WILLPUR® WS-X

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.
