WILLPUR® WS FA

Extremely fast reacting, dual-component polyurethane resin with short reaction time

 

description

WILLPUR® WS-FA is a hard-elastic polyurethane resin. It cures to a dimensionally stable injection material suitable for stopping water inflows or consolidating soil and loose rock. Its low viscosity allows good penetration, allowing WILLPUR® WS-FA to get into the tightest fissures, ensuring permanent consolidation. Although it is not a high foaming product, in contact with water or even just moisture, it fills smaller fissures and cracks, with the effect of secure sealing even against higher water pressure.
