Description EG7075A/EG7075B is a 2-component aromatic polyurethane adhesive with high solid content and high transparency. It offers laminated films high initial bonding strength, high transparency, and high peeling strength, especially its excellent softness and wrinkle resistance. The laminated films has very good wetting properties and excellent coating processability, which is widely used in laminating of various treated film like BOPP﹑PET﹑NY﹑PA﹑PE﹑CPP﹑VMPET﹑VMOPP﹑VMCPP﹑AL﹑etc .
