- Popfil KE levels out structural irregularities within the skin.

- Popfil KE imparts a short a short , even nap to suede .

- Popfil KE increase intensity and depth of dyed shades.

Application :
The action of Popfil KE is dependant on the pH . The optimum pH range for the application of this product is about 3.5-4.5 ie. slightly acidic pH values below 3.5 can cause bonding at the surface only and hardening of the leather . pH values above 5.5 generally result in inadequate bonding with the fibre . It is therefore advisable to apply Popfil KE before neutralizing . WE recommended rinsing the leather beforehand in order to ensure more even uptake of the product .

In chorme retannages , Popfil KE may also be applied together with the chrome tannin , It is important to ensure, however that the pH of the liquor is above 3.5 .
