AI Technical Summary

Technical Problem

Existing waterproofing methods for underground and underwater structures are inadequate due to the lack of resistance to high pressure scratches and poor waterproofing properties, as they are not designed to withstand the unique conditions of soil environments and construction machinery impacts.

Method used

A waterproof coating composed of an acrylic resin emulsion, coloring and extender pigments, and water, with optional crosslinking agents, organic or inorganic particles, lubricants, and film-forming aids, forming a durable and resistant waterproof film that can be applied at room temperature and cures in one component, suitable for structures in or underwater.

Benefits of technology

The coating effectively prevents water ingress and maintains waterproof performance over time, even under high pressure and impact, extending the structural life and ensuring durability in challenging environments.
