Waterborne PU Adhesive for Shoe series boasts a long tack time and excellent bonding strength for various materials, including RB, leather, phylon, synthetic, and PU foam. With a long pot life, it is easy to use and offers excellent heat, water, and yellowing resistance. When high heat resistance is required, a water-emulsifiable polyisocyanate crosslinker (Product No. WPU-70-62I) can be added for optimal performance. Water is a diluent, making it a low environmental pollution adhesive series. Trust this adhesive to deliver the solid, lasting bond your footwear manufacturing process requires. |
