Silicone sealing materials for the longevity of civil engineering and infrastructure such as highways.
Silicone sealants are becoming the chosen material for repairs in civil engineering and infrastructure, such as highways.
The "Highway Tech Fair 2025" was held at Tokyo Big Sight. Mitsui & Co. Plastics Ltd. and Dow-Toray Co., Ltd. showcased silicone sealing materials for the repair of civil engineering and infrastructure such as highways. Many attendees were present to address on-site challenges such as "repair, longevity, labor-saving, and decarbonization." ＼Do you have any of these concerns?／ 【1】Considering measures for deterioration and water leakage of expansion joints on highways 【2】Wanting to extend the repair cycle and reduce maintenance burdens 【3】Looking for repair materials that can achieve longevity You can rely on Dow-Toray's silicone sealing materials for these concerns! For the repair of expansion joints on highways, you can repair the deteriorated parts with silicone sealing materials while leaving the expansion joint itself intact. One of the attractions is that it allows for longer-lasting repairs compared to replacing the entire structure. Additionally, conventional organic materials show noticeable cracking and deterioration in about five years. In contrast, silicone sealing materials significantly extend the repair cycle, which is a major feature. You can download materials from our website via the link below or feel free to contact us.
