Slow reacting two-component injection resin

CE marking according to EN 1504-5

Product description

WILLPUR® WS- X is a slow-setting 2-component injection resin, free from CFCs and halogens. It is used for sealing and consolidating in dry and water-bearing areas. Without water contact, the product cures very slowly to a high-strength, non-foamed polyurethane resin; when in contact with water, a faster reaction occurs, the product hardens to a compact, firm foam.

WILLPUR® WS- X is an injection resin with variable reaction time. Depending on the amount of catalyst added, the reaction time can be adapted to the needs on site.

Product details

  • is used to consolidate dry and water-bearing rock
  • seals water inflows from rock, soil or cracks in concrete and brickwork
  • is used for surface sealing (curtain injection)
  • closes cracks in the rock during tunnelling and prevents water flow along the tunnel axis
  • is used for force-locking injection in concrete and masonry
  • is used for the consolidation of soil under foundations and other monolithic building elements used
  • penetrates well into areas to be sealed
  • can be processed with 1-component injection pumps and 2-component injection pumps

Technical specifications

  • can be processed in one and two components
  • variably adjustable reaction time from 25 s up to 106 min. at 20°C and without contact with water
