Advantages of water based PU adhesive
1.Free of VOC, safe to environment and worker's health
2.Cost saving, consumption is less than solvent based PU adhesive.
3.Water solvent, safe for transportation and storage, which lower shipping cost
4.Almost no odor, the air in workshop can be improved.
Application of water based PU adhesive
The water based PU adhesive is mainly used for bonding PVC, PU, fabric, leather, EVA, rubber, and TPR etc in footwear industry.
Appearance: milky white liquid
Solid Content : 45-50%
Viscosity : 3500-4500CPS/25℃
Heat Resistance: 55-60℃
Drying Time: 10-15min
Brushed with small brush or machine. Heat activation is required after brushing glue.
Hardener can be used if there is higher requirement on heat resistance and water resistance.
Identify the material→clean the material surface→brush primer→dry in oven（70℃±5℃X3-5’） →cementing→dry in oven（70℃±5℃X4-5’） → attaching → press → cooling → clear up→ packing
Improper cementing will lead to following outcome.
If the cement layer is too thick, it will not dry completely, which will affect the bonding effect.
For uneven cementing, part of the material surface will accumulate cement, lack of cement or blister.
Packed in plastic drum.
Shelf Life and Storage
Under 5-30℃, the adhesive can be stored within 3~6 months. The storage temperature should NOT be under 0℃.
