"Extending Building Lifespan"... Samhwa Paint Obtains Patent for Concrete Carbonation Prevention Paint

Samwha Paint Industrial announced on the 6th that it has obtained a patent for a concrete neutralization prevention coating composition with enhanced weather resistance, elasticity, and waterproofing.

Concrete, mainly used in buildings, has strong alkalinity with a pH between 12 and 13.5, which protects the reinforcing steel inside the concrete and suppresses corrosion of the steel.

However, concrete gradually loses its alkalinity due to the effects of water and carbon dioxide in the atmosphere. This phenomenon is called concrete neutralization. When concrete neutralization occurs, cracks or delamination appear in the building, and in severe cases, the structure collapses.

Samwha Paint has newly developed a concrete neutralization prevention paint that protects buildings and ensures the safety of residents.

This paint is a high-performance product that extends the lifespan of buildings with enhanced weather resistance, elasticity, and waterproofing, helping to maintain the continuous safety and performance of concrete structures.

The paint meets the Korean Standard KS M 6010 (water-based paint) Type 1 Grade 1 specification.

In particular, this product referenced the KS F 4936 (coating materials for concrete protection) standard to test elasticity and waterproof performance under more severe environmental conditions. It also confirmed excellent concrete neutralization prevention effects through performance verification using KS F 2584 (accelerated carbonation test method for concrete).

A representative from Samwha Paint stated, “The concrete neutralization prevention paint is a long-lasting exterior finishing material that can reduce concrete strength maintenance costs, structural construction costs, and aging repair costs.”
