印度采购需求：功能性成品膜,功能性窗膜

I am interested in sourcing high-quality photochromic films specifically designed for architectural and building applications. These films should effectively respond to varying light conditions, providing both functionality and aesthetic appeal for modern structures. It's crucial that the films have excellent durability and UV resistance, catering to both commercial and residential projects. Could you please provide detailed specifications, including performance characteristics, potential applications, and any available certifications? Additionally, I'm keen to know about your production capacity, lead times, and bulk pricing options. Understanding your customization capabilities would also be beneficial, as we may require specific features to meet unique project demands. Looking forward to your prompt response!
