---|---|---|---|
Waterborne PU Adhesive for Fabric is suitable for various applications, such as roller-coating lamination of Nylon or Tetoron to PVC film or TPU film, knife-coating lamination for yarn bonding and wind-proof treating. When high heat resistance is required, a water-emulsifiable polyisocyanate crosslinker (Product No. WPU-70-62I) can be added for optimal performance. With low thermal activation temperature, these aqueous PU dispersions are easy to operate and exhibit great water and hydrolysis-resistant properties. Their polymer film shows excellent performance in water and hydrolysis resistance, and their surface exhibits a soft and pleasant touch feeling after applying. The dispersions do not contain heavy metals or compounds and are compliant with the SVHC of REACH requirement, making them environmentally friendly. Waterborne PU Adhesive for Fabric also can be used in footwear industries, such as shoe adhesive formulation. |
