Choosing silicone sealants to reduce life cycle costs (part one)

Choosing silicone sealants to reduce life cycle costs (part one)

Contributes to reducing life cycle costs! High-durability silicone sealing material 【*Article currently published! View from the link】

Currently, the country is engaged in efforts to extend the lifespan of infrastructure and establish a sustainable infrastructure maintenance system. It is said that structures like highways and bridges last for about 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, the concern is more 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】Repeated repairs or updates due to the deterioration of sealing materials 【2】Want to use materials that can maintain flexibility and adaptability for a long time 【3】Looking for sealing materials for working joints and expansion devices 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 in Japan. ↓You can view the article on silicone sealing materials that reduce lifecycle costs from this link.

Choosing silicone sealants to reduce life cycle costs (after)

Choosing silicone sealants to reduce life cycle costs (after)

Achieve both infrastructure longevity and reduced maintenance costs simultaneously! Silicone sealing materials [*Article currently published! View from the link*]

Silicone sealants are high-performance but also expensive. Many civil engineering professionals have this impression, which has significantly impacted the initial construction costs of projects and has been a factor hindering their widespread adoption. ＼Do you have any of these concerns?／ 【1】Repeated repairs or updates due to the deterioration of sealants 【2】Want to use materials that can maintain flexibility and adaptability over a long period 【3】Want to advance material selection considering life cycle costs Leave these concerns to Dow and Toray's silicone sealants! With the aging of infrastructure, prioritizing longevity is essential, and it is necessary to consider the total cost over 40 years from the budgeting stage. While the initial cost of silicone materials may be high, it reduces the need for renovation work that used to occur every 5 to 10 years, meaning the total life cycle cost over 40 years can be lowered. In fact, cases where silicone is adopted for such reasons are increasing. ↓You can find articles on silicone sealants that achieve life cycle cost reduction at this link.

The savior of civil infrastructure renovation, Dow and Toray's silicone sealing material.

The savior of civil infrastructure renovation, Dow and Toray's silicone sealing material.

What is civil engineering silicone sealing material, the key to the longevity of infrastructure?

As the country is making efforts to extend the lifespan of infrastructure, the selection of new materials is also becoming more active. In this context, silicone sealing materials, which are said to have a lifespan more than five times that of conventional organic sealing materials commonly used in the civil engineering industry, are gaining attention. ＼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 the civil infrastructure longevity plan. Leave these concerns to Dow and Toray's silicone sealing materials! Currently, the civil engineering sealing materials used in agricultural waterways, dams, bridges, etc., are mostly polyurethane-based or modified silicone-based organic materials. This means that compared to the structures that are said to last 40 years, the durability of sealing materials is only about 5 to 10 years. Dow and Toray's silicone sealing materials solve this problem, with a durability of 50 to 60 years, and they also excel in durability, weather resistance, flexibility, and temperature adaptability!

Silicone sealing materials for the longevity of civil engineering and infrastructure such as highways.

Silicone sealing materials for the longevity of civil engineering and infrastructure such as highways.

Silicone sealants are becoming the preferred 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 the 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! In the repair of expansion joints on highways, it is possible to repair the deteriorated parts with silicone sealing materials while leaving the expansion joints themselves intact. One of the attractions is that it allows for longer-lasting repairs compared to completely replacing the structure. Additionally, conventional organic materials tend to show cracks and deterioration within about five years. In contrast, silicone sealing materials are characterized by their ability to significantly extend the repair cycle.

Silicone sealants that also address environmental issues.

Silicone sealants that also address environmental issues.

Repair solutions that support the long lifespan and maintenance of highways and bridges, silicone sealing materials.

While the recognition of silicone sealing materials is spreading, environmental responses such as "decarbonization" have become major themes. ＼Do you have any of these concerns?／ 【1】Considering measures for the deterioration and water leakage of expansion devices on highways 【2】Wanting to extend the repair cycle and reduce maintenance burdens 【3】Looking for repair materials that also consider environmental impact Leave these concerns to Dow and Toray's silicone sealing materials! Producing 1 kg of silicone generates 7 to 10 kg of CO₂, but Dow and Toray's silicone sealing materials have improved the manufacturing process to halve emissions, with the remainder being offset through their own forest conservation activities. Not only do they contribute to "long lifespan and reduced waste," but they also help in carbon reduction and decarbonization during the manufacturing stage. We offer repair solutions that support solving challenges in infrastructure maintenance! You can download materials from our website via the link below or feel free to contact us.

Silicone sealant that maintains initial flexibility and adaptability even after 10 years.

Silicone sealant that maintains initial flexibility and adaptability even after 10 years.

Countermeasures for the insufficient lifespan of sealing materials: the option of high-weather-resistant silicone! 【*Article now available! View via the link】

Currently, the country is engaged in efforts to extend the lifespan of infrastructure and create a sustainable infrastructure maintenance system. It is said that structures like highways and bridges last for about 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, the concern is more 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】Repeated repairs or updates due to the deterioration of sealing materials 【2】Want to use materials that can maintain flexibility and adaptability for a long time 【3】Looking for sealing materials for working joints and expansion devices You can rely on Dow and Toray's silicone sealing materials for these concerns! In fact, a comparison of the aging deterioration of modified silicone and silicone materials was conducted through a 10,000-hour xenon weathering test. The modified silicone showed hardening and cracking due to aging, leading to leaks and damage, while the silicone material showed no signs of cracking and maintained its initial flexibility. This flexibility and adaptability are significant features of the sealing materials. ↓You can read the article on silicone sealing materials from this link.
