HY-752 polyurethane dry laminating adhesive main chemical
HY-G65 polyurethane dry laminating adhesive solidifying chemical
HY-752/G65 is a kind of double-component solvent polyurethane dry laminating adhesive with low viscidity and high solid content. It can be applied to the lamination of different materials such as OPP, CPP, PE, CPE, PET and etc.
B. Characteristics
1. Good viscosity to kinds of film material, adapt to kinds of plastic film, metalized plastic film;
2. Good performance of anti-freeze, weather resistance and hydrolyzation resistance;
3. Good initial viscidity;
4. With high solid content and low viscidity, good moisture and leveling property, adapt to the laminating of high-speed coating and soft packing material with high transparence.
