OPU polyurethane

OPU polyurethane
OPU is one component oil-soluble polyurethane grouting material it reacts with water and expand to be a foamm, which is a compund of MDI. It is a polymerization injection of polyisocyanate and Polyether Polyol. It has an immediate water stop effeccct on concrete and base strengthening for flood stoppage.

Features:
Fast foam speed
High foam rate
Good for gushing water, honeycomb structure, strengthening
Non shrink
Good for static seam

Product characteristic:
1.Good hydophobicity, immediate polymerization after injection, solidly mix togheter with gavel and mud.
2. Controllable solidification time. Reaction time can be controlled within couple of seconds to hundreds of second when injection meets water.
3. High expansion rate, no retraction, stront coherence with base, great intensity after solidificatiohn.
4. Easy injection, can be used under low temeratures, single fluid grouting, easy to use, easy to clean.
