"U Coat" is a coating-type surface scattering prevention material that enables high durability repairs through strong adhesion to repair surfaces, waterproofing, and weather resistance, all achieved with simple application. It does not use any organic solvents or other toxic substances, eliminating concerns about fire hazards during application, harm to workers' health, and air pollution. Additionally, due to its high solid content and quick drying time, the application time is significantly reduced. 【Features】 - A repair material for aggregate scattering prevention made primarily from asphalt, synthetic resins, and special fillers. - Allows for easy repairs, resolving aggregate scattering with just the application work. - Enables rapid application, with repairs of 5 to 20 m² completed in about 3 hours (during summer). *For more details, please download the PDF or feel free to contact us.

"Quick Bar" is a heating construction type pavement crack repair material made from high-viscosity special asphalt, which excels in adhesion and prevents the recurrence of cracks. It can be applied using a cassette burner, standard burner, or small to large trowels. Since it is primarily composed of asphalt and aggregates, there is no shrinkage after application. Additionally, its solid form and convenient size allow for waste-free usage. 【Features】 ■ Excellent adhesion due to the use of high-viscosity special asphalt ■ Thin sheet form that melts easily, providing excellent workability ■ Can be applied with a hand burner (torch burner) ■ Minimal shrinkage after application due to the primary use of asphalt and aggregates ■ Long-term storage is possible *For more details, please download the PDF or feel free to contact us.

The "thin layer" is an asphalt paving material suitable for filling in step differences (approximately 5mm and above) and for leveling rough pavement surfaces. Due to its property of hardening under pressure, it allows for immediate traffic opening after construction, and the natural compaction from passing vehicles increases its durability over time. 【Features】 ■ An environmentally friendly paving material that does not contain volatile organic solvents (VOCs) ■ Almost odorless, preventing irritating smells from filling warehouses or vehicles ■ No stickiness from solvents, making it less likely to soil hands, feet, or clothing ■ Can be stored for about 2 years without hardening after opening *For more details, please download the PDF or feel free to contact us.

"YK Pack" is a cold asphalt paving material that can be used for quick repairs of small potholes and cracks. It is packed directly into the repair area, and it hardens through natural compaction from the weight of passing vehicles, preventing the scattering of aggregate after traffic is reopened. Additionally, this product can be repaired in a short time, which has been recognized for its safety for workers, and it has a proven track record of use on highways. 【Features】 ■ Environmentally friendly paving material that does not contain volatile organic solvents (VOCs) ■ Almost odorless, preventing irritating smells from filling warehouses or vehicles ■ Can be stored for about 2 years as it does not harden after opening ■ Due to its property of hardening under pressure, it can be opened to traffic immediately after application *For more details, please download the PDF or feel free to contact us.

"PP Ascon" is a small-scale thin-layer overlay and drainage pavement material that uses high-viscosity asphalt, which produces strong bonding and durability. Not only is it suitable for repairing drainage pavements, but even for initial ruts, step corrections, and surface delamination, it can achieve strength early on when carefully compacted with a small compactor, allowing for long-term maintenance of the repaired areas. 【Features】 ■ By using high-viscosity asphalt, sufficient compaction allows for long-term maintenance of repaired areas compared to conventional products. ■ It has almost no odor, preventing irritating smells from filling warehouses or vehicles. ■ There is no stickiness from solvents, making it less likely to soil hands, feet, or clothing. ■ It does not harden after opening, allowing for approximately two years of storage. ■ Due to its property of hardening under pressure, it can be opened to traffic immediately after construction. *For more details, please download the PDF or feel free to contact us.
