I'm looking for PU Glue with specific characteristics and applications in mind. Could you provide details on the available formulations, including any variations in viscosity, strength, and curing time? Additionally, if you could share info about your packaging options, that would be great. Also, I'm interested in your pricing structure including bulk purchase discounts and lead times for delivery. It would be helpful to know about the minimum order quantities as well. If you have any technical data sheets or sample products, please let me know!
