  • Official site

For water leak repairs! We can fix leaks from various pipes, including water supply, hot water, air, steam, and gas.

If there is a water leak of about 1 MPa, it can be instantly stopped without closing the valve. It is also suitable for use underwater and can be buried. It can be used in a temperature range of -90°C to +260°C, making it compatible with various fluids such as high-temperature steam, air, gas (city gas and propane), and hydrogen sulfide. It can also be used for up to about three days as a temporary measure for acids, alkalis, lubricants, fuels, and other oils and fats. It is compatible with various piping materials, supporting use in a wide range of environments. There is no expiration date, so you can use it anytime without worrying about a shelf life, and you can use it until it is finished. Additionally, it has over 20 years of weather resistance after application, making it suitable for permanent installations. By using the sister product LLFA Smooth (a dedicated filling putty) to level out steps and gaps, it becomes easy to apply to joint steps, screw threads, and uneven areas caused by corrosion. LLFA products have been widely adopted by nine domestic electric power companies, major automobile manufacturers, electrical manufacturers, municipal water departments, and large food and beverage manufacturers. For more details, please contact us.

Applications/Examples of results

It is the most commonly used insulating sealant material in recent years for generator maintenance at hydroelectric power plants in Ontario Power, Ontario, Canada, and for electric and power-related companies in the United States. Since 2007, it has been used by domestic electric power companies in Japan (generator outlet work, 66kV live line work, underground transmission lines, etc.), construction consulting companies (distribution), and equipment maintenance companies (leak repair). It has a proven track record for use in leak prevention for various automotive hoses. Due to its excellent corrosion resistance (over 20 years), it has been adopted in Europe as a protective material for pipelines. ■ For more details, please contact us.

Our company, founded in 1994, has expanded its business from automotive cleaning services to the manufacturing of chemicals used in those services. Starting in the 2007 fiscal year, we ventured into the electrical sector as a new business, beginning with our role as the exclusive distributor in Japan for high-performance self-fusing silicone tape manufactured by GTG Engineering in the United States. We plan to sequentially develop silicone products and urethane products as applications of the technology cultivated in the electrical and electronic sectors and in the manufacturing of automotive chemicals.
