Water-based polyimide varnish with high handling properties (aqueous, low viscosity, and storage stability).
High heat resistance, chemical resistance, can be stored at room temperature, and low viscosity handling properties expand the application of environmentally friendly water-based polyimide varnish (NMP-free).
This is a completely NMP-free water-based polyimide varnish. 【Features】 ■ Environmentally friendly water-based polyimide varnish This is an environmentally friendly water-based polyimide varnish that uses NMP made from recycled polyimide film scraps. It does not fall under hazardous materials according to fire safety laws. ■ High heat resistance and chemical resistance It has higher heat resistance and chemical resistance compared to general resins. ■ Can be stored at room temperature Conventional polyimide varnishes have a short quality assurance period and require refrigeration, but this product can be stored long-term at room temperature, making management during storage easier. ■ Suitable viscosity for coating Compared to general polyimide varnishes, this product has a lower viscosity, making it suitable for application methods that could not be used with high-viscosity materials. ■ Proposal for mixing with other resins Mixing with other resin emulsions, such as fluorine-based emulsions, is expected to yield synergistic effects. ■ Improvement of work environment and global environment NMP-free water-based polyimide varnish contributes to "avoidance of NMP usage regulations" and "reduction of VOCs for global environmental improvement." *For more details, please refer to the PDF document or feel free to contact us.
basic information
This product forms a polyimide resin coating with an imidization rate of over 90% by applying it to a substrate and then drying and curing it. This product is expected to further improve performance and reduce environmental impact in fields that require high heat resistance and chemical resistance. Additionally, with improved handling properties, it is believed that it can be applied to processing methods that conventional polyimide varnishes could not be used for. *For more details, please refer to the PDF materials or feel free to contact us.*
