To satisfy our customers' needs, we offer a range of varnish grades optimized for different applications and characteristics!

"Meireji Coat" is a polyimide precursor made from BPDA (3,3',4,4'-biphenyltetracarboxylic dianhydride). The coatings produced from the polyimide precursor exhibit excellent performance. Polyimide coatings show high thermal decomposition temperatures and do not soften, flow, or decompose at the usage temperature, making them suitable for high-temperature processes. 【Features】 ■ A range of varnish grades optimized for different applications and characteristics to meet customer needs. ■ Viscosity and concentration can be customized to match customer usage conditions. *For more details, please download the PDF or feel free to contact us.

• Coating Agent

It is possible to obtain a polyimide coating with excellent heat resistance, chemical resistance, and electrical insulation properties!

"Meireji Coat" is a polyamic acid solution, which is a precursor to polyimide (high-performance engineering plastic). By performing solvent removal and imidization reactions, it is possible to obtain a polyimide coating with excellent heat resistance, chemical resistance, and electrical insulation properties. It can be diluted with NMP or DMAc (N,N-Dimethylacetamide), or adjusted in temperature to be used at the desired solution viscosity. 【Features】 ■ We offer varnish grades optimized for each application and characteristic to meet customer requirements. ■ Viscosity and concentration can be customized to match customer usage conditions. *For more details, please download the PDF or feel free to contact us.

• Coating Agent

Can be produced at the same heat treatment temperature as conventional polyimide! The porosity can be adjusted as desired.

"Porous Polyimide" is a porous-forming varnish primarily based on PMDA-ODA. It can be produced at the same heat treatment temperature as conventional polyimides. The resulting film exhibits a low dielectric constant, and the porosity can be adjusted as desired. Please feel free to contact us when you need our services. 【Features】 ■ Low Dielectric Constant: The resulting film shows a low dielectric constant (can be adjusted arbitrarily from 2.0 to 2.9). ■ Control of Porosity: The porosity can be adjusted as desired (porosity from 1% to 70%). *For more details, please download the PDF or feel free to contact us.

Varnish customized for optical applications! Achieves high transmittance over a wide wavelength range.

We would like to introduce our "Transparent Polyimide." This product can be molded with heat treatment below 250°C. Additionally, the resulting film demonstrates high insulation properties. Please feel free to contact us when you need assistance. 【Features】 ■ Insulation: The resulting film shows high insulation properties. ■ Transparency: Achieves high transmittance over a wide wavelength range. ■ Low-temperature molding: Can be molded with heat treatment below 250°C. *For more details, please download the PDF or feel free to contact us.

• Other polymer materials

Soluble in general solvents (such as DMAc and NMP)! Can be used without imidization treatment.

"Soluble polyimide" is a polyimide solution or polyimide powder that can be molded at low temperatures compared to conventional polyimide precursor varnishes. Molding is possible at 100 to 200°C depending on the choice of solvent. It completely dissolves (DMAc immersion test). Please feel free to contact us when you need our services. 【Features】 ■ Soluble: Soluble in common solvents (DMAc, NMP, etc.) ■ Low-temperature molding: Molding is possible at 100 to 200°C depending on the choice of solvent ■ No imidization required: Can be used without conventional imidization treatment (300 to 400°C) *For more details, please download the PDF or feel free to contact us.

[Instructor] Hiroto Hayashi, Attorney at Law, New York State, Mori Hamada & Matsumoto Law Firm, Foreign Law Joint Enterprise [Key Lecture Content] Recently, batteries are expected to serve as a balancing power source for the realization of renewable energy as a primary power source. Due to changes in the business environment brought about by market development and government support measures, opportunities in the battery business are expanding. For grid-connected batteries, there are multiple options for long-term decarbonization power source auctions, tolling models, and merchant models, and the points of project development vary depending on the offtake method. Additionally, with the spread of the FIP system, the installation of batteries alongside renewable energy generation facilities is also progressing. In this lecture, we will explain the systems related to batteries, as well as key points for contract creation and negotiation, and financing necessary to steadily advance projects. We will also outline the challenges and prospects for project development and project finance formation according to each offtake scheme.

[Lecturer] Hideo Yamada, Ph.D. Honorary Professor, Waseda University Visiting Professor, Business Breakthrough University Graduate School [Key Lecture Content] Companies face various trade-offs (dilemmas) such as quality vs. cost, inventory levels vs. service levels, and standardization vs. differentiation. Traditionally, companies have responded to trade-offs by (1) finding a balance or (2) prioritizing one over the other. However, this does not lead to fundamental solutions. In this lecture, I will propose a third method that is neither balancing nor prioritizing. Using case studies from over 50 Japanese companies, I will explain it in an easy-to-understand manner. If we can turn long-standing trade-offs into trade-ons (coexistence), business opportunities will arise. [Lecture Topics] 1. What is a trade-off? 2. Trade-offs between customers and companies 3. Trade-offs within companies 4. Trade-offs within customers 5. How to turn trade-offs into trade-ons 6. Steps for exploration 7. Q&A / Business card exchange

[Lecturers] Corporate Partner, Nishimura & Asahi Law Office Osaka, Mr. Satoshi Niki Associate, Nishimura & Asahi Law Office - Foreign Law Joint Enterprise, Mr. Shu Numazawa [Key Lecture Content] In recent years, the diversification of defense cooperation and advancements in dual-use technology have significantly changed the management and international sharing of advanced technologies. This lecture will clarify the basic structure of Article 3 of the Japan-U.S. Technology Agreement and the significance of "similar treatment," while explaining the institutional transformation brought about by the introduction of the non-public patent application system under the Economic Security Promotion Act. Furthermore, considering the relationship between this system and the Japan-U.S. Technology Agreement, we will examine how to reposition the patent applications and secrecy management of defense-related technologies within the context of expanding international joint research and multilateral defense cooperation. [Lecture Items] 1. Diversification of defense cooperation and advancements in dual-use technology 2. Basic structure of Article 3 of the Japan-U.S. Technology Agreement 3. Practical application of "similar treatment" 4. Introduction of the non-public patent system (Economic Security Promotion Act) 5. Relationship between the non-public patent system and Article 3 of the Japan-U.S. Technology Agreement 6. Expansion of international joint research and reevaluation of Article 3 7.
