One component of self-adhesive label materials is the adhesive, also known as glue. The adhesive determines the label's stickiness and applicable scenarios. The adhesive is also the bonding layer between the label and the object it's applied to; its stickiness, temperature resistance, and magnetic adhesion directly affect the label's adhesion effect. It can be divided into the following categories...

01 Polyurethane The structure of polyurethane is formed by the reaction of polyisocyanates (e.g., diisocyanate OCN-R-NCO) and polyols (e.g., diol HO-R-OH), where urethane segments are repeating structural units. Polyurethane structures have structures similar to amide and ester groups; therefore, the chemical and physical properties of polyurethane are between those of polyamides and polyesters. S...
