"Film recycling" and "VOC-free" water-based polyimide varnish!
Contributing to the achievement of SDGs through film recycling! This is an environmentally friendly polyimide varnish made from recycled polyimide film that becomes unnecessary during manufacturing, eliminating NMP.
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 coatings. Its use is expected to continue in the future, leveraging these features. Our water-based polyimide varnish utilizes polyamic acid generated by uniquely chemically processing polyimide film that becomes unnecessary during polyimide film processing. It is a water-based polyimide varnish that does not use NMP, which is commonly used as a solvent. This initiative contributes to achieving the SDGs through "using unnecessary polyimide film as raw material (REUSE)" and "reducing VOCs through water-based formulation." This product is expected to further improve performance and reduce environmental impact in fields that require high heat resistance and chemical resistance. Additionally, 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 application to processing methods that conventional polyimide varnishes could not be applied to. *For more details, please refer to the PDF document or feel free to contact us.*
basic information
【Features】 Conventional polyamic acid-based polyimide varnishes have very high viscosity, resulting in poor handling properties and low storage stability, which necessitated refrigeration. In contrast, this developed product addresses these disadvantages, providing excellent handling properties with storage stability at room temperature and low viscosity comparable to general functional coatings. ■ Environmentally friendly water-based polyimide varnish ■ High heat resistance and chemical resistance ■ Can be stored at room temperature ■ Viscosity suitable for coating ■ Mixing proposals with other resins are possible ■ Improvement of work environment and global environmental enhancement *For more details, please refer to the PDF document or feel free to contact us.
