conditions, such as wet concrete or temperatures below 40°F (4°C), priming the concrete will improve the bonding action. Consult Concrete Sealants for the proper primer to meet your application.
