A. Summarization
PU-501 polyurethane dry laminating adhesive main chemical
G-75 polyurethane dry laminating adhesive solidifying chemical
PU-501/G75 is a kind of double-component polyurethane dry laminating adhesive with high quality. It can be applied to the lamination of different materials such as OPP, CPP, PE, CPE, PET, NY, Al and also VMPET, VMCPP.
B. Characteristics
1. Good viscosity to the film material;
2. With high viscosity speed, being applied to the laminating of kinds of rigid material like aluminum foil or material requiring high vacuum film laminating;
3. Good performance of anti-freeze, medium resistance, acid & piquancy resistance and acid & alkali resistance;
4. Good humidification and leveling property, widely adapted to the coating with high speed

Note: Our producing process is under strict supervision and our product is under strict quality control. The above info is for reference only. The proportion needs to suit the special producing, especially the proportion of the main chemical and the solidifying chemical, which is based on the structure of the laminating material, the environmental moisture, the water content in the solvent, printing ink, the softness of the printing needed by users. Users are required to test before usage. We are not responsible of the loss due to the wrong operation.
