Founded in 1976, Samkang Hwasung Co., Ltd. is a specialized manufacturer of construction chemical materials.
In 1983, utilizing new technologies in line with advanced construction methods, the company became the first in Korea to independently develop and patent a concrete form release agent (Seracon), making a significant contribution to the advancement of the construction industry.
Driven by a commitment to the highest quality, Samkang Hwasung continuously engages in research and development to create and produce innovative products tailored to customer needs, supported by a nationwide distribution network.
Main Products
Form Release Agent Compatible with All Types of Molds
SERACON-500 (watery)
Manufactured using clean refined oil, this release agent is compatible with all types of formwork and provides excellent performance on large-surface or high-demand form conditions. In addition, it results in significantly fewer bug holes on the concrete surface compared to conventional release agents.
Liquid Membrane-Forming Curing Compound for Concrete
CUROM 2 TYPE (watery)
With excellent moisture retention, it maintains optimal curing conditions and prevents moisture evaporation even in harsh weather. It also helps prevent surface shrinkage such as cracks and fissures caused by water loss during concrete placement due to heat and radiant energy.
Oil- and Water-Based Release Agents for Tunnel and Precast Concrete
SERACON-GT3000
Its excellent release performance ensures a clean, smooth concrete surface, reducing defects and minimizing the cloud-like marks that often appear on the upper layer after demolding. It is easy to apply, spreads well, and provides strong adhesion to the surface of various lining forms.
Rust Converter / Remover
RUST CLEAR
It converts or removes rust and oxides from metal surfaces, passivating them in the process. After rust removal, it improves adhesion of protective coatings such as paint or anti-corrosion treatments. This water-based product offers excellent stability in removing rust and corrosion from steel rebar and pipe piles, while providing short-term rust protection.
100% Natural Bamboo Charcoal
HWAKSSEN
Eco-friendly natural bamboo charcoal made from 100% natural bamboo, safe for human use. This molded charcoal, made from natural bamboo charcoal, burns for an extended period, producing minimal odor and smoke while reducing carbon monoxide emissions. Its high heat output makes it especially suitable for use in concrete construction during cold weather.
