Water-based polyimide varnish - List of Manufacturers, Suppliers, Companies and Products

High heat resistance and chemical resistance material Water-based polyimide varnish (SC-1901)

Water-based polyimide varnish with excellent handling and environmental safety, suitable for a wide range of applications such as components requiring high-temperature resistance, heat-resistant coatings, special adhesives, and wire insulation.

Currently, many polyimide solutions sold in the market are primarily "NMP solvent" or "a mixture of NMP and water." *NMP = N-Methyl-2-pyrrolidone "NMP" has high solubility and is used in a wide range of applications, including solvents, stripping agents, cleaning agents, and inks. In recent years, concerns about its "toxicity" have arisen, and it has been listed as a "substance subject to restrictions under the REACH regulation" in Europe, and it is expected to have similar impacts in Japan in the future. NMP-free water-based polyimide varnish can contribute to "avoiding the use of NMP" and "reducing VOCs for environmental improvement." Our company offers an "NMP completely free aqueous solution" that utilizes polyamic acid generated by the unique chemical treatment of polyimide film that becomes unnecessary during polyimide film processing. This product forms a polyimide resin coating with an imidization rate of over 90% after being applied to the substrate and dried and cured. 【Representative Product】 Water-based Polyimide Varnish (SC-1901) 【Performance Characteristics】 High heat resistance and chemical resistance materials *For more details, please refer to the PDF document or feel free to contact us.

NMP-free water-based polyimide varnish (developed in-house by MP Gokyo F&C)!

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.
