这是我联系的一个客户 他需要的产品跟我们生产的不同 希望对有需要的朋友有个帮助！ 发件人： Rehman Sarwar Rana (ranarehman.lhr@berger.com.pk) Dear Mt.Candy Zhu, its nice to hear from you,we have been in the field of construction chemicals for the last ten years. As far polyurethane is concerned we are interested in single component polyurethane expansion joint salant. the information you have given below shows that you have polyurethane foam instead of polyurethane sealant. if you have polyurethane expansion joint sealant then send its specifications. Apart from this sealant also send the detail of other products,you are manufacturing. Regards Rehman S.Rana
