WILLPUR® WS-F
Extremely fast reacting, dual-component polyurethane resin with short reaction time
description
WILLPUR® WS-F 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. The low viscosity allows good penetration, allowing WILLPUR® WS-F to get into the tightest fissures, ensuring permanent consolidation.
