New materials in the infrastructure sector expected to enhance longevity: silicone sealing materials.
What is the new material that holds the key to the longevity of infrastructure, civil engineering silicone sealing material? [Presentation materials available]
As sustainable infrastructure maintenance systems gain attention, it is said that structures like highways and bridges last for 40 years, but the durability of sealing materials, which are standard in the civil engineering industry, is only about 5 to 10 years. In other words, there are concerns about the insufficient lifespan of the sealing materials used to fill gaps, rather than the structures themselves. ＼Do you have any of these concerns?／ 【1】I want to achieve long lifespan, but I can't afford the time or cost. 【2】Are there sealing materials that can be easily repaired? 【3】I want to consider "new materials" for civil infrastructure longevity plans. You can rely on Dow and Toray's silicone sealing materials for these concerns! They are characterized by high durability and weather resistance, with a lifespan equivalent to 50 to 60 years. They are recognized in the construction industry as maintenance-free sealing materials, and there are numerous achievements within Japan. Additionally, a comparison of the aging of modified silicone materials and silicone materials was conducted through a 10,000-hour xenon weather resistance test. It was confirmed that the silicone material showed no signs of cracking and maintained its initial flexibility. This flexibility and adaptability are also one of its major features.
