Waterborne Polyurethane 6028 (PE sheet printing) F0412 Film-forming and permeable Textile coating

Name: Waterborne Polyurethane 6028 (PE sheet printing) F0412 Film-forming and permeable Textile coating
Rating: 4.5 (91 reviews)

Waterborne Polyurethane (WPU) is an environmentally friendly polyurethane resin that uses water as a dispersion medium to replace traditional solvent-based polyurethanes with low VOC, non-toxicity and easy processing. Its core components include: polyol (soft segment): to provide flexibility (such as polyether, polyester polyol). Diisocyanate (hard segment): to give strength (such as HDI, IPDI and other aliphatic, or TDI, MDI and other aromatic). Hydrophilic chain extender: makes polyurethane w
