Polyurethane system, very fast reacting two-component injection resin


Product description

WILLPUR® HV is a Polyurethane (PU) foam. They are injection resins designed to expand by foaming with or without water, in this way they can be injected as a liquid that then foams and expands to fill voids and smaller cavities in rock-structures or loose ground. These materials have good adhesion to the rock and remain firm and rigid after the foaming process has finished. Therefore, these polyurethane foam resins are widely used for and stabilizing requirements in both Tunnels and mines.
