Oil-soluble polyurethane foam waterstop agent (grouting liquid)

Product Overview
The oil-soluble polyurethane foam waterstop agent is composed of polymeric MDI, a high-molecular chemical grouting and leak-stopping material generated through polymerization chemical reactions between polyisocyanate and polyol polyether. It has immediate leak-stopping effects on concrete structures or foundation reinforcement, and emergency water sealing.

Packaging, Storage, and Transportation

Special iron drums, 20KG (10KG) drums. Normally stored in a dry and cool place, avoiding direct sunlight, rain, inversion, and heavy pressure.

product features

◎ It has good hydrophobicity, and after grouting, it undergoes immediate polymerization and foaming expansion, solidifying with sand, stone, and soil into a rigid solidified body, quickly blocking cracks and sealing water.

◎ The solidification time can be controlled, and the foaming time of the product after encountering water can be adjusted from tens of seconds to hundreds of seconds.

◎ It is highly expansive, non-shrinking, and exhibits strong adhesion to the base layer. Furthermore, it maintains high strength after foaming and curing.

◎ It has good groutability, allowing for grouting even at low temperatures. Single-fluid grouting makes construction simple and cleaning easy.

◎ We can customize and produce oil-soluble polyurethane leak stoppers for subway and coal mine emergency use according to customer needs.
