Solvent free polyurethane glue
 
Unlike ordinary moisture curing polyurethanes, it is easy to mix with water, mixing with water for 2~3 minutes, forming a very soft film

 
Product physical properties:
1
Solid content: 100%
2
Appearance: light yellow transparent
3
Main component: Polyurethane
4
Viscosity (MPa
S) at 20 ℃: 3000 ~ 12000
5
gel time (SEC): 30 C     100
  20℃   one hundred and twenty
  10℃   one hundred and sixty
 
Product features:
1
No solvent and formaldehyde
2
It can harden rapidly when mixed with water, and a small amount of water is relatively stable
It can be used for roll coating

3
In practical use, after coating one side, the method of spraying water on the adhesive or the opposite side can be considered, which can greatly shorten the stamping time

4
because the hardened film is very soft, it is the best fit for foam and so on

5
A small amount of coating can be used
Proper foaming can increase the bonding area and improve the bonding force

 
Product purpose:
1
Mutual adhesion of polyurethane and adhesion of polyurethane to nylon non-woven fabric, plywood and wood board
2
Polyurethane sponge adhesive for pillow core (soft type)
3
Bonding of styrene sponges to each other, plywood and wood strips (styrene sponges can be bonded because they do not contain solvent)
 
Next, performance:
Nylon nonwoven / polyurethane sponge

[test items and methods]
Normal test: after the stamping is removed, place it at room temperature for 3 days, and peel it by hand to confirm the adhesion

Boiling water resistance test: after the punch is removed, it shall be placed at room temperature for 3 days and immersed in boiling water
Take it out after 20 minutes and confirm the adhesion immediately
