RepaCoat FX

Permanently Flexible Coatings


RepaCoat FX is a permanently elastic two-component polyurethane elastomer. It is a highly wear and abrasion resistant material that's ideal for use as a sealant, and for the repair of rubber. It allows economical, on-site application.

  • Flexible coating and repair tasks
  • Conveyors, rubber belts, rubber rollers
  • Gaskets
  • Expansion joints
  • Tubes, pumps, impellers, hoses
  • Tanks, silos
  • Pipes and elbows
  • Highly resistant to aggressive environments
  • Highly abrasion and tear resistant after cure
  • Provides full elastic recovery, even after multiple elongations and compression loading
  • Temperature resistant to 120°C (248°F) continuous; 160°C (320°F) peak
  • Fast curing (physical: 30 minutes; chemical, 72 hours)
  • Excellent adhesion on all metallic surfaces, natural and synthetic rubber, wood, concrete
  • .5 kg and 1 kg
  • Larger packages on request
  • Pot Life at 20°C: (68°F) approx. 10 minutes
  • Shelf Life: 12 months
