SPIXAREA HR Series

The SPIXAREA HR series is a high-heat-resistant solvent-soluble polyimide varnish.

[1] Since it is already an imidized polyimide solution, thermal treatment like that of polyamic acid types is unnecessary. [2] It is a new type of solvent-soluble polyimide that can achieve low Tg while being solvent-soluble. [3] By simply applying and drying it, a highly heat-resistant polyimide coating can be easily formed. [4] Unlike polyamic acid types, it has less time-dependent change due to environmental factors, resulting in excellent storage stability.

Newly developed product: Coating performance of high durability grade SC-2402.

Introducing the coating properties of water-based polyimide varnish with improved durability. Physical property data on heat resistance, mechanical strength, and electrical characteristics is included!

■NMP Free This is a highly safe material that does not contain NMP (N-Methyl-2-pyrrolidone), a solvent commonly used in polyimide varnishes. NMP has a high reproductive toxicity classification of 1B under GHS and is classified as an SVHC (Substance of Very High Concern) under the EU chemical regulation REACH. ■Excellent Durability - Heat Resistance, Mechanical Strength, Electrical Properties, Chemical Resistance This material has high durability comparable to that of conventional solvent-based polyimide varnishes. ■Reduction of VOC and CO2 Emissions - Prevention of Air Pollution, Mitigation of Global Warming Since it does not contain the organic solvent NMP, it is expected to reduce VOC (volatile organic compounds) and indirectly lower CO2 (carbon dioxide) emissions. ■Utilization of Recycled Resources - Consideration for SDGs, Circular Economy, Green Chemistry, etc. There is a sustainable lineup that utilizes scraps from polyimide films. ■Can be Stored at Room Temperature Conventional solvent-based polyimide varnishes require low-temperature storage in refrigeration or freezing to maintain quality, but this product has high stability and can be stored at room temperature. Special management in refrigeration or freezing facilities is not necessary. *Please refer to the PDF document or feel free to contact us.
