Soil stabilizing hardener

This inorganic soil stabilizer is suitable for use with all types of soil. Its excellent binding properties firmly stabilize the ground, making it ideal for a wide range of applications, including temporary roads and work yards. Furthermore, the product meets the standards for 29 harmful substances based on soil environmental guidelines, ensuring it is designed with safety in mind.

Concrete deterioration inhibitor

This is a deterioration inhibitor designed to enhance the durability of concrete structures and slow the progression of deterioration. It effectively combats major causes of deterioration—such as salt damage, carbonation, and freeze-thaw damage—and reduces the risk of rebar corrosion. Unlike conventional surface protectants, it penetrates deep into the concrete while imparting water-repellent properties, thereby providing long-term protection for the structure.

Heat-shielding material

Next-generation heat-reflective coatings for roofs and exterior walls that utilize ultra-fine, amorphous silica, as well as heat-reflective window coatings that significantly block UV rays from entering through window glass, thereby improving indoor environments These solutions help reduce the load on air conditioning systems, contributing to energy savings and lower electricity bills

Cleaning agent

We offer a wide range of cleaning agents suitable for various applications, including water stains and dust on exterior walls, floors, and concrete structures, as well as grease stains on equipment and machinery. These products enhance the adhesion of coatings and significantly contribute to improving the quality of the finished work.

Coating material

This coating product is applied to areas vulnerable to rainwater, UV rays, salt damage, and chemicals to inhibit corrosion and the growth of mold and bacteria. It helps extend the service life of equipment and buildings.
