  • Provides permanently flexible watertight joints.
  • Low to high temperature workability: 0°F to 120°F (-12°C to +48°C)
  • Rugged service temperature: -30°F to +200°F (-34°C to +93°C)
  • Excellent chemical and mechanical adhesion to clean dry surfaces.
  • Greater cohesive and adhesive strengths.
  • Sealed joints will not shrink, harden or oxidize upon aging.
  • Controlled flow resistance for application ease.
