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...

Sometimes, a slight ammonia smell is detected in water-based acrylic emulsions, which confuses many people: is this normal or is there a problem? First, we need to clarify that acrylic emulsions themselves do not produce an ammonia smell. However, during their production, ammonia-containing additives may be added to adjust their performance or improve their stability. These additives gra...

I. Why Must Cigarette Packaging Printing Shift to Water-Based Acrylic Emulsions? Traditional solvent-based inks contain large amounts of volatile organic compounds (VOCs) such as benzene and ketones, which not only harm the health of operators but also easily leave residues on packaging, affecting tobacco safety. Water-based acrylic emulsions, using water as the dispersion medium, have extremely l...

The Adhesive Component of Self-Adhesive Label Materials
- 2026-02-13 10:02:57
- admin
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...
