Sikaflex®-423 PowerCure

Accelerated polyurethane sealant for floor joints and civil engineering applications

Sikaflex®-423 PowerCure is a 1-part, accelerated, elastic polyurethane sealant. It seals many kinds of joint configurations in floors and civil engineering structures. The elasticity is maintained over a wide temperature range and high mechanical and chemical resistance provides good durability.

  • High movement capability: ±25 % (ISO 9047).
  • Fast development of mechanical properties.
  • Very good mechanical resistance.
  • Very good resistance to specific chemicals.
  • High resistance to weathering.
  • Good durability.
  • Non-staining to a wide range of substrates.
  • Monomeric diisocyanate content <0.1 %: no user safety training needed (REACH restriction 2023, Annex XVII entry 74).
  • Bubble-free curing.
  • Good adhesion to many construction materials.
