Water base shoe adhesive  1025

Huacheng High-tech is specialized in water base shoe adhesive which is one of the largest specialized producers of 

water base shoe adhesive.

1.characteristics:

The water base shoe adhesive 1025 is water base polyurethane dispersion which is a kind of anionic and thermal 

activation adhesive. The obvious advantage of the product is: environmental protection non-toxic harmless

 to operation workers body; non-flammable and explosive safe use; easy to clean; the cost is lower than the oily 

rubber shoes; no yellowing, water resistance, good heat resistance.

4,Applying process:

    1. Surface treatment: firstly, distinguish material quality. To do some suitable Treatment for the surface of adhesive 

materials before using such as oil removing and derusting, moisture removing and polishing etc. Oil removing can make 

the surface of adhesive materials looks like no oil, impurity and other pollution material. Decontamination can use 120# 

gasoline tianna water, methylbenzene or acetic ether etc.General polishing lightly polished with No. 0 or No. 1 sandpaper.Use different agents for different materials, the optional standard is "like dissolves like", and its purpose is to increase the 

adhesion of PU material.

    2. To coat according to different materials: usually, one time is okay, but it is suggested to coat two times for mushy 

material.

    3. Operation process:to distinguish adhesive materials exactly--surface decontamination--to add suitable treating-agent--drying (70°CX3-5)--coating--drying (70°CX4-5’)--gluing--Pressing--cooling--arrangement--packing.

    4. Gluing method:gluing in the period of adhesion-keeping that is to glue in 0-3' Before the material comes from drying oven. It should be in 2' in winter. Try to glue correctly one time.

    5. Pressing method: adjust the press, the time of pressing is 8-12s'.Make it under the condition of no changing of basic materials, the higher the pressing power, the better.

6. Bad coating can make the following effects: the glue line is too thick, cost increase; some position can't be dry

 completely and meantime causes "plot glue" which affect the bonding quality;Layer uneven causes part of the region 

"plot glue";Portion bounce, blistering phenomenon and etc.

5,Precaution:

    1. Before treatment, it is necessary to distinguish the materials, choose different additive according to materials.

    2. Treatment should be uniformity fully. Change the accessory frequently such as gauze, cotton and etc.

3. To coat after the additive is dry completely. The coating quantity should be uniformity.

4. No adding hardener can get the requirements,easy to operate,reduce cost and prevent waste.

5. After coating, the temperature of drying should be suggested at 60-70°C, the time of drying suggested at 4-5min. Place it in moisture place,otherwise likely to cause the surface crust or surface of the white mist, then bad.

6. To choose the best time of adhesion for gluing.

7. It must be finishing the whole pressing within the time of adhesion-keeping.

    8. Setting the time and scale of pressing suitably. The bigger the pressing, the better of catching. Time should be 

controlled in 8-12'.

    9. To clean the brush in water.

   10. To remove the pollution by dressing agent so that the solvent can't infiltrate into the layer of binding agent.
