Waterproof and sealing material
Rescue polyurethane grout
Rescue polyurethane grout
The rescue type polyurethane grouting material DDPU-301 is a rescue type two-component hydrophobic polyurethane grouting material. The material immediately reacts with water, and the volume rapidly expands to form a water-insoluble foam, which can not only be waterproof. Leakage, there is a certain reinforcement and reinforcement effect.
一、characteristic
1. Fast curing, rapid reaction, foaming and solidification after water contact, the reaction time can be adjusted according to the amount of component A, generally can be controlled within tens of seconds to tens of minutes;
2, good hydrophobic properties, high chemical stability;
