印度采购需求：荧光增白剂、紫外线吸收剂、抗氧化剂

We are in need of two grades of film-forming polyurethane (PU) resin specifically tailored for solvent-based printing inks designed for use on treated BOPP and PET substrates. The first grade should be compatible with toluene and MEK, while the second grade should be free from these solvents, ensuring we have options that can cater to different printing requirements. Could you please provide recommendations for suitable products that meet these specifications? Additionally, it would be great if you could share the Technical Data Sheets (TDS) and Material Safety Data Sheets (MSDS) for your proposed resins. This information will help us in making a well-informed decision. Looking forward to your prompt response!
