EB4260A/EB4260B is a high-strength, anti-aging functional two-component aromatic polyurethane adhesive. Suitable for laminating of metal/polymer printed film for can packaging, and the finished product has the characteristics of high strength, resistance to forging, corrosion resistance, etc. It can withstand 0~180° cold bending without delamination.
These properties are typical but do not constitute specifications.
