AI Technical Summary

Technical Problem

Coating agents for concrete surfaces can cause a 'wet skin' appearance, reducing visibility and making it difficult to detect cracks, while transparent coatings hinder uniformity confirmation and unevenness detection.

Method used

A coating composition comprising a non-radical reactive aqueous emulsion, colloidal silica, a radical generator, and a radical reactive dye, which allows for visible inspection during application and prevents wet skin, ensuring excellent adhesion and durability.

Benefits of technology

The composition enables easy visual confirmation of coating uniformity and prevents wet skin, maintaining substrate visibility and enhancing crack detection, with improved adhesion and reduced chloride ion permeability.
