"New Product!" Improved Flexibility: Development of a New Grade of Water-Based Polyimide Varnish (SC-2002) A new grade of water-based polyimide with improved flexibility has been developed! It maintains the same performance as before while enhancing adhesion to various substrates and allowing for coating with a thicker film than before!

Newly developed grade of flexible water-soluble polyimide! It maintains the conventional performance while improving adhesion to various substrates and enabling coating with a film pressure greater than before.

Our company utilizes polyamic acid generated from polyimide film that becomes unnecessary during polyimide film processing, through a unique chemical treatment, to create an "NMP completely free aqueous solution." This product forms a polyimide resin coating with an imidization rate of over 90% after being applied to a substrate and dried and cured. We are pleased to introduce a new grade of water-based polyimide varnish with improved flexibility. Compared to conventional products, it exhibits better adhesion to various substrates and is less prone to cracking. This document presents the coating properties of the new grade product. [Representative Product] Water-based Polyimide Varnish (SC-2002) [Performance Characteristics] High heat resistance and chemical resistance materials *For more details, please refer to the PDF document or feel free to contact us.

Completely NMP-free! A water-based polyimide varnish with excellent handling properties, high heat resistance, and chemical resistance, featuring low viscosity. Documentation is available, and free samples are being provided!

Polyimide varnish has characteristics of high heat resistance and chemical resistance, making it suitable for a wide range of fields and applications, including high-temperature sliding parts and related components for automobiles and aircraft, heat-resistant coatings, special adhesives, and wire insulation. It is a resin that will continue to be used by leveraging these features in the future. However, the current mainstream products are "NMP solution" or "a mixed solution of NMP and water." *NMP = N-methyl-2-pyrrolidone In recent years, "NMP" has raised concerns about its "toxicity," and it has been listed as a restricted substance under the "REACH regulations" in Europe, and it is expected to have an impact in Japan as well. NMP-free water-based polyimide varnish can contribute to "avoiding the use restrictions of NMP" and "reducing VOCs for environmental improvement." This product is expected to further enhance performance and reduce environmental impact in fields requiring high heat resistance and chemical resistance. It has excellent handling properties due to its stability at room temperature and low viscosity, comparable to general functional coatings. It is also believed to enable applications in processing methods that traditional polyimide varnishes could not be applied to. *For more details, please refer to the PDF document or feel free to contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
