Adhesion of water-based polyimide varnish to various substrates (stainless steel, film, etc.)
This is a water-based polyimide varnish with improved handling properties (aqueous, low viscosity), enabling high heat resistance and chemical resistance polyimide coatings on various substrates.
Our water-based polyimide varnish utilizes polyamic acid generated by regenerating unnecessary polyimide film during polyimide film processing through a unique chemical treatment, making it an "NMP completely free water-based polyimide varnish." After application to the substrate, this product forms a polyimide resin coating with an imidization rate of over 90% upon drying and curing. Coating on substrates that were previously unprocessable due to the influence of "NMP" solvents can now be considered. This document introduces adhesion properties. 【Representative Product】 NMP-free water-based polyimide varnish 【Features】 ■ Environmentally friendly water-based polyimide varnish ■ High heat resistance and chemical resistance ■ Can be stored at room temperature ■ Suitable viscosity for coating ■ Possible mixing proposals with other resins ■ Improvement of working environment and global environment 【Applications】 ■ Wire coating varnish ■ Improvement of heat resistance in paints, conductive inks, and coatings ■ High-temperature resistant sliding parts and materials for automobiles/aerospace, etc. ■ Adhesives ■ Batteries ■ Heat-resistant paints ■ Prepreg products *For more details, please refer to the PDF document or feel free to contact us.
