Product Introduction

Description
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.
Application
Shoe assembly:
Waterborne PU adhesive can be used to bond different parts of shoes together, such as the sole, upper, and lining. It provides excellent adhesion to various materials, such as leather, rubber, and fabric, and can withstand the stresses and strains of daily use.

Insole bonding:
Waterborne PU adhesive can be used to attach the insole to the bottom of the shoe, providing a comfortable and secure fit for the wearer. The adhesive is flexible and durable, ensuring the insole stays in place over time.
