By using BYK additives, the inherent performance of composite materials can be realized.

★World's First Coupling Agent for Carbon Fiber BIC Chemical has developed the world's first coupling agent for carbon fiber that improves the mechanical strength of CFRP using a radical curing resin. BYK-C 8013 / C 8014 has double bonds and reactivity with vinyl ester resin, and it enhances the adhesion between the resin and fibers by forming chemical bonds on the surface of the carbon fibers. As a result, the mechanical strength is significantly improved.

• Composite Materials

The world's first certified additive for wind power generation plants, BYK-C 8001, is a polymer-type coupling agent that improves the mechanical strength of epoxy resin.

BYK-C 8001 was specifically developed for glass fiber reinforced epoxy resin applications. This additive improves mechanical properties by bonding the fibers and the matrix. The degree of improvement depends on the combination of glass fibers and epoxy resin. As the world's first specialty chemical manufacturer, BYK currently offers additives certified by Germanischer Lloyd: BYK-C 8001. Wind turbine manufacturers can use polymer-type coupling agents without further testing in glass fiber reinforced epoxy resin—an important factor for resource efficiency in the globally thriving wind power market.

HP Inc. will hold the "HP Future of Work AI Conference 2025" at Tokyo International Forum, Hall B. At this event, under the message "Freedom to be particular about how we work," we will introduce the possibilities of on-device AI and its practical applications, along with case studies and technological trends. Whether you are considering implementing AI or have already started using it, you are sure to find hints for your next steps. We sincerely look forward to your attendance.

Our company will be exhibiting at the "15th Agriculture WEEK (J-AGRI Tokyo)" held at Makuhari Messe from October 1 (Wednesday) to October 3 (Friday). In the Livestock Materials EXPO zone, we will be showcasing our popular products for livestock and facility horticulture, including the "retrofit mist system for existing fans in barns/greenhouses, easy-to-install integrated mist system TM" and the "new product, large cylindrical mist system TM," along with related products. We sincerely look forward to your visit. Our booth number is 36-34 in Hall 9 of Makuhari Messe.

Yakeshi Electric will exhibit at the Space Science and Technology Union Conference to be held in November 2025. ■69th Space Science and Technology Union Conference https://smartconf.jp/content/sstc69/ Dates: November 25 (Tuesday) - November 28 (Friday), 2025 (4 days) The Space Science and Technology Union Conference is a large-scale event where people involved in space, including JAXA, various research institutions, universities, and private companies, gather together. Our company develops electronic sources for small satellites (including impregnated cathodes and LaB6) and manufactures peripheral components such as sensors and power supply units. This time, we plan to expand our display of electronic sources and include additional components such as tantalum and Inconel! In particular, electronic sources like impregnated cathodes are often purchased from overseas due to the limited number of domestic manufacturers, which can lead to difficulties in fine adjustments and flexibility. However, our company offers: ● Control of porosity and selection of emitters ● Manufacturing according to desired sizes and shapes ● Production starting from one unit ● Stable domestic procurement We can provide solutions tailored to your research and development needs! Please feel free to consult with us.

We will introduce an overview of "IATF16949:2016," which is an essential requirement for entering the automotive industry, along with key points considering the current situation of industry trends. In planning for certification of sector standards, we have structured the training content for companies that are gathering information on what to do first and planning to obtain certification. * We have received inquiries from business partners and are struggling to respond. * We are planning to obtain certification but do not fully understand the specific preparations and initiatives required. This seminar is recommended for companies seeking to acquire knowledge and gather information about sector standards.
