[Asia Economy Reporter Kim Jong-hwa] Samhwa Paint Industrial Co., Ltd. announced on the 17th that it has developed 'I Saenggak Super Care Exterior Grade 1.'

'I Saenggak Super Care Exterior Grade 1' is a high-performance paint that meets the KS standard for exterior Grade 1 water-based paint, seals micro-cracks on building exterior surfaces, and extends the lifespan of buildings with excellent water repellency and tensile strength.

Concrete, which forms the framework of buildings, is strongly alkaline. However, over time, carbonation occurs due to exposure to carbon dioxide in the air and acid rain, causing the concrete to lose its alkaline properties. Concrete carbonation leads to crack formation and corrosion of reinforcing steel due to moisture and carbon dioxide penetration, which is the main cause of building deterioration.

Therefore, waterproof finishing on building exteriors is important, but existing water-based paints for exterior use had limitations in these functions.

'I Saenggak Super Care Exterior Grade 1,' developed by Samhwa Paint, effectively prevents concrete carbonation by satisfying the physical properties of protective coatings for concrete, such as chloride penetration resistance, impermeability, and carbonation resistance. In addition, it prevents fine cracks on exterior walls with excellent elongation and has superior water repellency to block moisture penetration caused by rainwater.

A representative from Samhwa Paint stated, "Applying I Saenggak Super Care will significantly reduce the cost and time spent on building maintenance, thereby extending the economic lifespan of buildings," adding, "Since the concrete durability design standards were revised in 2021, inquiries from construction companies about concrete carbonation prevention coatings have been steadily increasing, so demand is expected."
