Ultra-fast-curing, high-strength repair composition and construction method for structural repair and reinforcement using the same

Ultra-fast-curing, high-strength repair material combining coated nanofillers and fast-curing resin

This technology is an ultra-fast-curing, high-strength repair composition consisting of a base component containing polyurethane prepolymer, polymerizable compounds, polymerizable resin, UV stabilizers, dispersion stabilizers, and coated nanofillers, along with a curing agent component containing amine-based curing agents.

Conventional structural repair materials suffer from slow curing speeds, leading to long construction times, and poor nanofiller dispersion, which makes it difficult to achieve the necessary weather resistance and physical/chemical performance.

By uniformly dispersing nanofillers coated with silane compounds and utilizing a fast-curing, high-strength resin, this technology enables rapid curing and superior weather resistance when applied to structural repair and reinforcement projects.
