Waterborne bonding of fabric PU glue
This type of PU glue is waterborne PU glue and is suitable to be used as shoe adhesive. This type of glue is solvent free so it is very friendly to environment.
This type of PU glue includes WPU-70-17GLW and WPU-70-17GHW. The main difference of these two grades is their viscosity. WPU-70-17GHW has higher viscosity and WPU-70-17GLW has lower viscosity. You can add thickener in WPU-70-17GLW to increase its viscosity.
Characteristics of waterborne PU glue
- Good bonding to RB, leather, phylon, synthetic, PU foam, etc.
- Excellent water, heat and yellowing resistance
- Long pot life
- Easy to use
- Eco-friendly

Operation method
1. Adding 3-5% WPU-70-62I by weight to the water based PU adhesives and mix by agitator at 300-500 RPM for 8-10 mins. Please use up the mixed cement within its pot life (2 hours).
2. Add 1% more WPU-70-62I during raining days and high humid days.
3. When mixed with PU dispersions, it will generate CO 2 , so don’t seal mixed cement.
