In May 2024, Kao launched a new release agent called "Luna Flow." Behind this development lies a unique interface science inspired by the mechanisms of plants and a challenge towards sustainability. The original "slippery" technology, inspired by the sea cucumber, is now attracting attention from various business sectors. In this article, we spoke with two representatives from Kao's Chemical Division and a representative from Mitsui & Co. Plastics, the sales partner, to delve into the behind-the-scenes of the "Luna Flow" development. ------ Is it only for reducing the load on molds and for release agent applications? There has been significant interest in using it as a release agent for rubber and plastic molding, but there are also inquiries from the construction industry wanting to "prevent soil adhesion." There is a lot of interest from unexpected applications, and some very intriguing results have emerged. Please check the article for potential expansions into other applications. ↓ You can read the article about the development of the fluorine-free coating agent "Kao Luna Flow" through this 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.

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.
